predict that when its dentition has been examined it will be found 
to differ in no important respects from the dentition of that genus. 
5. Moxossus onscurvs, Geoff. (M. fumarius, Spix?) 
This Bat is common over the greater part of South America, and 
one differing only in being a little smaller occurs in the West Indian 
Islands. Mr. Gosse mentions it as M. fumarius. Specimens from 
St. Croix precisely resemble the Jamaican ones. 
6. ? 
A small animal about the size of the Water Shrew (Sorex fodiens), 
with external characters and incisor teeth so much like those of the 
Soricide as to have led in the first instance to the belief that it was 
a placental Insectivore, perhaps in some degree resembling the Sole- 
nodon of Cuba. However, the existence of a small and rudimentary 
pouch sufficiently attests the implacental nature of the creature, 
which but for this must certainly, as far as external appearances go, 
be regarded as one of the Soricide. A more ample account of it 
will be given on a future occasion. 
7. ScCIURUS ZSTUANS. 
The specimens contained in the present collection differ from those 
in the former one in having all the under-parts, which in them were 
but of a pale Trust-colour, of a deep bright ferruginous hue. The 
males and females are similar. They are all from Pallatanga; and 
the native name, Mr. Fraser tells us, is “ Ardillo.” 
8. HErsPEROMYS RENGGERI, Waterh. 
Of this species the collection contains a good number of specimens 
which differ in no important respect from those obtained by Mr. 
Bridges in Bolivia. 
9. H. eLeGaAns, Waterh. 
Only two specimens appear, and one of these differs very consider- 
ably from the other in having longer and more pointed ears, and in 
being itself somewhat larger ; but these differences I do not consider 
sufficient to constitute a specific distinction. The crania of these 
examples are similar, excepting a little difference in size, and are both 
remarkable for the great length of the incisive foramina. 
10. H. LATIMANUS, 0. 8. 
The present species, of which the collection contains but a single 
specimen, a male, accords with moderate accuracy with the dimen- 
sions given of the Mus pyrrhorinus of Prince Maximillian, but differs 
so remarkably from this and all other species with which I am ac- 
quainted, or can meet with descriptions of, in several important par- 
ticulars, that I regard it as new, and propose to describe it under the 
above name. 
The face is short, and the muzzle rather tumid ; the muffle very
