Jackson—New Moles of the Genus Scalopus. 
21 
general characters most nearly like Scalopus a. iutermedius, but much 
paler and lacking ochraceons suffusion on nose and wrists; slightly smaller 
than intermedins, with skull actually shorter and relatively broader 
through mastoids. 
Color. —In autumn pelage: back light drab slightly tending towards 
avellaneous, becoming lighter on head and shading in some cases into 
ivory yellow on nose; uuderparts much the same color as hack, more 
mixed with neutral gray and occasionally washed with Saccardo’s umher 
or cinnamon-hrown. 
Measurements. —Type, measured iu the flesh: total length, IGO; tail 
vertehne, 31.5; hind foot, 32. Skull of type: coudylohasal length, 33.9; 
greatest length, 34.0; palatilar length, 14.2; breadth across mastoids, 
17.9; interorbital constriction, 8.2; maxillary tooth row, 11.1; mandi¬ 
bular molar-premolar row, 10.9. 
Remarks. —This form can be readily distinguished from all other moles 
wth which it is likely to be confused by its pale color and lack of 
ochraceons suffusions. It appears to be the mole of the northern j)lains 
region from Kansas north to northern Nebraska, and from central Ne¬ 
braska west to eastern Colorado. 
Scalopus inflatus sp. nov. 
Type, young adult, sex unknown, skin and skull. No. 52,709, U. S. 
National Museum, Biological Survey Collection, from State of Tamau- 
lipas, [Mexico (45 miles from Brownsville, Texas); collected in 1892 by 
Frank B. Armstrong. 
General characters. — Larger than Scalopus a. texanus, color less ochra- 
ceous; skull high and arched, with prelachrymal region much swollen; 
rostrum broad; audital bullae high and well defined; zygomata heavy; 
posterior edge of lachrymal foramen meets zygomatum at nearly right 
angle; mandible heavy; outer groove in third upper ])remolar ])ro- 
nouuced; first lower ])remolar small and inconspicuous. 
Color. —Back between wood brown and drab, becoming ochraceous- 
buff on cheeks; underparts general tone of color much as ou back but 
more mixed with mouse gray. 
Measurements. —Skull of type: ])alatilar length, 13.4; breadth acro.ss 
mastoids, 17.0; interorbital constriction, 7.1; maxillary tooth row, 11.1; 
mandibular molar-premolar row, 11.0. 
Remarks. —The description of this remarkable new mole is based upon 
a single specimen in the Biological Survey Collection, which has remained 
for several years with the skull inside the skin. When the skull was re¬ 
moved it showed many characters warranting its recognition as a distinct 
species. Unfortunately the specimen is imperfect; it lacks comj)lete data, 
the })elage is rather ragged and |)(*rhaps faded; the skull has the ]>osterior 
section of the braincase hack of the jjarietals and hasioccipital broken 
away.
