Note. — The following two species of the subgenus Cryptotis were 

 described by Dr. Allen after the present paper was in paged proof. 

 Dr. Allen has kindly sent me the type specimens, and I am glad to be 

 able to add the following descriptions: 



BLARINA OROPHILA Allen. 



Blarina {Soriciscns) oropliila Allen, Bull. Am. Mus. Nat. Hist., New York, VII, p. 340, 

 November 8, 1895. 



Ty][)e locality. — Volcano of Irazu, Costa Eica. 



^' Pelage glossy, very short, soft and velvety. Above dark brown 

 (shading slightly on seal brown), becoming lighter on the sides, and 

 passing gradually into smoke gray on the ventral surface, where the 

 hairs are conspicuously tipped with whitish. Feet grayish brown j tail 

 dusky above, distinctly lighter below, well clothed, and with a minute 

 pencil at tip. Ears rudimentary and not easily detected. 



'•''Measurements. — Head and body, 55 mm. ; tail vertebrse, 21 mm. ; hind 

 foot, 11 mm.; head, 20 mm. 



'^Slttill (too imperfect for comj^lete measurements). — Length of nasals, 

 5 mm.: length of upper tooth row, 8 mm.; distance between outer 

 borders of last molars, 5.5 mm.'^ 



General rema,rl:s. — Blarina oropliila is closely related to B. tropicalis^ 

 from which it differs in the shape of the bases of the first and second 

 unicuspids when viewed from the outer side; thej^ are narrow and have 

 a pinched appearance instead of being broadly rounded off. The ante- 

 rior cusp of the large upper premolar, to which Dr. Allen calls attention, 

 is not longer than in tropicalis and falls far short of the middle cusp of 

 the same tooth.
