shields on each side, separated from the lower labials. General 
form slender; limbs quite weak, not mecting 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 part 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. Ae. 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. occiduus. Forty-one or forty-two scales round the body, 
dorsals strongly striate but not keeled. The limbs, when pressed to 
the sides, failto meet. Tailslightly compressed. Above light grey ; 
sides from orbit to groin dark brown, with regular vertical brown 
bars, which are margined behind by aclose series of light spots; two 
series of small brown spots on each side of the dorsal region, the 
median stronger on the nape, all vanishing behind; limbs with 
brown light-edged cross-bars; below immaculate. From snout to 
vent 83 millim.

Rept. p. 385, pl. xxii. fig. 2. 
Although very closely allied to D. occiduus, this species may be 
distinguished by the following characters :—Snout more depressed ; 
ear-opening considerably smaller; occipital not larger than inter- 
parietal ; the difference in the length of the third and fourth toes 
very slight; forty or forty-two scales round the middle of the body.
