60 BULLETIN 133, UNITED STATES NATIONAL MUSEUM blue heron. They were seen in flight to various feeding grounds at dusk. At a large lagoon at Kilometer 110 they were fairly common and were encountered among rushes, from which they flushed with a low note that resembled took xook. In the Guarani language the species was known as hoc.6. The adult was called nhe ha na by the Anguetes, while the bird in barred immature plumage was known as ca pi a tik. IXOBRYCHUS INVOLUCRIS (Vieillot) Ardea involucris Vieillot, Eucyc. Meth., vol. 3, 1823, p. 1127. (Paraguay.) Azara's least bittern is similar in haunt and habit to the least bittern of the West Indies and the United States, so that it may be more common than would appear from the few occasions on which I encountered it. On October 31, 1920, at the Estancia Los Yngleses, near Lavalle, Buenos Aires, while wading about in water nearly to my knees, I saw three among rushes in a caiiadon. The birds were wild, flushed at a distance of 60 meters, and flew rapidly away above the marsh vegetation, to drop down again when at a considerable dis- tance away. A male was killed at long range on this date and one was taken on November 2. Another was seen November 9, The birds appear light in color when flying and are of surprisingly rapid flight for a bird of this group. At Carhue, Buenos Aires, one flushed from a clump of cattails in an arroyo on December 15 and one was seen the following day. One was recorded at the Laguna Castillos, south of San Vicente, Uruguay, on January 31, 1921. Family CICONIIDAE JABIRU MYCTERIA (Lichtenstein) Ciconia mycteria Lichtenstein, Abhaudl. Kon. Akad., Wiss. Berlin (Phys. Klass.) for 1816-17, 1819, p. 163. (Brazil.) At the Eiacho Pilaga, Formosa, two jabirus were seen on August 16, 1920, as they soared at least 1,000 meters above the earth. The birds, in appearance snow white with dark heads, turned in short circles with set wings, and finally sailed away out of sight. At Puerto Pinasco, Paraguay, on September 3 one passed high overhead. I had no other opportunity to observe this species. MYCTERIA AMERICANA Linnaeus Mycteria americana Linnaeus, Syst. Nat., ed. 10, vol. 1, 1758, p. 140. (Brazil.) On November 16, 1920, a flock of 12 wood ibis was noted between Lavalle and Santo Domingo, Buenos Aires; the species was seen nowhere else in Argentina. At the Laguna Castillos, below San
BIRDS OP ARGENTINA, PARAGUAY, URUGUAY, AND CHILE 61 Vicente, Uruguay, wood ibis were fairly common on January 31, 1921, and an immature male was taken. Here they ranged in bands of 10 to 20 individuals, often accompanied by a roseate spoonbill or two, that rested in open grassy areas adjoining shallow rush-grown lagoons. They were wary, but under cover of rushes I crept within 40 meters of one flock and lay for a time watching them as they rested motionless or preened their feathers. At a sudden alarm they rose in confusion, and I killed one that I had singled out in advance. When flocks were flushed they usually sailed and flapped for a time in narrow circles a hundred meters above the earth and then flew on to some safer resting place. On Februar}^ 2 a flock -uas observed in a baiiado near the Arroyo Sarandi; 30 miles northwest of San Vicente, and from February 6 to 9 scattered individuals were seen near Lazcano. The wood ibis was known locally as fraile. The specimen secured still shows traces of the nestling down on the nape and the back of the neck. In this species neck feathers of the Juvenal plumage often burst the sheaths near the base, while the tip is still inclosed in a corneous case so that the tips of the feathers appear as though waxed. EUXENURA GALATEA (Molina) Ardea Galatea Molina, Sags. Stor. Nat. Chili, 1782, p. 235. (Chile.) In Molina's account of the birds of Chile there are two composite names that refer in part to the present species and in part apparently to the egret {Gasmerodius) . The first of these, Ardea galatea (p. 235), is described as "di color di latte col becco giallo lungo quattro pollici, e le gambe crem fine ; queste gambe, come pure il collo, hanno due piedi, e sette pollici di altezza," while the Latin diagnosis, in a footnote, says "Ardea occipite subcristato, corpore lacteolo, rostro luteo, pedibus coccineis." The length of bill cited is too short for Euxenura and nothing is said of black in the wings, but in general color of feathers and legs and in size this can fit only the stork, and the name is here taken for that species, Tantalus pillus of the same work (p. 243) is also a composite, but here again general size and color of body are those of Euxenura^ while length of bill and color of legs are those of Gasmerodius. Both names seem more applicable to Euxenura and are here accepted for that bird, a course that obviates necessity for change in the name of the egret. The Maguari stork was common through the Chaco as far north as the Territory of Formosa, but was not observed in Paraguay. From Garabate, Santa Fe, northward to Charadai, Chaco, many were seen from the train on July 5, 1920. Single individuals were 54207—26 5
