a pair of long*, tooth-like, erect processes at the symphysis of the 

 lower jaw. The internal openings of the nostrils and of the

Cryptotis brevis. PI. IV. fig. B. 



Habit stout ; head rather large ; snout of moderate extent, much 

 longer than the eye, which is rather small; canthus rostralis 

 very obtuse ; the nostril is on the canthus rostralis, in the middle 

 between the eye and end of the snout. The mandibulary processes 

 at the symphysis are not true teeth, but are covered with the 

 mucous membrane, one line long, and slightly bent inwards ; 

 vomerine teeth in two very short oblique groups situated behind 

 the inner nostrils. All the upper parts with numerous small 

 and smooth tubercles. Legs rather short; carpus with two, 

 metatarsus with one small tubercle. Grey, upper and lower 

 parts marbled with brownish ; a brown streak along the canthus 

 rostralis. A whitish cross band between the eyes, bordered by 

 a large brown spot behind. An opening on each side of the 

 tongue for the vocal sac in the male. 



Length of the body 20 lines, of the fore leg 10 lines ; of the 

 hind leg 26 lines, of the fourth toe 9 lines, of the fifth 7 lines. 



A single specimen, from the Clarence River, is in the collec-

 longer than the eye; canthus rostralis obtuse, loreal region 

 slightly concave. Tongue with a very small notch behind ; the 

 inner nostrils small; tympanum distinct, half as large as the

 one-fourth webbed, with the disks of moderate size ; toes broadly
