- Description of new species of Soricidae in the collection of the Genoa Civic Museum, 
By G. È. DOBSON, M.A, F. RS. 
To the kindness of the Marquis G. Doria Iowe the opportu- 
nity which has been afforded me of examining the specimens 
on which the following descriptions, of three most interesting 
species, hitherto unknown to science, are founded. These species, 
though inhabiting such widely separated countries as Africa and 
Sumatra, belong to the same genus, Crocidura, and even to 
the same section of that genus, characterised by the absence 
of the minute upper fourth unicuspidate tooth, or penultimate 
premolar, the dental formula of the teeth of which, taking into 
consideration the facts adduced in my paper « On the mandi- 
bular dentition of the Shrews (') » and other reasons, which I 
hope soon to bring forward in Part III of my Monograph of 
the Insectivora, may be written thus: 
inc. 3-3, pm. 2-2, m. 3-3 
ee: BWW = 28 teeth. 

Crocidura doriana, n. sp. 
Larger than C. flavescens, Geoffr., but resembling that species 
in general outward form and in the colour of the fur; ears 
moderate, thinly clothed with a few brown, almost invisible, 
hairs; tail and feet thinly covered; the long fine hairs springing 
from its sides are chiefly in the basal half; the feet are compa 
ratively large with moderate claws; the tail, as shown by the 
measurements beneath, appears to vary much in length.
