74, Bibliographical Notices. 
the bibliography down to the present time, and, moreover, they only 
give the titles of books and papers, and, as a general rule, give 
little or no idea of the contents. The thing which every student 
must have felt the want of is a synopsis of zoological publications, 
which should be issued frequently, so as continually to keep pace 
with the progress of science. Attempts have been made in this 
direction. The ‘ Reports on the Progress of Zoology,’ at one time 
published by the Ray Society ; the ‘* Notices of Serial Publications,” 
in the first series of the ‘ Natural History Review,’ and the ‘ Zoolo- 
gical Bibliography ”’ of the second series of the same work, and, last 
but not least, the annual “ Bericht’? in the ‘ Archiv fiir Natur- 
geschichte,’ have all been of greater or less use, but have fallen very 
short of what was required. At length, however, the desideratum is 
supplied, and most heartily do we welcome the first volume of ‘ The 
Record of Zoological Literature.’ 
Dr. Giinther is so well known, and the care and aecuracy which 
characterize all his writings are so fully acknowledged, that the very 
mention of his name as Editor of the ‘ Record’ wil] be a sufficient 
guarantee to our readers that the work will be energetically and ably 
conducted. ‘The object of the ‘Record,’”’ as given in Dr. Giin- 
ther’s own words, “is to give, in an annual volume, reports on, abs- 
tracts of, and an index to, the various zoological publications which 
have appeared in the preceding year; to acquaint zoologists with the 
progress of every branch of their science in all parts of the globe ; 
and to form a repertory which will retain its value for the student 
in future years.” The editor is aided in the work which he has 
undertaken by an able staff of coadjutors, each of whom is well 
versed in that branch of Zoology which is more especially entrusted 
to his care. The several classes are thus apportioned among the 
contributors. 
The Epiror himself reports on the Mammalia, the Reptilia, and 
the Pisces. 
ALFRED Newton, M.A., F.L.S., &c., takes charge of the Aves. 
Epuarp von Martens, M.D., C.M_Z.S., the Mollusca. 
J. Reay Greens, B.A., the Molluscoida, Rotitera, Annelida, and 
Echinodermata. 
C. Spence Bate, F.R.S., the Crustacea. 
W.S. Dauxas, F.L.S., &c., the Arachnida, Myriopoda, and Insecta. 
T. Spencer Cospso pn, F.R.S., the Helminthes. 
The gentleman to whom was iutrusted the Record of the Ccelen- 
terata and Protozoa failed to keep his engagement; and the report, 
therefore, on these classes has been, we find, unfortunately deferred 
to the second volume. 
A few rules have been drawn up for the guidance of the contri- 
butors, in order to secure a near approach to uniformity in the Re- 
cords; and as these will further elucidate the aim and scope of the 
work, we give them here entire. 
“1, To commence each Record with a list of the various publica- 
tions, arranged chronologically, systematically, or alphabetically, 
with such remarks on their object, extent, and nature as cannot well 
be embodied in the special part of the Record. The student should
