labials; chin-shields very large, one anterior and three pairs, the 
first two pairs in contact; gular scales equal, lanceolate-triangular, 
strongly keeled and imbricate, arranged in obliqne rows. Dorsal 
scales very large, those on the middle of the back largest and their 
exposed portion as broad as long, all very strongly imbricate, leaf- 
shaped, ending in a sharp point, and very strongly keeled; on the 
hinder part of the back the keels become continuous, forming ridges 
which become most conspicuous on the tail. The ventral scales 
similar to the dorsals, but very feebly keeled and arranged in longi- 
tudinal and transverse series. Eighteen to twenty scales round the 
middle of the body ; twenty-one to twenty-four scales from occiput 
to sacrum inclusive ; twenty-five or twenty-six from chin-shields to 
preanals. Latter, four anterior and four posterior, all keeled, the 
postero-median pair largest. Limbs with large imbricate keeled 
scales. Males with sixteen to eighteen femoral pores on each side. 
Tail with large keeled imbricate scales, largest on the upper surface, 
where the keels form four strong, longitudinal, slightly denticulated 
ridges. Brown above, yellowish on the upper surface of the head 
and nape ; back indistinctly variegated with darker and lighter ; tail 
with yellowish dark-edged spots, having a tendency to form rings ; 
lower surfaces yellowish white; labials and chin-shields brown-

Lepidosoma carinicaudatum, Cope, Journ. Ac. Philad. (2) viii. 1876, 
p- 160 
This species is probably closely allied to the preceding, but, judging 
from Cope’s description, must be considered distinct. The limbs are 
shorter ; the temporal scales are smooth, atleast anteriorly ; twenty- 
one scales round the body; an oval median anterior preanal, instead 
of apair; eleven femoral pores on each side. The coloration is very 
different :—Colour above cinnamon-brown, below yellow; sides, 
from ear to an indefinite point on the tail, black, inclosing a narrow 
yellow band from axilla to groin; black on scapular region, pale-
