be fully informed what he may expect to find in the work or memoir,

necessary for the object in view. 
** 2. To arrange the contents of all the publications systematically 
in the second, special part of the Record. This part will con- 
tain almost all the abstracts of memoirs and papers, new systematic 
arrangements, and discoveries. Papers difficult of access to the 
generality of zoologists to be given more in detail than others. 
“© 3. Of new genera short diagnoses are to be given, if, in the opi- 
nion of the Recorder, such genera are likely to take a place in the 
system, whilst the names only of subgeneric divisions’’—those abor- 
tions of science !—‘‘are mentioned. All species described as new, 
with their habitats, and emended descriptions of known ones, are to 
be enumerated, with exact references to the several works and 
mention of accompanying illustrations. Diagnoses of new species 
to be given only when they are described in a journal or work diffi- 
cult of access. 
“4. The titles of anatomical papers to be given; but only those 
to be more specially treated which have a direct bearing on the classi- 
fication, specific definition, or the life-history of an animal. 
*©5. The boundary-line between popular and scientific literature 
having become of late rather indefinite, such popular publications to 
be mentioned as deserve attention by their tendency to promote 
scientific knowledge, directly or indirectly.” 
The result of the joint labours of the contributors is a thick octavo 
volume of more than 600 pages, containing an immense amount of 
well-digested matter. It astonishes us to find the progress which is 
now being made in the investigation and description of the entire ani- 
mal kingdom throughout the world. We have skimmed through the 
pages of this volume for the purpose of ascertaining the number of 
genera which have been described in the year 1864, and we find 
that they amount to 948. This immense addition to the generic 
nomenclature is thus distributed among the primary divisions of
