is darker on tlie largest specimen ; the light spots of the back continue 

 beyond the base of the tail ; but anteriorly the ground color has become 

 so dark that the spots and bands are obscured. 



Hallowell's specimens, from Jamaica, were "uniform brown above 

 with no lines or spots." The circular pupil and the clawless thumb were 

 probably oversights. Such measurements as he gives would make his 

 types smaller than the largest described above. Dr. Boulenger's descrip- 

 tion, also taken from Jamaican specimens, answers much better to those 

 from Grand Cayman. 



Alsophis caymanus. 

 A. angulifer Bibr. ; Cope, var. n. 



Body moderate, blunt-angled at the edge of the abdomen ; head dis- 

 tinct, narrowed in front, subquadrangular in transverse section, flattened 

 on the crown ; tail nearly one-third of the total length, slender. Eye 

 moderate. Teeth small, longer and farther apart backward. Scales with 

 two pores, smooth, in seventeen rows ; dorsal longer than broad, outer 

 and caudal as broad as long. Ventrals broad ; in five specimens they 

 number 167, 170, 171, 173, and 175 respectively. Anal bifid. Subcau- 

 dals in two series ; in three specimens there are 125, 127, and 129 pairs. 

 Crown-shields nine ; internasals moderate, narrower forward ; prefrontals 

 broader than long, bent downward, and shortened, at the loreal ; frontal 

 about twice as long as broad, truncate in front, narrower and having par- 

 allel sides behind the middle, acute-angled between the parietals ; supra- 

 oculars large, broad posteriorly ; parietals very large, outer anterior angle 

 in contact with the lower postorbital. Rostral medium, hardly reaching 

 the top of the snout, in contact with six plates. Nostril between the 

 quadrate halves of the small nasal. Loreal small, quadrangular, hinder 

 lower angle acute. One anteorbital, reaching the top of the head, not in 

 contact with the frontal. Two postorbitals ; lower in contact with the 

 fifth and sixth labials and the temporal ; upper meeting the supraocular 

 and the parietal. Temporal large, narrow anteriorly, bounded by the 

 lower postorbital, the posterior three labials, and two post-temporals. Of 

 the latter the upper is the larger. Labials eight, third, fourth and fifth in 

 orbit, sixth and seventh very large. Lower labials ten, first pair meeting 

 behind the mental, first six in contact with the submentals, fifth and sixth 

 largest. Mental small, triangular. Submentals two pairs, posterior much 

 longer, each of the anierior meeting five, and each of the posterior meet- 

 ing two of the lower labials. 



Large specimens have a ground color of reddish brown, and the greater 

 number of the scales black-edged or black-tipped ; backward they have 

 irregular spots of dark including one to several scales ; and the belly ap- 

 pears to have been a brick-red in life. The larger ones have transverse 

 blotches of brown under the tail, and numerous white-edged scales similar 

 to those of Liophis cobella. Some have vertical bands or blotches of brown 

 anteriorly on the flanks ; farther back these meet on the vertebral line and 

 become transverse bands.
