378 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 92 | 
Color.—Dark brown above, with small, light ocelli on body arranged 
in paravertebral, dorsolateral, and lateral rows on each side; belly 
unmarked; gular region feebly mottled; dark marks present in the | 
center of each chinshield (infralabial) and of mental. 
Variation —The femoral pores in the 8 adult paratypes vary from 
10 to 13 (10, 6; 11, 2; 12,5; 18,2). The 3 juveniles (largest 29 mm. 
snout to vent) had bright pink tails in life; after a year of preserva- | 
tion they appear of very light flesh color, with vague reticulations of 
dark pigment. 
All specimens lack a median frontonasal, and largely on the basis 
of this character the specimens from the Tehuantepec area are dis- | 
tinguished from typical sméthii. This scale is reguiarly present in | 
smithii, as shown by a large series of 127 specimens from various 
localities in southern Chiapas near Escuintla. The young smithii, | 
moreover, many of which were seen in life, do not have pink tails, but | 
rather the tails are dark, as are the bodies. 
LEPIDOPHYMA SMITHII OCCULOR, new subspecies 
Holotype-—U.S.N.M. No. 47138, from Jalpan, Querétaro, collected 
by Nelson and Goldman. 
Paratypes.—Two topotypes, U.S.N.M. Nos, 47184-47135. 
Diagnosis —Three dorsal and 2 ventral whorls of small scales sepa- 
rating the whorls of enlarged scales on tail; femoral pores less than 
14 (in known specimens, 10-11) ; no median frontonasal; young un- 
known; scales anterior to ear very small and uniform, except for a 
row of enlarged tubercles adjacent to enlarged temporals; whorls 
on tail relatively poorly differentiated; most of tubercles on sides 
of body separated from each other; about 12 granules near middle 
of throat contained in vertical diameter of ear opening. 
Description of holetype-—Head scutellation typical, except: No 
median frontonasal; anterior of the 3 enlarged temporals small, sep- | 
arated from labial by a single large scale nearly as large as labial; 
scales in front of ear (anterior to prominent auricular lobules) very | 
small and even in size, except for a row of enlarged ones adjoining 
the enlarged temporals; granules in gular region very small, about 
12 (at middle of throat) in the vertical diameter of ear opening. 
Enlarged tubercles on sides of body flattened on their posterior 
faces, arranged in vertical rows in which practically all the enlarged 
tubercles are separated from each other; generally five rows of gran- 
ular scales middorsally between paravertebral rows of enlarged scales. 
Ten longitudinal rows of ventrals; 37 rows from gular fold to anus; 
10-11 femoral pores; 93 mm. snout to vent. | 
Three whorls of small, keeled scales dorsally on tail, separating the 
whorls of enlarged scales; scales of whorl following the whorl of
