1036 MR. G. A, BOULENGER ON 



posterior and in contact with the syinphysial. Scales in 15 rows. 

 Ventrals 135-141 ; anal divided; subcaudals 56-59. Dark brown 

 above, scales edged with black ; a large yellowish spot on the 

 upper lip behind the eye, and a yellowish occipital bar encroaching 

 on the posterior pai-t of the parietal shields ; gular region white, 

 rest of lower surfaces bright coral-red. 



Total length 275 mm. 



Two specimens, male (V. 135 ; C. 59) and female (Y. 141 ; 

 C. 56). 



Very closely allied to H. alticola BIgr., from Santa Rita, noi'th 

 of Medellin, Colombia (9000 feet), but eye larger and frontal a 

 little longer in proportion to its width. 



37. Stenorhina degenhardti Berthold. 



38. Elaps corallixus L. 



39. Elaps rosenbergii Blgr. 



I have examined several specimens from various localities in 

 N.W. Ecuador, and also one obtained by Mr. M. G. Palmer at 

 Tado, Choco. 



40. Elaps microps, sp. n. (PI. CVIII. fig. 2.) 



Eye extremely minute, barely one-fourth as long as its distance 

 from the mouth. Rostral broader than deep ; frontal a little 

 broader than the supraocular, once and one-third as long as 

 broad, as long as the prsefrontals, half as long as the parietals, 

 which are longer than their distance from the internasals ; one 

 prse- and two postoculars ; temporals 1 + 1 ; seven upper labials, 

 third much longer than fourth, third and fourth entering the eye, 

 the latter very narrowly ; four lower labials in contact with the 

 anterior chin-shields, which are as long as the posterior. Scales 

 in 15 rows. Yentrals 205; anal divided; subcaudals 20. Tail 

 ending obtusely. Black above, with 46 narrow white, black- 

 spotted cross-bars ; these widen on the belly, which is barred 

 black and white ; an orange band across the head, from between 

 the eyes to near the end of the parietal shields ; tail orange-red, 

 with a black I'ing and a black terminal spot surrounding a small 

 white spot. 



Total length 650 mm. ; tail 25. 



A single female specimen. 



This new Elaps resembles strikingly E. mipartitus D. <fe B. in 

 the coloration, but is well distinguished by the much smaller eye 

 and by the proportions of the head-shields. 



41. Leptognathus spurrelli, sp, n, (PI. CVIII. fig. 3.) 



Body very slender, strongly compressed. Eye large. Rostral 

 small, about once and a half as broad as deep, not visible from 

 above ; internasals one-third the length of the prsefrontals ;
