MEXICAN AMPHIBIANS—TAYLOR AND ‘SMITH 543 
obtained in considerable numbers in stump holes that had filled with 
pine needles and loose earth. 
The distribution of this species is puzzling. It is known in the 
Ajusco range, Mount Popocatepetl, Mount Ixtaccihuatl, and the 
adjoining short range to the north. It is present, after a presumed 
hiatus, on the mountains of northeastern Puebla (north of Limén) and 
on Cofre de Perote. It appears to be absent on Mount Malinche 
(Malintsin). It has been taken on Mount Orizaba but not about the 
Cumbres of Acultzingo. It is apparently absent in the mountains 
to the north, in Hidalgo. Of course, its absence from the collections 
made in these localities is not conclusive evidence that it does not 
occur. However, where it is known to occur it is usually extremely 
common, and its habitat makes it especially easy to discover. In 
Hidalgo it is replaced by B. multidentata. Wehold as surely incorrect 
the locality data ‘“‘Tehuantepec”’ borne by U.S.N.M. No. 30347.

A large series of 108 specimens was collected in El Chico National 
Park, Hidalgo, on September 17, 1939, a part of which series bears 
U.S.N.M. Nos. 106324 to 106338. These were found under bark, un- 
der logs and rocks, as well as in bromelias growing on the trunks of 
the fir and pine trees. One female examined contains 11 large ovarian 
egos, 5 on one side, 6 on the other. 
In gravid females the adpressed limbs may merely touch or fail to 
touch by the width of a costal fold, while in males they usually overlap 
the width of a fold.
