REPORT ON ZOOLOGY, MDCCCXLII : 
the aid of these beautifully drawn and faithful portraits, one can easily 
form a clear idea of the different English races of these animals. 
Verzeichniss der in dem Museum der Senckenberg. naturf. 
Gesellschaft aufgestellten Sammlungen, 1st Abtheil : Saiig- 
thiere und deren Skelete. Frankf. 1842. 
This Catalogue, prepared by Dr. Euppell, is a voucher for those who 
cannot personally visit the Senckenberg Museum, that this magnificent 
institution can show one of the most remarkable collections of the Mam- 
malia, both in stuffed specimens, as well as in skeletons and skulls. It is 
already known, that a great portion of this collection has been brought 
together by RiippeU’s unwearying activity. 
It is much to be desired, that an index to the contents of all such 
great collections should be from time to time published. 
We are also indebted to the same author for two excellent Treatises 
on Therology, in the third volume of the Museum Senkenbergianum. 
The first is on Mammalia, of the order Rodentia, observed in the north- 
east of Africa ; and the second is a description of several New Mam- 
malia, to be found in the Zoological Collection of the Natural History 
Society of Senckenberg. These two treatises will be more particularly 
discussed in the division of this Report appropriated to species. 
Descriptions of some New Genera, and fifty unrecorded 
Species of Mammalia. By J. E. Gray. (Ann. and Mag. of 
Nat. Hist. X. p. 255). 
A fair number of new species are here made known to us, but unfor- 
tunately in a very incomplete manner, frequently without mention of size, 
seldom with a comparison of them with known species, so that, in many 
cases, without specimens, it is impossible to make them out. Meanwhile, 
we shall only mention the names of Gray’s new genera, which are as fol- 
lows : — Sturnira, Noctulinia, Trilatitus, Kerivoula, Myotis, Murina, Har- 
piocephalus, Centurio, Osmetectis, Nesokia, Vandeleuria. Although 
these names are not so uncouth as those of Lesson, yet the most of them 
are sufficiently barbarous to debar their entrance into the system. Why 
should the rules of Linnseus, for nomenclature, which are to be found in 
his Philosophia Botanica, and repeated by lUiger in his Prodromus, not 
be generally recognised in England and France? This should be the 
express condition under which any new names ought to be received. 
Luckily, in the present case, most of the genera are of one character, so 
that they may be cashiered at the same time with their uncouth names. 
Of the more general works on the internal structure of the 
Mammalia, the following may be mentioned : —
