pace
wider, with upper tooth-rows more arched laterally;
individual teeth in both jaws larger, especially fourth
premolar and molars. From _S. a. intermedius_, which is
geographically nearest to the northeast (adult specimens
from Meade, Clark and Barber counties, Kansas, and Dewey
County, Oklahoma), _S. a. texanus_ differs in: Size smaller;
rostrum less massive and shorter; tooth-row shorter.
_Remarks._--The type has been previously examined by True (_op.
cit._:44). The skin is faded and of little taxonomic worth. The
anterior part of the skull is present along with both upper tooth-rows
and most of the lower jaws. The teeth are well worn, indicative of old
adulthood. In size, _S. a. texanus_ appears closest to moles from
southern Texas (Rockport) which previously were assigned to the
subspecies _Scalopus aquaticus texanus_. The tooth-rows are of the same
length, but the individual teeth of _S. a. texanus_ are significantly
larger.
The moles in southern Texas previously ascribed to _Scalopus aquaticus
texanus_ seem to be without a name and may be known as follows:

_Diagnosis._--Size small; according to Davis (_loc. cit._),
"... length of hind foot seldom more than 19 mm.; total
length seldom more than 140 mm. Skull small and flat, seldom
exceeding 33 mm. in occipitonasal length and seldom
equalling 10 mm. in depth; maxillary breadth usually less
than 10 mm.; alveolar length of maxillary tooth row seldom
more than 10.5 mm."
_Comparison._--From _S. a. cryptus_, geographically adjacent
to the east, _S. a. alleni_ differs in: Size smaller; color
paler; skull smaller and flatter. From _S.
