XVIII. PROTOZOA. 
this disease, and the life-history of the parasite has been the subject of 
much investigation. Daniells has worked on the transference of Haemato- 
zoa by means of mosquitos to birds and all the endoglobular blood parasites 
come in for a great share of attention. 
On Sporozoa in general we have papers of importance and interest. 
Leger & Laveran have both added to our knowledge of these forms to a 
considerable extent, as in former years. Laveran & Mesnil describe a 
curious toxin—Sarcocystin—formed by Sarcosporidia. 
Especial mention must be made of Labbe’s Sporozoa in “Das Tierreich,” 
a work that cannot fail to be of the greatest use to specialists on this 
class. Mesnil on the “ Classification of Sporozoa ” is a paper of value 
whilst Caullery & Mesnil’s papers, and especially that on the Aplo- 
sporidia , a new order with Aplosporidium , n. g., as its type, cannot fail to 
command attention. Labbe on the affinities of Siedleckia may, suitably, 
be referred to here. 
There are many papers of interest dealing with other classes of 
Protozoa but all cannot be mentioned here. As already stated, the 
Foraminifera do not comprise so many papers this year. Millett 
completes his account of the living Foraminifera of the Malay Archi¬ 
pelago, and Eimer & Fickert’s lengthy memoir on the forms, relationships, 
classification, and various other matters connected with the class contains 
much that is of interest both from the philosophical and zoological points 
of view. On the Radiolaria few papers have been published but several of 
them are of great length. Rust, Vinassa de Regny & Hinde describe a 
very great number of new species and genera. Indeed the Systematic 
Record of Radiolaria this year is very much longer than the combined 
Records of other classes. Vinassa de Regny describes a great number of 
what he calls “ new forms.” Presumably most of these are new species, 
but the Recorder has not recorded them as such, preferring to give them 
the designation considered suitable by their describer. 
Platt’s paper on the specific gravity of Paramecium and Spirostomum 
is interesting for the author’s method adopted in the determination. 
Wager’s memoir on the relations between the “Eye Spot and Flagellum 
of Euglena ” is a fascinating little work and Jennings’ papers on the 
psychology and reactions to stimuli of Protozoa are sure to excite some 
attention. 
The reproduction—and associated problems—of Protozoa receive atten¬ 
tion from Hoyer in the case of the nucleus of Colpidium , Hertwig on 
Arcella , Scheel on Amoeba & Wallengren on Conjugation of Vorticellidce. 
In conclusion Jenkinson’s review of Hieronymus’ memoir on Chlamy- 
domyxa labyrinthuloides may be mentioned.
