16 Records of the Indian Museum. [Vor 2S 
(I9gII), as a result of a prolonged investigation of the three 
genera Proteocephalus, Weinland, Ichthyotaenia, Lonnberg, and 
Tetracotylus, Monticelli, stated that ‘‘ the genera Proteocephalus , 
Weinland, and Ichthyotaenta, Lonnberg, ...... are synonyms. 
The name Proteocephaius, being the older should be retained to 
designate the species ’”’, 
Unfortunately I have not the material before me for the 
proper discussion of the question, and I have therefore left the 
species in the nominal genus to which they were referred by their 
authors. 
ADDENDUM. 
Professor Albert Hassall of the United States Department of 
Agriculture (Bureau of Animal Industry) has called my attention 
to certain remarks I made in my report “‘ On some Indian Cestoda, 
Part I” (Rec. Ind. Mus., Vol. TX, Part V, December zon) 
regarding the occurrence of certain cestode parasites in particular 
hosts. 
As a result, I have examined the material again and now 
wish to make the following remarks and corrections. 
Cysticercus cellulosae (pp. 292 and 293 of above paper). 
I remarked upon the fact that it was unusual to find this 
larva in the muscles of Bos taurus. The armature on the head 
led me to the above identification. Professor Hassall, referring 
to this identification remarks that '‘ we have been in the habit of 
determining the armed larval form in the sheep as a larval stage 
of Taenia solium (1.e. as C. cellulosae), but on closer examination 
Dr. Ransom determined that it was an entirely different form, 
and experiment proved this to be a fact. Perhaps ..... you may 
find that these forms represent new species.”’ 
Unfortunately, I have been unable to obtain a copy of Dr. 
Ransom’s paper (Occurrence of Cysticercus of Taenia solium in 
sheep. Amer. Ass. Adv. Sc. N.Y., U.S. (703), June 19, 1908): 
My material consists of three cysts only. The further elucidation 
of the exact nature of these larval forms will depend on my being 
able to obtain more and fresh material. 
I was in error with regard to the identification of Cysticercus 
fasciolarts and C. pisiformis (page 292). The data with reference 
to the above species should read as follows :—
