cent occurrence of _C. mexicana_
known to me is from Las Vigas, Veracruz. As far as I know the species
has not previously been recorded from the Pleistocene.

Stirton (1930:225), in summarizing the group characters of Recent
Soricidae, listed the bicuspid talonid of m3 as one of the characters
of the "_Blarina_ group," which includes _Neomys_, _Soriculus_,
_Notiosorex_, _Chimarrogale_, _Cryptotis_, and _Blarina_. That this
character does not obtain universally within the group is demonstrated
by the unicuspid structure of the talonid of m3 of the majority of the
species of Mexican _Cryptotis_.

I am grateful to Drs. David E. Johnson and Henry W. Setzer
of the United States National Museum, and to Dr. John
Aldrich and Miss Viola S. Schantz of the United States Fish
and Wildlife Service for permitting me to examine specimens
in their care. Also I am obliged to Professor E. Raymond
Hall for permission to study the specimens from San Josecito
Cave. The late Professor Chester Stock intrusted the
specimens to Professor Hall for study and description.
