" Iris orange, bill dark greenish shite, feet olive green."<br />
The detailed measurements <strong>of</strong> two males from Terutau,<br />
taken in <strong>the</strong> flesh are : TL.<br />
287, 290 ; W,<br />
164. 157 : T.<br />
97, 95 ;<br />
B, 50, 54; TS. 31,28.<br />
The wing and bill (from gape) <strong>of</strong> <strong>the</strong> Langkawi specimens<br />
taken on <strong>the</strong> skins are male, W, 156, B. 55; Female, W, 151,<br />
B. 49; <strong>of</strong> three o<strong>the</strong>r specimens from Terutau:— Males, W.<br />
159, 154, B. 52, 51. Female, 153, B. 46. Of <strong>the</strong> Trang specimens,<br />
Male, W. 157, B. 49; Female, W. 150, B. 51. Of<br />
<strong>the</strong> bird from Koh Samui, W. 160, B. 52. The dimensions <strong>of</strong><br />
two males from Tonka (<strong>the</strong> type locality <strong>of</strong> <strong>the</strong> subspecies as<br />
given by Hume {Stray Feath. viii, p. 154* as 6-15 and 6-3 in.<br />
on <strong>the</strong> wing. viz. 156 and 160, which agrees well with <strong>the</strong><br />
above series.<br />
In my paper on <strong>the</strong> collection made by Mr. Kloss in S. E.<br />
Siam I unfortunately attributed Tickell's type <strong>of</strong> Picus<br />
guttacristatus (Journ. Asiat. Soc. Bengal) lii, p. 578 (1833) to<br />
Nor<strong>the</strong>rn Tenasserim, where <strong>the</strong> greater part <strong>of</strong> his collections<br />
were made, whereas it was really secured in <strong>the</strong> jungles <strong>of</strong><br />
Eastern Bengal. As Hume, Oates and Blanford have pointed<br />
out <strong>the</strong> Sou<strong>the</strong>rn Indian bird, C. delessertii, Blyth, that from<br />
eastern Bengal and <strong>the</strong> low country adjacent, C. guttacristatus<br />
(Tick.) and <strong>the</strong> birds from <strong>the</strong> nor<strong>the</strong>rn <strong>Malay</strong> Peninsula<br />
approximate in size, though it would appear that <strong>the</strong> <strong>Malay</strong><br />
birds on <strong>the</strong> whole averages smaller, <strong>the</strong> wing never exceeding<br />
164 mm (6.45 in.) while it is possibly brighter in general tone.<br />
Chrysocolaptes sultaneus (Hodgs.) from <strong>the</strong> Himalayas is a<br />
very large bird indeed and can fairly claim subspecific rank on<br />
<strong>the</strong>se grounds alone though <strong>the</strong>re are no tangible differences in<br />
colouration.<br />
In tlie <strong>Malay</strong> Peninsula <strong>the</strong> bird is common in <strong>the</strong><br />
nor<strong>the</strong>rn third but is unknown from any locality between<br />
Penang and Sou<strong>the</strong>rn Johore where a small form occurs, W.<br />
male, 148, 143; B. 46, 47, which will receive a name in due<br />
course. This form also occurs abundantly on <strong>the</strong> islands <strong>of</strong><br />
<strong>the</strong> Rhio-Johore archipelago south <strong>of</strong> Singapore.<br />
It thus appears that in order <strong>of</strong> size we have <strong>the</strong> following<br />
forms.<br />
C. guttacristatus sultaneus, Himalayas. Wing averaging<br />
177 mm.<br />
C. guttacristaius guttacristatus. Eastern Bengal,<br />
Burma, etc. Wing 161 or perhaps slightly more. •
