In the Maseiim of the Zoological Society of London there 

 is a specimen, obtained from the United States, which I think 

 is the same species. It is marked in the printed catalogue, 

 No. 145 " Sc. Breweri, Bachman's MSS." It however differs 

 in having the fur more compact and shorter, the color some- 

 what darker, and in fact almost black. The hairs of the tail, 

 instead of being of a brownish ash color, are black, and the 

 hind feet, instead of being covered above with brownish 

 white hairs, as in my specimens, are brownish black.

4. ScALOPS LATiMANus. Bach. Broad palmed Shrew-mole. 



Characters. Broad palmed Shrew-mole, larger than the 

 common Shrew-mole, intermediate in size between Sc. Town- 

 sendi and Sc. Breweri. Hair longer and thinner than in either 

 of the other species, and slightly curled. Palms larger than 

 in any of the known species ; color nearly black. 



In the rich and daily increasing collections contained in the 

 Berlin Museum, one of the most valuable in Europe, especially 

 in the Mexican and South American birds and animals, I 

 observed two specimens of an undescribed species of Scalops, 

 obtained from some part of Mexico, which, through the kind- 

 ness and liberality of Professor Lichtenstein, the director of 

 the Royal Museum, I was permitted to describe. I subse- 

 quently received a similar specimen from Texas, near the 

 northern boundary line, and I have no doubt it exists also in 

 Arkansas. I regret that I had no opportunity of examining 

 the skulls and teeth of the specimens in the Berlin Museum,
