* The number of new genera and subgenera recorded in the present volume 
is 1015, as against 1438 of vol. xviii. Without the Protozoa, which in the latter 
comprised 483 from a single describer, the number is greater by 70 ip the pres nt 
one. These 1015 are divided as follows ‘.—Mammalia, 29 ; K Aves, 19 ; Reptilia and 
'llatrachia, 34 ; Pisces, 23 ; ' Mollusca and 'Molluscoida, 67 ; Crustacea, 46 ; 
''Arachnida, 64 ; s Myriopoda, 5; Insecta, 598 ; Vermes, 32; y E chino dermata, 30; 
Coelenterata, 27 ;'Spongiida, 17; and ' Protozoa, 24. The unavoidable delay re- 
ferred to in the preface has necessitated the publication of this long list of new 
names with scarcely any examination as regards prior occupation. — E. C. It.
