s, by Wm. Lloyd in September, 1887. Later, Allen wrote (Bull. Amer.
Mus. Nat. Hist., 5:200, August 18, 1893) that a series of moles from
Rockport, Aransas County, Texas, agreed essentially with the type. True
(Proc. U. S. Nat. Mus., 19:22, December 21, 1896) believed that the
type was actually from Aransas County rather than Presidio County. This
belief was shared by later workers. In checking the literature, I find
that the collector of the type, Wm. Lloyd, who was obtaining specimens
for George B. Sennett at the time, took other mammals in September as
well as in October of 1887 in Presidio County (see Allen, Bull. Amer.
Mus. Nat. Hist., 3:221, 223, 224, April 29, 1891) and birds there in
June of 1887 (see Sennett, Auk, 5:43, January, 1888). I can find no
evidence that Lloyd collected in or near Aransas County in 1887 and see
no reason for doubting that the locality, Presidio County, as written
on the original label of the type of _S. a. texanus_ is correct. Mr. M.
J. Carroll of the Texas State Historical Association advises me that in
1887, Presidio County was reduced to its present size by the creation
of Brewster and Jeff Davis counties. Lloyd might have taken the mole in
any one of these three Trans-Pecos counties. Even so, these counties
are widely separated geographically from the range of other moles
designated as _S. a. texanus_ (see Davis, Amer. Midl. Nat., 27:386,
March, 1942). The taking of _S. montanus_ in the Sierra del Carmen
immediately south of Trans-Pecos Texas leads me to think that Lloyd's
mole might have been taken in a mountainous region within one of the
three counties mentioned above. A description of _Scalopus aquaticus
texanus_ Allen follows:

=Scalopus aquaticus texanus= Allen

_Scalops argentatus texanus_ Allen, Bull. Amer. Mus.
Nat. Hist., 3:221, April 29, 1891.

_Type._--Sex unknown, adult, skin no. 3488, skull no. 2740,
Amer. Mus. Nat. Hist.; Presidio County, Texas; September,
1887, obtained by Wm. Lloyd.

_Range._--Limits of range in Trans-Pecos Texas unknown.

_Diagnosis._--Size small; rostrum heavy and broad; lower
jaws heavy; palatine space wide with upper tooth-rows arched
laterally; teeth large, especially fourth premolar and
molars.

_Comparison._--From adults of comparable age from Rockport,
Aransas County, Texas, _S. a. texanus_ differs in: Rostrum
broader and heavier; lower jaws heavier; palatine s
