88 CRÜCIDURA (PACHVURA) COQUKRi;i,ll. 



cutting-cusp almost solely constituting the external surface 

 of the tooth , directed backwards , and the posterior point 

 forming only the extremity of the hind edge of the chief 

 cusp. When looked upon from above this tooth is trian- 

 gular with a long process directed forwards. The second 

 molar is provided with a very large internal median prism 

 reaching as low as the chief point of the first molar. 



Loioev jaw. — The two large incisors are raised at their 

 extremity and divergent, leaving between their tips a di- 

 stance equal to their own diameter. 



Habitat : Mayotte , N. W. Coast of Madagascar , where 

 it was collected by Pollen and v. Dam, now deposited in 

 the Leyden Museum and labelled by them »Sore.v coque- 

 relii, n. sp.V" 



I owe the communication of this interesting Shrew to 

 the courtesy of Dr. F. A. Jentink, who has kindly 

 authorised me to describe it. Crocidura (P.) coquerelii is 

 remarkable among all the other Shrews for the unifor- 

 mity of the color of its fur, which is truly and absolu- 

 tely »uidcolor' and »concolor ," certainly an exceptional 

 case among Mammals and especially Soricidae. It is 

 impossible to confound this uew species with any species 

 hitherto described. 



Crocidura (P-) aracilis de Bhiiiiv. of South-Africa differs 

 from it in having the tail stouter at the root and down to 

 the first third of its length ; by the smaller ear-valves and 

 by the reddish-brown chestnut color of the fur being paler 

 on the inferior parts. 



Crocidura (P.) madagascariensis Coquercl differs by its 

 slender body, smaller head, thinner tail and grey-brown- 

 ish color , paler beneath. Finally Crocidura (F. ) etrusca 

 Savi , although closely allied to it differs by its color being 

 grey washed with reddish above, lighter on the sides, becoming 

 whitish on the cheeks, belly, underparts of tail and feet. 



Crocidura (F.) coquerelii, besides, differs from the three 

 preceding species by its small rudimentary premolar (4*^ 

 uj:)per intermediate) , which is separated from the canine 



JVotes from the Leyden M.ii*ieum. A'"ol. 11.
