Upper surface pale brown, with a longitudinal row of black spots 
in middle of back. A light lateral stripe from the supraorbital angle, 
along the parietal border and extreme edge of the dorial surface, to 
the tail. Sides of body black, variegated with blue or yellowish 
spots on the neck. Entire menta! region yellowish, without spots. 
A dark coloration predominates over the whole inferior surface of 
the throat (beginning from the last postrnentals), of the body, limbs, 
and tail. The scales are blackish at their root or for half their 
length, and yeJlowish at the tips. 
A single specimen from Canelos. 
This is a third species of the genus Lepomma^ bearing a resem- 
blance to L. carinkaudaium^ Cope, in the pointed and carinate scales, 
and also in the Inrge preeanal scuti-s, in which both species ditFer

I8G2 (1863)» pi. 2, fig. I. It has very much smaller scales, how- 
ever, than the former species, in all the specimens of which I count 
only nineteen round the body, while in the present there are not 
less than tbirty-fonr. This great difference is made by the scales 
on the sides being much smaller in the species under consideration, 
while m L, carinicaudatum they are uniform with those of the back. 
L, dinpar, recently described by Prof- Peters, is evidently cpnle dif- 
ferent, being more" nearly allied' to L, scincoides. 
Loxopholk nifficfps. Cope, must be a Lizard very similar to both 
of these species ; and I am unable to see how its scntellation differs 
generically from that of Lepo&oma as represented by i. carinicau- 
daium, in which Professor Cope describes ** four abdominal rows of 
scales wiih the keels reduced to an angle and mucro,** consequently 
smooth. The abdominal scales are (piadrate in the species which 
1 have now described ; and this character appears to be the only one 
that was left to the genus LocvophoHa when Prof. Cope described 
Lepoaoma earinicaudaturn. 
Having carefully compared the Lizard brought by Mr, Buckley 
from Ecuador with the description of Lojcophotu ntfficeps, I find 
that the intemasal plate is much longer in that sjtecies, tlie jirie- 
frontals more extensively in contact, and the scales much larger, 
being intermediate between those o( L.earviicaudatum and the present 
species (twenty-four round the middle of the body). Moreover the
