114 Analytical Notices of Books. 
To the preceding notice we may add that Mr. Curtis has recently com- 
menced the publication, in separate sheets, of “4A Guide to an Arrange- 
** ment of British Insects; being a Catalogue of all the named species 
‘* hitherto discovered in Great Britain and Ireland.’ Its object is to 
furnish a compact list for the purpose of being carried in the pocket or 
transmitted to correspondents, so as to ascertain at one view the insects 
which are possessed by the student, and those which are desiderata to 
him. It may also be cut up to form labels for cabinets ; and may be 
made use of as a systematic Index to the British Entomology. 
Histoire Naturelle des Mammiferes, avec des Fiqures originales coloriées,

In the present number, nearly the concluding one, of this splendid 
work, the species of Mammalia illustrated are the Patas a Bandeau 
blanc; the Jacchus CEdipus, Geoff.; the Pedetes Capensis, Ill.; the Sci- 
urus ferrugineus, n.s.; the Ecureutl de la Californie; and a Delphi- 
nus designated as No. 4. The text referring to the latter two animals 
does not accompany the figures ; the Jacchus and Pedetes have been long 
well known to naturalists ; and our notice is therefore limited to the Patas 
and the new Squirrel. 
The Patas a bandeau blanc appears hitherto to have been noticed by 
Buffon and Daubenton alone, whose account of it extends no further than 
to point out the single difference indicated by its name as existing between 
it and the Patas a bandeau noir, which is generally known as the Simia 
rubra of Linneus. But the former animal differs from that with the 
black frontlet, not only in this particular but also in several others of at 
least equal importance. The redness of the fur of its upper surface is 
less intense, and has more of an orange tinge; this colour does not 
extend along the outside of the anterior limbs, nor along the tibie, these 
parts being grey like the under surface ; and each thigh is marked by a 
whitish spot just beneath the base of the tail, There are no black whis- 
kers on the lips, and, instead of the black band crossing the forehead, a 
line of black hairs passes obliquely from each temple to unite with the 
corresponding line of the opposite side upon the middle of the head, at
