BLARINA GOLDMANI. 



25 



lete and without chestnut tip; molariform teeth more deeply concave 

 posteriorly; with postero-internal lobe larger than antero -internal 

 (reverse of mexicana). 



Measurements (taken in flesh).— Type: Total length, 106 mm.; tail 

 vertebrae, 31 mm.; hind foot, 15 mm. Average measurements of 20 

 specimens from type locality: Total length, 101.5 mm.; tail vertebrae, 

 30 mm.; hind foot, 14 mm. 



■General remarJcs. — This subspecies may be recognized most easily by 

 the obsolescence of the postero-internal cusplet of the unicuspidate 

 teeth. Of the forms described in the present paper, it is the least 

 worthy of recognition by name. At the same time, the constancy of its 

 characters and the geographic remoteness of the high mountains it 

 inhabits from the home of tyjDical mexicana seem to entitle it to stand. 

 Mr. Nelson found it living in grassy meadows and forests on the moun- 

 tains, where it had runways like those of the other species. Twenty- 

 five specimens were secured at altitudes varying from 8,800 to 9,500 

 feet. 



BLARINA MEXICANA GOLDMANI subsp. nov. Goldman's Blarina. 



Type from mountains near Cbilpancingo, Guerrero, Mexico (altitude, 10,000 feet). 

 No. 70244, ^ yg. ad., U. S. Nat. Mus., Department of Agriculture collection. Col- 

 lected December 23, 1894, by E. W. Nelson and E. A. Goldman. Original number, 

 7231. 



General characters. — Similar to B. mexicana in size and general ap- 

 pearance, but head and shoulders more plumbeous (less dusky) and 

 under parts very much x)aler. 



Color. — Upper i^arts sooty plumbeous, darkest on rump ; bridge of 

 nose darker than rest of head; under parts plumbeous, decidedly paler 

 than upper parts. 



Cranial and dental characters. — Skull similar to that of mexicana,hiit 

 brain case flatter, only slightly elevated above plane of rostrum. Uni- 

 cuspidate teeth narrower at base; large upper premolar broader behind 

 antero-internal cusp and more excavated posteriorly. 



Measurements (taken in flesh).— Type: Total length, 100 mm.; tail 

 vertebrje, 28 mm.; hind foot, 13 mm. Average measurements of 5 

 specimens from type locality: Total length, 100 mm.; tail vertebrae, 

 28.5 mm.; hind foot, 13.2 mm. 



General remarl-s. — Blarina goldmani is closely related to B. mexi- 

 cana, differing chiefly in paler under parts, flatter brain case, and slight 

 dental characters. The close resemblance is surprising, in view of the 

 remoteness of the type localities of the two and the great difference in 

 altitude at which they live. The 5 specimens on which the present 

 species is based were collected in damp thickets among fir trees at an 

 elevation of 10,000 feet.
