* The total number of new genera recorded, including those of the Arachnida 
for 1878 omitted from vol. xv., is 97(5, as against the 1157 of the latter volume, 
lliese are divided as follows : — Mammalia, 27 ; Aves, 30 ; Reptilia, 28 ; Pisces, 16 ; 
Mollusca and Molluscoida, 74 ; Crustacea, 71 ; Myriopoda. 8 ; Arachnida, 144 ; 
Insecta, 383 ; Vermes, 25 ; Echinodermata, 14 ; Coelenterata, 90 ; Spongiida, 45 ; 
and Protozoa, 21. Apportioning the Arachnida [60 for vol. xv., 8 li for the present 
one], there is an increase of 90 in the new genera of 1879 over those of 1878, 
omitting the Inst eta, in which group the very much less number characterized 
has reduced the total. 
I am requested by some of the Recorders to note that many of the new genera 
included in the excellent Index of ZooL JB. Neap, for 1879 were not actually 
published in that year ; to which remark may be added that, being the first of 
its series, that work does not include some in the present Index omitted from 
former volumes of Zool. Reo. — E. C. R.
