474 Bibliographical Notices. 
British species are described. This tribe, however, includes the 
greater number of the species. The descriptions are very carefully 
drawn up, and include notices of the larve and natural history where 
these are known, while the determination of the species is facili- 
tated by the insertion under each genus of a tabular synopsis of the 
species contained in it. The synonymy of the genera and species 
is also given with sufficient fulness; a considerable number of the 
species and of their larve are figured, often with details, upon some 
of the plates (twenty-one in number) with which the volume is 
illustrated, the remaining plates being devoted to the illustration of 
the general terminology of the group and to the representation in 
outline of the characters of the saw-like ovipositors, upon which, 
especially in some genera, Mr. Cameron lays considerable stress for 
specific determination. A bibliographical list, giving explanations 
of the abbreviations used, and a full index of both names and syno- 
nyms, complete the volume, which is in every respect a most valu- 
able contribution to our entomological literature. 
We cannot conclude this notice without saying a few words of 
the admirable society under whose auspices this present book has 
been produced. The Ray Society has for many years merited the 
hearty thanks of all British naturalists on account of the important 
series of works which it has brought out—works which it would be 
utterly impossible for any publisher to produce in the same style, 
especially as regards illustrations, except under a certainty of heavy 
pecuniary loss. We have already on several occasions called atten- 
tion to some of these works, which we have been glad to see of late 
dealing more and more with various departments of British ento- 
mology ; and we think that it behoves the entomologists of this 
country to lend the society a helping hand, of which, we are sorry to 
say, it stands much in need. A volume like that under considera- 
tion is not dear at a guinea, even if the subscribers get no more for 
the year; but with increased funds the productiveness of the Society 
will increase, and we may hope to see it once more rival its own 
glories of five-and-thirty years ago.

Tuis is the first zllustrated catalogue and guide-book issued for the 
use of visitors to the national collection. The Trustees of the 
British Museum show their willingness to meet the requirements of 
progressive knowledge, or at least the awakened intellectual inquisi- 
tiveness of the People. They not only set before them the bones 
and shells of bygone creatures, which are the enduring memorials of 
the Past, but give them descriptive words and artistic sketches of 
the extinct animals and their relics, so that the separate fragments
