TWO :n'e\v riioGs from Mexico — taylor 45 



Measurements {in mm.). — Snout to vent, 33; snout to angle of 

 mouth, 7.6; snout, 5.1; eye diameter, 4; tympanum, 2.3; head width, 

 11.2; head length, 11.25; arm, 20.2; leg, 45; tibia, 14; foot, 21. 



Remarks. — The paratype is a very young specimen having the mode 

 of coloration somewhat different. The general coloration is blackish 

 brown, with the minute grayish-wliite flecks a little more prominent 

 on the sides. A row of white flecks is present along edges of Ups, 

 wliile the Hght flecks and spots on the arms are more pronounced, the 

 light predominating. On the limbs the whitish-cream coloration 

 covers most of the anterior face of the femur and a region on the dorsal 

 surface of the femurs. The banding is not pronounced on the postero- 

 dorsal face of femur and tibia. Numerous small cream spots are pre- 

 sent on cliin, breast, and abdomen, with a fine peppering of dark 

 pigment. 



Tliis species appears to be most closely related to the very much 

 smaller Syrrhophus guttilatus (Cope) (type locaUty, Guanajuato). It 

 difi'ers apparently in having shorter legs and longer arms and a totally 

 different coloration (that species being brown with whitish spots, the 

 hmbs banded with rufous). 



The specimens were collected 15 miles west of Galeana; elevation 

 5,200 feet. They were found in semiarid terrain, under a rock. The 

 vegetation is of low shrub, cactus, and agaves; no grass cover is present 

 in the type locahty. 



The species is named for its discoverer, Dr. Hobart M. Smith.

Diagnosis.' — A medium-sized tree frog (known maximum size 35 

 mm., snout to vent); fingers about one-third, toes about two-thirds,
