Two male specimens from a ravine near Mesquititlan, north of 
Chilpancingo, Guerrero. 
This very remarkable species, which I take the liberty of naming 
after Mrs. Gadow, agrees with S. pyrrhocephalus Cope, in its 
distinctly compressed tail, but differs from it in having much 
smaller scales and more numerous femoral pores. No species of 
Sceloporus was hitherto known to have more than 25 femoral pores 
on each side. 
LEPTODIRA GUILLENI. (Plate VII. fig. 2.) 
Rostral twice and a half as broad as deep, scarcely visible from 
above; internasals a little longer than broad, little shorter than 
the preefrontals; frontal once and two-thirds as long as broad, a 
little longer than its distance from the end of the snout, a little 
shorter than the parietals; loreal as long as deep; one preocular, 
well separated from the frontal; two postoculars; a subocular 
below the preocular and another below the postoculars ; temporals 
142; eight upper labials, fourth and fifth entering the eye; five 
lower labials in contact with the anterior chin-shields, which are 
much shorter than the posterior. Scales in 23 rows. Ventrals 
189; anal divided; subcaudals 71. Above with eleven dark 
brown areas separated by narrow greyish-white bands; snout, 
interocular region, and temples brown, back of head and nape 
bright red with a dark brown median line; a light, dark-edged 
streak along the upper lip; lower parts white, the ventrals with 
a brown spot on each side; subeaudals brown, edged with whitish. 
Total length 530 millim.; tail 110. 
A single female specimen from the Rio Balsas, Guerrero. 
This species which, on the whole, is intermediate between 
L. nigrofasciata Gthr. and L. personata Cope, is named after 
Senor Don Manuel Guillen, Governer of the State of Guerrero, in 
recognition of valuable assistance rendered to Dr. Gadow.
