all indications of the synonymy becomes a very serious defect. 

 We do not mean that in a work like the present anything ap- 

 proaching a full synonymy could be given, but two or three of the 

 synonyms of most importance, especially from a distributional point 

 of view, would have added enormously to the value of the work. 



Apart from this, however, the present work must be regarded as 

 a most valuable contribution to the literature of Ichthyology. The 

 species, as already stated, are all tabulated, and further they are 

 described with quite sufficient detail to enable them to be readily 

 identified ; of a great number excellent woodcut figures are inter- 

 calated in the text, generally one or two under each genus ; and each 

 volume is provided with a full table of contents and a very complete 

 index, which will render the book exceedingly easy to consult. 

 The classification adopted differs somewhat as regards the sequence 

 of the orders from that in general use, and indeed from that of the 

 author's ' Fishes of India,' inasmuch as it commences with the 

 Chondropterygii, which are directly followed by the Physostomi, and 

 these by the Acanthopterygii, the remaining orders coming in the 

 same sequence in both works. No reason is given for this change, 

 which, however, is not of much consequence, as the book is not 

 intended as a guide to Ichthyological classification. 



In the conclusion of the Preface to the second volume the Editor 

 informs us that a volume on Birds may very shortly be expected, and 

 we hope that the concluding part of his own treatise on the Indian 

 Mammalia will not be very long in making its appearance. The com- 

 pletion of this and of the other volumes on Birds and on the Reptiles 

 and Batrachia will furnish students with a most valuable help in 

 the study of the Vertebrata of the Indian region, and we can only 

 repeat the hope that means may be found to enable the Invertebrate 

 fauna to be treated in a somewhat similar manner. Of course the 

 extent of the ground to be covered will always render it impossible 

 to treat the groups of the Tnvertebrata in the style adopted in these 

 volumes, but catalogues with tabulated characters would be of in- 

 estimable value to zoologists, and surely the men might be found 

 to do the necessary work if only the authorities can see their way 

 to carry out such a plan. 



Bergens Museums Aarsberetniny for 1888. 8vo. Bergen, 1889^ 



The Annual Report issued by the Museum at Bergen for the \ r ear 

 1888, besides the usual statements as to the state of progress of the 

 establishment, and an obituary notice of Mr. A. Lorange, the late 

 curator of its Antiquarian department, and a description with figures 

 of some curious vessels, chiefly drinking-eups, formerly belonging to 

 the guilds of Bergen but now deposited in the Museum, contains 

 several articles of considerable interest to naturalists. 



The first of these is a description by Dr. Danielssen of a new 

 species of Uerianlhus, which he names V. borcalis, originally obtained
