important, but the Eecorder confesses that the chief point about it which 
struck him is the nifinifest desire of the author to tack on his name (in 
the abbreviated form of " Pop,") to every nomenclaturic change or addition 
suggested. Nowhere in his description is n. g., n. sp., or the like to be 
found. Fortunately for the Recorder the Acantharia do not seem to have 
been previously honoured by Popofsky's attention, so he has felt justified 
in replacing " Pop." by the correct designation, so far as he was able to 
ascertain it from the context. 
Many new Hsemogregarines have been observed, chiefly by Billet 
(21-24), Castellani & Willey (63), Nicolle (247-249), Sergent (314), 
and Souli^ (327) ; also, usually associated with new Trypanosomes, by 
Brumpt & Lebailly (50) and Lebailly (179). Lastly, a full account of 
Trypanosomes known up to the time of writing is given by Laveran & 
Mesnil (176). This work, compiled as it is very largely from original 
papers by the authors, affords a good idea of the amount of research 
bestowed by them upon these all-important parasites. 
Besides the works on Ciliates above referred to, mention may be made 
of Faure's paper (105) on new Opercularice. The systematic list of the 
Infusoria is, however, much shorter than last year, while the sole entry 
under Tentaculifera is that of Astrophrya^ a new genus described by 
AVERINTZEV (6).
