242 SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY FIGURE 81.—Eunice norvegica (neotype, KNVSM No. 63): a, anterior end, lateral view; b, compound falciger, parapodium 54; c, subacicular hook, parapodium 54; d, pectinate seta, parapodium 54; e, parapodium 54, anterior view. Eunice ornata (syntype, USNM 4874): f, pectinate seta, parapodium 15; g, compound falciger, parapodium 15; h, parapodium 15, anterior view; i, anterior end, lateral view; j, parapodium 40, anterior view; k, aciculae, parapodium 40; 1, compound falciger, parapodium 40; m, acicula, parapodium 40; n, pectinate seta, parapodium 45; o, subacicularhook, parapodium 45. (Scale bars in mm.)
NUMBER 523 243 digitiform. Anterior notopodial cirri long, tapering, with 3 cylindrical articulations. Notopodial cirri retaining same size and shape throughout, being especially prominent in posterior setigers; articulations lost by beginning of branchial region. Limbate setae slender, marginally serrated. Pectinate setae (Figure 8Id) tapering, flat Both marginal teeth slightly longer than other teeth; -15 teeth present. Shafts of compound falcigers (Figure 81b) tapering, marginally smooth. Appendages short, tapering to very large heads, bidentate. Proximal teeth larger than distal teeth, tapering, directed laterally. Distal teeth curved. Guards distally irregularly, symmetrically blunt; mucros absent. Pseudocompound falcigers and compound spinigers absent. Aciculae amber or chestnut colored, tapering, straight; cross-section round. Subacicular hooks (Figure 81c) from dark amber or chestnut colored, bidentate. Hooks first present from setigcr 42 (44 in other specimen), present in all setigers thereafter, sometimes paired. Hooks strongly tapering to small heads. Proximal teeth very much larger than distal teeth. Both teeth directed distally. UNKNOWN MORPHOLOGICAL FEATURES.—Pygidium and anal cirri. EXPECTED STATES OF UNKNOWN MORPHOLOGICAL FEA- TURES.—None. CHARACTERS USED IN PREPARATION OF KEY NOT SCORED.—Inappropriate Characters: 56, 58, 59. Unknown Characters: 4,6,42,74, 78. ASSUMED STATES FOR PURPOSE OF PREPARING KEY.— None. REMARKS.—No type material is available for this species. Linnaeus accepted the species as new in a letter to Bishop Gunnerus in Trondheim dated 1 December 1766 (Gunnerus, 1768:51, footnote) and published a brief description next year (Linnaeus, 1767). It is not clear from Gunnerus' remarks or from the original description if Linnaeus saw any specimens or just reacted to Gunnerus' description and appended illustrations, which are excellent Incidentally, the species is called Nereis norvegica on Gunnerus (1768, pi. 2: fig. 7) even if he used a different name in his text. Gunnerus (1768) is a description of deep-water corals of Norway and their faunal associates; he mentioned several localities including Statsbygd (Gunnerus, 1768:38). He specifically stated that he had seen fresh material of corals from Statsbygd and that he had found his Nereis madreporae pertusae on fresh coral material (pp. 44-45). The reef at ROberg, which is in Statsbygd, is here considered the type locality for the species and one of two specimens listed above has been designated as neotype to define and delimit a species that has been reported from a variety of localities worldwide. For most of last century two species, both present on ahermatypic reefs, were confounded under the name E. norvegica. This synonymy led to the description of Leodice gunneri by Storm; this problem is discussed in some detail above. Eunice norvegica belongs to group B-2 as the groups were defined by Hartman (1944) and Fauchald (1970), but aciculae and subacicular hooks are relatively light-colored compared to the dark-brown to black aciculae and hooks present in most species in the group. It is listed with similar species in Tables 27 and 30. It is the only species in Table 30 to combine short branchiae with inflated bases of ventral cirri limited to median setigers. 138. Eunice notata (Treadwell, 1921) TABLES 33,37-39 Uodice notata Treadwell, 1921:52-54, figs. 164-173, pi. 4: fig.12. Eunice afra.—Hartman 1956:282 [in part, not Peters, 1854]. COMMENTS ON MATERIAL EXAMINED.—The type material has been lost. The description by Treadwell, although somewhat incomplete, is sufficient to characterize the species. DESCRIPTION.—Complete specimen with 95 setigers; total length 40 mm; width about 1 mm. No antennae outreaching peristomium, without articulations. Peristomial cirri short, without articulations. Maxillary formula 1+1, 4+4, 5+0, 3+6, and 1+1; Mx III illustrated as short; part of distal arc with left Mx IV. Branchiae present, not reduced in mid-body region. Branchiae from setiger 14 to setiger 70. Branchiae terminating well before posterior end, present on more than 65% of total number of setigers. Small specimens with single, strap-like filaments only; larger specimens with up to 3 filaments. Ventral cirri basally inflated from about setiger 10; distribution of inflated bases otherwise unknown. Notopodial cirri short, tapering, supported by internal aciculae in all setigers. Notopodial cirri without articulations. Limbate setae marginally smooth. Pectinate setae tapering, furled. Both marginal teeth longer than other teeth; -20 teeth present. Shafts of compound falcigers inflated, marginally serrated. Appendages with nearly parallel sides, bidentate. Proximal teeth larger than distal teeth, triangular, directed slightly basally. Distal teeth distinctly curved. Guards symmetrically bluntly pointed, marginally serrated; mucros absent. Pseudocompound falcigers and compound spinigers absent Aciculae tapering, distally slightly bent. Aciculae and subacicular hooks with light- to dark-brown cores and clear sheaths. Subacicular hooks bidentate. Both teeth directed distally; proximal teeth somewhat larger than distal teeth. UNKNOWN MORPHOLOGICAL FEATURES.—Many features from all parts of the body. EXPECTED STATES OF UNKNOWN MORPHOLOGICAL FEA- TURES.—None. CHARACTERS USED IN PREPARATION OF KEY NOT SCORED.—Inappropriate Characters: 22, 34, 39, 40 Unknown Characters: 4-19, 23-26, 28, 32, 42-50, 52, 54-60, 80-82. ASSUMED STATES FOR PURPOSE OF PREPARING KEY.— None.
