* These are 1399 in number, and are distributed as follows '—Mammalia, 125 ; 
Ares, 01 ; Reptilia and Batrachia, 16 j Pisces, 38; Tunicata, 5; Mollusca , 144- 
Bracliiopoda, 2; Polyzoa, 1; Crustacea , 37; Arachnida, 69; Myriopoda, 7* 
lnsecta, 765 ; Echinodermata, 43 ; Vermes, 37 ; Ccelenterata, 6 ; Spongice, 12 • 
Protozoa, 31. In 1883, 1884, 1885 (the volumes in which the totals were last stated)’ 
the numbers were respectively 1015, 1033, and 1066. The great increase in the 
present year is apparently in large part due to the very numerous names proposed 
in some divisions for fossils. There is, however, an increase of upwards of 100 in 
the lnsecta, and this is not palaeontological.
