narrower one the seventh above, by its anterior third. Inferior labials 

 seven, the fourth mucli the largest ; the first of opposite sides separated by 

 the symphyseal. Postgeneials shorter than pregeneials. Frontal with 

 produced posterior angle ; parietals elongate. Gastrosteges 148 ; anal 

 1-1 ; urosteges 57. 



Color very pale brown above, white below. Top of head black ; a 

 broad black collar incomplete below, and connected with the head color 

 on the middle line. A white spot on labial below nostril ; another below 

 and behind orbit, which extends to the last superior labial, and connects 

 with the pale collar. Edges of scales on sides, brown-dusted. 



Total length 285 ; of tail 65mm., or a little less than one-fourth the 

 total. One specimen.

40. Aporophis almadensis Wagl. Abundant. 



41. OpHEOMORPHUS BRACHYURU3, Sp. nOV. 



Form robust, tail remarkably short, constituting less than one-sixth the 

 total length. Head wider than the neck, muzzle rather short. 



Rostral plate rounded, visible from above. Internasals as long as pre- 

 frontals, the median sutures of both not continuous, but each oblique to 

 the middle line. Frontal narrowing behind ; the parietals not longer than 

 the frontal, eraarginate at the point of union posteriorly. Loreal plate 

 much higher than long. Preocular narrow, not or barely reaching fron- 

 tal. Postoculars two, the inferiors quite small. Temporals 1-3. Supe- 

 rior labials eight ; the third uarrowed ; fourth and fiftli entering orbit ; 

 the last three large, the seventh higher than long. Inferior labials ten, 

 sixth largest. Geneials unequal, the posterior pair short. Scales small, 

 poreless, in 19 longitudinal rows. Gastrosteges 15-5 ; anal 1-1 ; urosteges 

 39. Measurements, No. 1, total length 371mm. ; tail 55mm. ; No, 2, 

 total 435 mm. ; tail 67mm. 



Color, above bright green ; below pale yellow. No markings. On the 

 superior labial plates the green and yellow piss into each other. 



This species is allied to the Opheomorphm typhlas, but has a relatively 

 much shorter tail. It is a much more robust snake than the 0. jcegeri 

 and it does not possess the brown dorsal stripe of the latter. 



Two specimens. 



42. OpaEOMORPHtJS MELEAGRis Shaw ; subsp. DOLiATUS Wicd. 



A large specimen in the which the black annuli are so wide as to nearly 

 meet on the dorsal region, leaving only traces of the ground color between 

 them. I have often had occasion to observe that this annulate coloration 

 characterizes adults as well as young.
