MEXICAN HERPETOLOGICAL MISCELLANY—SMITH 377 
Color.—Dorsal color dark gray; sides of head darker, with vague 
light areas; a dark stripe through upper temporal region; dark marks 
on labials, mental and chinshields as in dontomasi; a body pattern 
faintly discernible, similar to that of dontomasi. 
Remarks.—This species is obviously a close relative of dontomasi; 
it is with some hesitation that I have held the present specimen as dif- 
ferent from the other two. The differences between radula and donto- 
mast are rather striking, however, in scutellation of the body, as can 
be seen by a comparison of the diagnoses of the two. 
LEPIDOPHYMA SMITHIL TEHUANAE, new subspecies 
Holotype—vU.S.N.M. No. 111488, from Cerro Arenal, 30 kilometers 
west of Tehuantepec, Oaxaca.

tepec, Oaxaca; and U.S.N.M. No. 48105, mountains near Santo 
Domingo, Oaxaca. 
Diagnosis —Three dorsal and two ventral whorls of small scales 
separating the whorls of enlarged scales on tail; femoral pores 13 or 
less; no median frontonasal; very young with pink tails. 
Description of holotype-——Head scutellation typical, except: No 
median frontonasal; anterior of the three enlarged temporals small, 
separated from labials by a narrow row of granules and a row of 
somewhat enlarged scales; scales in posterior temporal region ir- 
regularly enlarged, some of the larger ones arranged in a diagonal 
row a little in front of ear; no enlarged scales adjoining enlarged 
temporals; auricular lobules prominent; granules in gular region 
relatively large, about nine in the vertical diameter of ear opening 
(at about middle of throat). 
Enlarged tubercles on sides of body flattened on their posterior 
faces, arranged in vertical rows in which seldom more than two of 
the tubercles are separated on both sides from the adjacent enlarged 
tubercules; generally four rows of granules middorsally between para- 
vertebral rows of enlarged tubercles. 
Ten longitudinal rows of ventrals, 37 rows from gular fold to 
anus; 9-10 femoral pores; 75 mm. snout to vent. Three rows of 
small, keeled scales dorsally on tail, separating the whorls of en- 
larged scales; scales of whorl following the whorl of enlarged scales 
much reduced in size toward base of tail, proportionately equal to 
others only distal to about middle of tail; the latter whorl is dropped 
on the ventral! surface, leaving 3 whorls to a segment.
