EAST AFRICAN MAMMALS IN NATIONAL MUSEUM. 41 



Genus PACHYURA S61ys-Longchamps. 



1839. Pachyura Selys-Longchamps, Etudes de Micromamm., p. 32. (P. etrusca.) 

 The tiny equatorial African representatives of the 30-toothed musk 

 shrews appear to be very rare or exceedingly difficult to capture. On 

 the Rainey Expedition a single specimen was collected.

The African musk shrews of this genus have recently been mono- 

 graphed by Mr. Guy Dollman.^ Unfortunately this monograph is 

 based almost entirely on material in the British Museum, and no 

 attempt seems to have been made by the author to gather informa- 

 tion about the type-specimens preserved in the American museums 

 beyond that contained in the original description. A number of 

 species described by American mammalogists, therefore, appear in 

 the wrong groups in Dollman's paper, and while the information 

 made available regarding the British Museum material is of the ut- 

 most importance and of great value to workers in this most difficult 

 group, the paper is apt to be very misleading to one v/ho has a small 

 collection to work up without much material for comparison. It is 

 furthermore very evident that the species groups in Crocidura are not 

 yet carefully worked out and, as recognized, are not in any sense 

 circumscribed sections of the genus. 



The fu-st installment of Dolhnan's paper appeared just as I had 

 finished working over the specimens listed in the present report. 

 Since the completion of his synopsis I have gone over carefully for a 

 second time all of our material and have attempted, so far as I found 

 it possible, to arrange the groups and species in the sequence adopted 

 by him. Through the kindness of the Field Museum of Natural 

 History^ Chicago, I have had before me during this work the six 

 type-specimens of East African species of Crocidura from that insti- 

 tution; and the American Museum of Natural History of New York 

 has lent me the one East African type in its possession. The United
