BIBLIOGRAPHICAL NOTICE. 



A Synonymic Catalogue of Recent Marine Bryozoa. 

 By [Miss] E. C. Jelly. 

 Students of the systematic arrangement of the Polyzoa will welcome 

 the publication of this exceediuL^ly useful book. The author remarks 

 in the preface that iu the compilation two chief ideas have been 

 kept in view — firstly, to collect as far as possible all tlie names of 

 recent Polyzoa that have been published, and, secondly, " to reduce 

 the synonymy to something like fact." Even a cursory examina- 

 tion of the contents of the Catalogue will give evidence of the, if 

 possible, too conscientious care with which the first part of the pro- 

 gramme has been carried out. For instance, no less than eighty- 

 seven bibliographical references are given to Scrupocellaria scraposa 

 and one hundred and forty to Memhranipora pilosa and its varieties. 

 Many of the papers referred to may be of interest from an anti- 

 quarian point of view ; but, so far as the systematic zoologist is 

 concerned, are worthy only of a place in an index cxpurgatorius. 

 We would not be understood to find fault with the compiler of a 

 catalogue for aiming at completeness, which is one of the chief 

 merits of a work of this description. 



The correct classifying of synonyms requires a practical knowledge 

 of the group. This part of the work has been carried out with 

 considerable judgment. The genera are arranged in alphabetical 

 order, as also are the species included under each genus. The 

 specific names are printed in the same t5-pe as the generic, to dis- 

 tinguish them from the synonyms. A useful, and in this case 

 indispensable, bibliographical index, followed by a general index, is 

 inserted at the end of the book. 



We regret to have to point out a few faults in this valuable 

 work. The synonymy is occasionally incorrect. Farcimia cereus, 

 Pourtales (p. 1G6) is not synonymous with NelUa simple^v. Busk. 

 The insertion of dates of publication in every case where it was 

 possible would have increased the usefulness of the work. 



"With regard to the title of the Catalogue, it is not insular preju- 

 dice but a careful weighing of the evidence which loads us to adopt 

 the name Polyzoa, first applied by Vaughan Thomson, iu prefer- 

 ence to " Bryozoa '' (Ehrenberg), chiefly used by continental 

 zoologists. The arguments for retention of the former name put 

 forward by Mr. Ilincks appear to be conclusive. 



But it would be ungracious to be severely critical concerning the 

 errors, in view of the immense mass of information brought together 

 and arranged with such painstaking labour and judgment. The 

 author assuredly deserves the gratitude of all students of Polyzoa,

The Coccidea of fishes have not yet formed the subject of any 



descriptive treatise, and what we know about them is confined to 



the mere mention of their existence *.
