c. SPoROZOA. 
In my preliminary note (12) I recorded the presence of a 
new coccidian in the intestine of the frog, I then gave the 
name Coccidium rane to the organism, But having since 
made a more careful study of the literature, I am reluctantly 
compelled to relinquish the generic name Coccidium in 
favour of the apparently more accurate Himeria. That a 
long-familiar name like Coccidium should have to be com- 
pletely abolished is indeed deplorable. I feel convinced, 
however, that the retention of this name (as Schaudinn and 
Minchin have retained it) is really unjustifiable. Unless our 
system is to be thrown into absolute disorder there can be 
no place for anarchy in zoological nomenclature—whatever 
one’s feelings in the matter may be, The name of this 
coccidian is therefore— 
Eimeria rane Dobell. 
A few words must first be said to justify the specific dis- 
tinction given to this animal, as several coccidian parasites 
have already been recorded in frogs. ‘he history of these is 
briefly as follows : 
Lieberkiihn (87) was the first to describe “‘ psorosperms ”’ 
in frogs. He found these in the kidneys only, not in the 
intestine. ‘he parasite described by him is that now known 
as Isospora lieberkiithni Labbé. In 1870 Kimer (17) found 
in frogs the developmental forms of a coccidian, which he 
considered was probably the same as that which he observed 
in the mouse (Himeria falciformis Himer!). Pachinger (41) 
also found intestinal coccidia 
in the duodenum of Rana 
esculenta. He gave the name Molybdis entzi to them, 
but gave an insufficient description of their structure. It is 
thus impossible to know whether the parasites described by 
Himer and Pachinger correspond with my form or not. 
1 Called by him “ Gregarina” falciformis, however.
