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, &. 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 Molluscoids 2000, Crustaceans 900, Arachnids and 
Myriopods 1000, Insects 11,000 (viz. Coleoptera 5000, Hymeno- 
ptera 1300, Lepidoptera 2100, Diptera 730, Neuroptera and Ortho- 
ptera 430, Rhynchota 900), Annelids 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 feelings, 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 naturalists owe so much, Mr. Van Voorst. We trust 
that 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 
effectually. 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.
