considered that between the highest form of Ape and the very 

 lowest type of man there are too many structural differences to 

 warrant the assumption that there is any real relationship. Dr. 

 Forbes, however, has evidently thought it convenient to introduce 

 the genus Homo, for the purpose of pointing out the respects in 

 which man resembles and yet differs from the man-like Apes, and 

 these points, in the words of Prof. Huxley, are made clear towards 

 the close of his second volume. 



His monograph, which seems to be a very complete one, gives 

 us in a handy form a summary of the most recent views on the 

 classification and geographical distribution of a very important 

 group of mammals, to which the author has added much reliable 

 information concerning their haunts and habits. His own ex- 

 perience as a traveller in countries where Monkeys are found has 

 served him in good stead ; and the very useful coloured maps 

 which he has appended, showing the distribution of both living 

 and fossil forms, are much to be commended. 



The coloured plates, twenty-nine in number, are certainly im- 

 provements upon those originally issued in * Jardine's Naturalists' 

 Library,' having been expressly drawn for these new volumes by 

 Mr. J. G. Keulemans ; but it is to be regretted that more pains 

 have not been taken with the colouring, which has been very 

 carelessly executed. 



It would have been a useful addition if Dr. Forbes had 

 indicated under the head of each species whether any living 

 example is to be seen in the Zoological Society's Gardens.

This is the first part of a new work on British Mollusca 

 which, from the thorough mode of treatment adopted by the 

 author, and the excellent and numerous illustrations given, 

 promises to eclipse all previous text-books on the subject, so far 

 as Great Britain is concerned. 



The introductory matter deals with Classification, Nomen-
