Hawkins, T., F. G. S. : A Memoir on the Ichthyosauri and 

 Plesiosauri, with several Lithographic Prints. Folio, 21. 10s. 

 London, 1834. 



This work, announced in VL 267, is now published, and 

 a copy of it, with which we have been favoured, we have sent 

 to a geologist for review, whose remarks we hope to present 

 in our next number. In the mean time, we may notice that 

 the illustrations contained in the work are striking ; that they 

 present, besides pictures of the wonderful creatures which are 

 the subject of the volume, numerous details of their osteology 

 and general structure; and so supply, we presume, in con- 

 junction with the text, the fullest and most perfect account of 

 these wonders of the animal world of former ages, which has 

 yet been produced. The author in his geological deductions 

 seems in entire accordance with the account of the creation 

 by Moses, taking the separate days as distinct geological 

 epochs.

A Zoological Text Book, by G. R. Gray, is announced, in 

 the Entomological Magazine for April. The text book is to 

 consist of " an explanation of all the terms employed by 

 zoologists in the description of beasts, birds, fishes, reptiles, 

 insects, shells, worms, corals, &c. ; " and it is to be " illus- 

 trated by numerous plates, representing the various parts in 

 their natural situation, and in detail." This title bespeaks a 

 work nearly respondent to one for which we have often 

 wished ; although the title of A Dictionary of the Language of 

 Natural History would more precisely express the kind of 

 work of which we have often felt the want.
