1915. | T. SOUTHWELL : Indian Parasites of Fish. 253 
p. 296) states that the genus is divisible into three sections. One 
section possess pear-shaped spores each with a single polar capsule. 
In the second section the two polar capsules are of unequal size. 
In the third section are numerous forms characterized by two polar 
capsules of equal size. M. pfeiffert, Thel., gives rise in Europe to 
the deadly ‘‘ barbel disease.’’ MM. cyfrint, Dofl. has been recorded 
from carp. As far as I have been able to ascertain, the only 
papers available in Calcutta which deal with the genus Myxobolus 
are the following :—

(2) Gurley. On the classification of the Myxoporidia, a group 
of Protozoan parasites infesting fishes. Bulletin United States 
Fish Commission, vol. XI for 1891, Washington, 1893, pp. 407-420.

und Perca fluviatilis. Zool. Jahrb., Anal. Abth., vol. IX, text and 
plates, Jena, 1896, pp. 228-272. 
(4) (a) Linton. On certain wart-like excresences occurring on 
_ the short Minnow, Cyprinodon vartegatus, due to Psorosperms. 
(b) Notice of the occurrence of Protozoan parasites 
(Psorosperms) on Cyprinoid fishes in Ohio. Bulletin United States 
Fish Commission, vol. IX for 1889, Washington, 1891, pp. 99-102 
and 359-361. 
Our specimens apparently do not belong to any of the species 
described in the above papers, but they are very closely related to 
the Psorosperms obtained by Linton from Cyprinodon vartegatus. 
Owing to lack of literature I have been unable to determine 
whether our parasites represent a new species or not. Further, 
as our material was scanty, I have not been able to work out all 
the details regarding the shape of the spores. I have therefore 
deerned it advisable to leave our specimens unnamed, at least for 
the present. Myxobolus cyprini has been recorded from Cyprinus 
carpio, and it is quite possible that our parasites may belong to 
M.cyprint. The following details were ascertained. 
Cyst.—lLenticular. Greatest length 1°I mm. 
Spore.—Length 134; breadth 13+. 
Capsules; 2, equal, 4» in length, 4» in breadth, with a very 
short anterior tail-like process. 
Vacuole present. 
As all my specimens were at once stained and mounted in 
balsam, I was unable to conduct re-actions with iodine, and 
sulphuric acid. 
Habitat.—Sub-cutaneous intermuscular tissue of Rasbora dant- 
contus, Day (=Cyprinus daniconius, Ham. Buch.). 
(2) A parasite encysted in the skin of Cirrhina latia. 
(Plate xxvii, fig. 10). 
Three specimens from Mr. Mitchell, Srinagar, Kashmir, Sep- 
tember, 1914. Mr. Mitchell stated that such diseased fish were 
fairly plentiful. Other genera or species affected were not defined.
