BLARINA MAGNA. 



29 



Cranial and dental characters, — Skull resembling' that of Blarina 

 brevicauda in size and general appearance, but narrower, with longer 

 rostrum and more arched brain case. The brain case in profile is 

 strongly convex, and the highest point is near junction of posterior and 

 middle thirds. Unicuspidate teeth narrow, with inner cusplet very 

 small. Molariform teeth not at all excavated posteriorly, and without 

 interspaces. Large upper premolar short and broad, with antero- 

 internal angle broadly rounded off. 



Measurements (taken in flesh). — Type: Total length, 134 mm. 5 tail 

 vertebrge, 42 mm.; hind foot, 17 mm. 



General remarks. — Blarina magna^ owing to its very large size, does 

 not require comparison with any known species. The tail is very long 

 for a Blarina (45 percent of the length of head and body). A speci- 

 men from Mount Zempoaltepec lacks the chestnut- brown wash on the 

 throat. Mr. Kelson states that the runways of this large Blariyia are 

 conspicuous m the dense, damp oak forest of the mountains. Only 

 two specimens were obtained. 



Average measurements of the s^yecies of Blarina, 

 [All measurements are in millimeters and from fresh specimens.]
