tail nearly as scantily haired as the average B. talpoides. The 
latter species, however, never shows the extreme hairiness of tail 
often found in B. brevicauda. 
The skulls of B. brevicauda and B. talpoides differ in general 
size and in the proportionate development of the rostrum. Five 
skulls of B. brevicauda average 23.64 mm., in total length 
(exclusive of incisors), while the average of twenty skulls of B. 
talpoides is but 22.60 mm. In B. brevicauda the ratio of greatest 
anto-orbital width to occipito-rostral length is 38.16, against 
33.27 in B. talpoides. Although the greater breadth of the 
rostrum makes the brain case appear proportionally narrower in 
B. brevicauda^ the development of this part of the skull in the two 
species is in reality nearly the same, since the ratio of greatest 
post-orbital width to occipito-rostral length is 55.83 in B. 
brevicauda, 54.77 in B. talpoides. 
The teeth of Blarina brevicauda are, like the skull, more 
heavily built than in B. talpoides, but I can find no differences 
in relative size or form. 
Concerning the geographic distribution of these two shrews 
nothing definite can be said. Blarina brevicauda ranges from 
western Iowa and southeastern Nebraska north to central and 
eastern Minnesota, while B. taliyoides occurs from near th.e east- 
ern side of Lake Huron to the Atlantic coast. Whether the 
two forms will be found to intergrade somewhere in the region 
of the Great Lakes is entirely problematical. For the present 
they must stand as distinct species.

A fine specimen of the hairy-tailed mole is in the collection 
of the Franconia natural history society. 
8. CoNDYLURA CRiSTATA (Linn6). 
An adult male taken in the Alpine Garden (5,400 feet), Mt. 
Washington, July 9, 1893, is slightly smaller than the average 
of twenty specimens from Peterboro, N". Y. Although small in 
size the animal is fully adult, with claws much worn. The 
specimen was taken in a "cyclone" traj) set in a cavity beneath 
the turf close to a small stream. No indication of moles' work 
could be found here or elsewhere on Mount Washington. 
Specimens of this species, including a family of half grown 
young, are in the collection of the Franconia natural history 
society.
