half a dozen years or so Sl'^o is indeed, if all these proposed chanp^es 

 be adopted, practically obsolete, while all lists of species of tliat 

 date are hopelessly iti arrears. In these circumstances, it is very 

 satisfactory to find that Dr. Trouessart has been enabled to bring 

 his invaluable ' Catalogue ' up to date by the issue of what he calls 

 a su[)pleraent. As a matter of fact, this is practically a new edition 

 of that work, with the exception that the original references to 

 genera and s{)eeies which retaiu their old titles are not repeated, 

 the student being referred back to the second edition of the 

 ' Catalogue ' itself. In some respects this plan is a decided dis- 

 advantage, since it renders it necessary for every student to have 

 access to the orij:inal work, which in due course will probably be 

 out of print, whereas if references to the place of publication of 

 genera and species had been given in the supplement, the latter 

 would have sufficed for all purposes. Doubtless, however, the large 

 additional expense thus involved would have rendered this plan 

 impracticable. 



The present portion of the re-issue comprises the four orders 

 Primates, Chiroptera, Insectivora, and Pinnipedia (expanded into 

 six by the author) ; and an idea of the number of additions to the 

 species in these groups since the date of the second edition of the 

 ' Catalogue' may be gleaned from the statement that (apart from 

 subspecies) the first of these now comprises 290 against 255. In 

 cases where names are preoccupied or otherwise unavailable, the 

 author has not hesitated to replace them by new ones; but in thus 

 substituting Leplocebus for Semnocebits, we note that he has been 

 anticipated by Mr. Palmer, who suggested Lophoeehus. A name is 

 regarded as preoccupied even when there is some difference in the 

 mode of spelling or in the form of the termination, as in the case of 

 Megaloglossus and M^yalor/lossa ; and in this we think he is right. 

 "Whether, however, naturalists will agree with him in accepting all 

 the emendations and changes that have recently been proposed in 

 mammalian nomenclature (even when they have been suggested in 

 our own columns) remains to be seen. Generic terms are for 

 the most part employed in a wide sense, many of the so-called 

 genera of modern zoology being relegated to subgeneric rank, as in 

 the case of the more typical Bats, where we find Ptenjfjistcs and 

 Pi ftistrellus regarded as groups of Ve$pertiUo. 



When complete, the ' Sujjploraent ' will be invaluable to natura- 

 lists ; and we may wish the author health, strength, and energy 

 to bring his laborious and self-imposed task to a satisfactory 

 conclusiou. — K. L.

 This great catalogue should prove of considerable value to those 

 engaged in research. The present volume (Bacteriology) is divided 

 into two portions — the first an authors* catalogue, in which works 

 and papers are catalogued under the names of the authoix. alpha- 

 betically arranged; the second a subject catalogue, authors' names
