shields on each side, separated from the lower labials. General 

 form slender ; limbs quite weak, not meeting when adpressed. 

 Scales in. thirty-six longitudinal rows ; each with a strong median 

 keel, and weaker ones on each side of it ; the median keels are 

 strong and continuous from the nape, becoming stronger pos- 

 teriorly, especially on the tail, whose superior and lateral surfaces 

 are thus thrown into gutters ; the keels form oblique lines over the 

 sides ; they are strong on the hinder and weaker on the anterior 

 limbs. Ground-colour grey, nape and back crossed by seventeen 

 brown cross-bands, which are nearly in contact medially and taper 

 to disappearance on the upper pa7-t of the sides ; their dorsal portions 

 sometimes confluent longitudinally ; below white, with a few scales 

 here and there brown. From snout to vent 90 millim.

6. Diploglossus phoxinus. 



Celestus phoxinus, Cope, Proc. Ac, Philad. 1868, p. 125. 



A fusiform species, the body rather stout and flattened, with 

 the outlines tapering gradually to end of snout and tail ; dorso- 

 lateral angle strong on scapular region. Head flattened, with 

 strong canthus rostralis and concave loreal region ; head-shields as 

 in D. occidiiHS. Fortj'-one or forty-two scales round the body, 

 dorsals strongly striate but not keeled. The limbs, when pressed to 

 the sides, fail to meet. Tail slightly compressed. Above light grey ; 

 sides from orbit to groin dark brown, with regular vertical brown 

 bars, which are margined behind by a close series of light spots ; two 

 series of small brown spots on each side of the dorsal region, the

Although very closely allied to 7). occiduus, this species may bo 

 distinguished by the following characters: — 8nout more depressed; 

 ear-opening considerably smaller ; oceii)ital not larger than inter- 

 parietal ; the diff'ercnce in the length of the third and fourth toes 

 very slight ; forty or forty-two scales round the middle of the body.
