transverse series of larger tubercles on its back. Underside 
with small imbricate scales. Neither preeanal nor femoral 
pores. 
Parcedura sancti johannis. 
Limbs rather slender. Head large, depressed, with the 
snout of moderate length. A scries of large tubercles along the 
superciliary margin and across the temple. A pair of chin- 
shields, which are much longer than broad. Ear-opening 
vertical, narrow. Brownish, marbled with darker 5 a black 
spot on the occiput. Lower parts whitish. 
A single specimen was obtained, 4^ inches long, of which 
the tail takes 2 ^ inches; distance from the snout to the ear¬ 
opening 8 | lines ; length of fore leg 11 lines ; length of hind 
leg 15 lines. 
Lycodryas, g. n. Lycodont. 
Body slender and compressed, with the abdomen angular 
on the sides. Scales smooth, in nineteen rows, those of the 
back not conspicuously enlarged. Anal bifid ; subcaudals 
bifid (partly simple). Eye with vertical pupil. Two nasals, 
the nostrils in the anterior; one loreal, not reaching the orbit. 
Anterior maxillary and palatine teeth longest, followed by 
other long teeth, which gradually decrease in length. 
This genus is allied to Hormonotus and Tetrarjonosoma , but 
differs from the former in the scutellation of the side of the 
head, and the absence of large dorsal scales ; from the latter 
also in the scutellation of the head, and, besides, in the 
dentition. 
Lycodryas sancti johannis. 
Head depressed, of moderate length, with rather broad 
snout, and very distinct from the very slender neck. Body 
and tail very slender, with an obtuse keel on each side of the 
abdomen. Eye of moderate size, with vertical pupil. Ros¬ 
tral broad, low, not extending to the upper surface of the 
snout. Anterior frontals about one third the size of the pos¬ 
terior. Vertical broad, but longer than broad, with parallel 
lateral edges. Occipitals pointed behind. Two small nasals, 
the anterior pierced by the nostril. Loreal long. Prmorbital 
broadly in contact with the vertical. Three postoculars. 
Nine upper labials, the fourth and fifth and sometimes the 
third entering into the orbit; the sixth is small and trian¬ 
gular, in contact with the lower postorbital; the three pos¬ 
terior arc low. Temporal scales rather irregular and 
numerous.
