NATURAL HISTORY SOCIETY’S SNAKE COLLECTION. 
BY 
Cot. F. Watt, I.M.S., C.M.G., C.M.Z.S. 
(With a plate.) 
Our Society is indebted to Mr. P. R. M. Leonard for some valuable snakes 
collected at Sinlum Kaba, Burma, Lat. 24” Long, 97° at an elevation of 6,000: 
feet :—These include the following :— 
Typhlops diardi Schlegel. 
One typical mature specimen. 
Cylindrophis rufus (Laurenti). 
One halfgrown@ ? Ventrals 202. Subcaudals 5 on the right, 6 on the left 
side ; the 2nd and 3rd entire. 
Tropidonotus parallelus Boulenger. 
An immature specimen 289 mm. (112 inches) long. Ventrals 160. Subcaudals 
83. Maxillary teeth 22 ? Syneranterian, coryphodont. 
Amphiesma himalayana (Gunther). 
Two small specimens, one 292 mm. (114 inches) and the other 222 mm. (8? 
inches). Both quite typical. 
Trirhinopholis nuchalis Boulenger. 
One specimen 298 mm. (113 inches) long. The tail 28 mm. (13 inches). 
Costals 15 in the whole body length. Ventrals 126. Anal _ entire. 
Subcaudals 21, the 2nd to 7th entire. The loreal is absent. (Possibly confluent 
with the posterior nasal?) Labials 5, the 3rd only touching the eye. (The 
3rd is long and appears to be a confluence of the normal 3rd and 4th.) The 
nostril is placed equally in both nasals, and occupies the upper three-fourths 
of the suture, so that the generic name is not at all appropriate. Light brown. 
above, most scales finely bordered with black, thus producing a reticulate 
pattern. The belly is pale yellow (white ?) with many, scattered, very small 
blackish spots. The sagittal mark on the nape is conspicuous. 
Zaocys nigromarginatus (Blyth). 
One fine adult. Ventrals 196. Subcaudals 130. 
Coluber leonardi, spec. nov. 
Lenght 279 mm. (11 inches). Tail 41 mm. (12 inches). Costals two head- 
lengths behind head 19, midbody 19, two head-lengths before vent 17 ; 
smooth, with double apical facets. Ventrals 223 ? (damaged). Anal. Divided. 
Subcaudals 53, divided. Rostral. Touches six shields ; the internaso-rostral 
sutures longer than the naso-rostral, and naso-labial, half that between the pree- 
frontals, less than both taken together. Internasals. Two ; the suture between 
them less than one quarter the internaso-prefrontals. Prafronials. Two; the 
suture between them subequal to the prefronto-frontals. Frontal. Touches six 
shields, the supraocular sutures rather longest ; length equal to snout, two- 
thirds the parietals. Supraoculars. Equal to the prefrontal and internasal, 
rather less than the frontal, three-fifths the parietals, rather greater than the 
anterior temporal. Nasals. Touching Ist and 2nd supralabials. Nostril wholly 
in the anterior shield, and occupying the median two-fourths of the suture. 
Loreal. Absent. Preocular, One. Postoculars. Two. Temporals. 1+2 ; 
the anterior touching the 5th and 6th supralabials. Swpralabials 7 ; the 8rd.
