ART. 11 HERPETOLOGICAL COLLECTIONS FROM SIAM — COCHRAN 25 



The Bangkok specimen, No. 72051, is an adult measuring 531 mm. 

 in length, the tail measuring 88 mm. In coloration it agrees well with 

 Dr. Malcolm Smith's description of typical Siamese specimens.^ 



The snake from Koh Tao, No. 72308, is a young one, agreeing in 

 every respect with the above, excepting that the light blotch on either 

 side of the occiput is less invaded by the dark brown of the body 

 color. Regarding this individual the collector has noted : "Black and 

 light green; labials white, with black spots in definite series; top of 

 head black." 



[75686. Markings on nape side of head and along jaws pale yellow; 

 a bright yellow line along upper jaw from eye to end of snout; back 

 dull blackish brown with whitish markings, top of head reddish brown, 

 belly white.— H. M. S.] 



LYCODON LAOENSIS Gunther

 72317 (S2930) Bandon Jan. 7, 1927. 



This individual has 17 scale rows, 167 ventrals, a divided anal, 64 

 caudals, 9 upper labials, oculars 1+2 and temporals 2 + 3. It is to 

 be noted that the lowest number of ventrals hitherto recorded for 

 this species is 175. The coloration of my specimen corresponds to 

 the figure (Cat. Snakes Brit. Mus., vol. 1, 1893, pi. 24, fig. 3), except 

 that the white bands are very much more distinct and less invaded 

 with dark pigment.

76858 (S4144) do Dec. 22, 1928. 



This snake is apparently quite rare, as Dr. Malcolm Smith lists 

 only two specimens of it taken in Bangkok. The earlier specimen 

 collected by Dr. H. M, Smith is larger than those previously recorded. 

 It measures 825 mm., of which the tail comprises 178 mm. The 

 scale formula is given: 13 rows around the body; 254 ventrals; an 

 undivided anal; 95 caudals; 7 labials; 1 loreal; no preocular; 2 postoc- 

 ulars; on one side of the head a single anterior temporal, and two 

 anterior temporals on the other side ; two posterior temporals on both 

 sides. The coloration is exactly as given by Boulenger, except that 

 there are brown spots behind the eyes extending over the anterior 

 temporals. The latter specimen, a very young one, has 13 scale rows; 

 253 ventrals ;1 anal; 102subcaudals; 1 loreal; no preocular; 2 postocu- 

 lars; temporals 1+2.
