306 Bibliographical Notices. 



to his aid ; in it he finds the pith and marrow of all that has been 

 published during any year : — the new genera described; references to 

 the descriptions of the new species of any particular genus ; summaries 

 of the more important points in papers which treat of geographical 

 distribution, of classification, of anatomy, physiology, &c. The third 

 volume of the 'Record' forms a systematic guidebook to about 30,000 

 pages of the zoological literature published (with the exception of a 

 comparatively small part) within the year 1866. This number, we 

 further learn from the preface, is divided between the various classes 

 thus :— Mammals 3000, Birds 4500, Reptiles 1000, Fishes 2400, 

 Mollusks and MoUuscoids 2000, Crustaceans 900, Ai-achnids and 

 Myriopods 1000, Insects 11,000 (viz. Coleoptera 5000, Hymeno- 

 ptera 1300, Lepidoptera 2100, Diptera 730, Neuroptera and Ortho- 

 ptera 430, Rhynchota 900), AnneHds 1000, Scolecides 900, Echino- 

 derms 170, Coelenterates 860, Protozoa 900. We believe that in 

 saying we feel we owe a great debt of gratitude to Dr. Giinther and 

 his able coadjutors for the valuable assistance they give us in the 

 yearly summaries of the ' Zoological Record,' we are giving expression 

 not to our individual feehngs, but to those of students in zoology 

 generally. That gratitude is enhanced by the fact that we are 

 aware that the work has as yet been published not only at the cost 

 of much time and labour, but also at the sacrifice of pecuniary loss 

 to Dr. Giinther, his fellow labourers, and that most enterprising pub- 

 lisher, to whom naturahsts owe so much, Mr. Van Voorst. We trust 

 tbat a yearly increasing sale, as the ' Record ' becomes more widely 

 known on the Continent, may by degrees turn that loss into a profit. 

 Meanwhile, at the Meeting of the British Association at Dundee, steps 

 were most justly taken to secure the editor from further loss in the 

 publication of the volume for the ensuing year. We shall rejoice if at 

 future meetings of the Association similar aid is volunteered on the 

 part of the Committee. Most certainly there is no purpose to which 

 a grant in Section D can be more advantageously applied than in the 

 preparation of a publication of the value of which every scientific 

 zoologist is fully sensible, and the discontinuance of which would 

 prove a great drawback to the " advancement of science." 



Volume III. unquestionably surpasses either of its predecessors 

 in the carefulness and completeness of its execution. The Re- 

 corders remain the same as in the former volume ; but they have 

 learned by experience, and, warming to their work, do it more 

 efiectuaUy. Perfection in the first volumes of such an arduous un- 

 dertaking it would have been most unreasonable to look for ; but 

 they came nearer to perfection than could have been expected. 

 Improvement is, however, obvious in the 'Record' of 1866, especially, 

 where it was most needed, in the reports on the lower classes of ani- 

 mals. In the first volume there was no notice on the Coelenterata 

 and Protozoa ; in the second volume the literature of 1864 and 1865 

 was epitomized, but the analysis was not as satisfactory as could 

 have been wished. In the present volume, however, we find this 

 part of the subject well handled.
