326 Rev. L. Jenyns on some German Shrews, 



The length of the young specimens, exclusive of the tail, 

 varies from 2 inches 4 lines to 2 inches 7 lines. 



Duvernoy at one time seems to have entertained a doubt 

 as to this species being distinct from the S. Araneus, but in 

 my opinion there cannot be a question about it. 



II. Amphisorex, Duv. 



(3.) 8. tetragonurus, Herm. — Two specimens in the collec- 

 tion, to one of which I found the name of tetragonurus at- 

 tached, accord so exactly with the square-tailed shrew of this 

 country, described in a former paper (Ann. Nat. Hist., vol. ii. 

 p. 43), as to leave not a doubt in my mind of their identity, 

 or of our English species being the true tetragonurus of the 

 continent. In fact there is not the slightest difference in any 

 one of their characters. The larger of the specimens mea- 

 sures 2 inches 11 lines, with a tail of 1 inch 5\ lines. The 

 smaller measures 2 inches 71 lines, with a tail of 1 inch 6 

 lines. The former is evidently a very old individual, the teeth 

 being much worn, and the tail nearly naked and almost quite 

 square. 



A third specimen seems also referrible to this species, but 

 differs from both those just alluded to in being less bulky for its 

 length, with the head not so broad, and the snout more atte- 

 nuated. The dentition is nearly similar, but the fifth lateral 

 incisor above is rather more obvious from without, and the 

 first four do not diminish in size quite so rapidly. The feet 

 are similar. The tail also is of the same form, as well as thick- 

 ness, but better clothed with hairs, the hairs being longer, 

 especially the pencil at the extremity, and standing more out. 

 The colour of the under parts is somewhat darker, or of a more 

 dirty ash-grey, and blends more gradually at the sides with 

 that of the upper. The length of this specimen is 2 inches 5 

 lines. Its proportions, with the exception above alluded to, 

 are not materially different from those observed in the other 

 individuals. 



(4.) S. labiosus, Nob. — By this name I propose to designate a 

 species which, though veiy nearly allied to the S. tetragonurus^ 

 offers, I think, sufficient peculiarities to be considered distinct. 

 If it had been already noticed by any author, it has not been 

 described in such a manner as to admit of its being identified,
