large and prominent deeply stained granules. The flagelluni, 

 however, seems to be distinctly shorter and the undulating 

 membrane less prominent, while in some the anterior 

 extremity narrows rapidly. Laveran and Mesnil in their 

 species do not seem to have met with the very broad form 

 that we have found. 



Of the trypanosomes of other freshwater fish, T. dani- 

 leivski, Lav. and Mesnil, of the carp (Cuprinus carpio) 

 contains chromatic granules. Its undulating membrane is 

 broad, however, and the flagellum long. T. remaki, Lav. 

 and Mesnil. of the pike has no granules. 



We propose the name T. bancrofti for the species under 

 review, in honour of Dr. T. L. Bancroft. 

 "Milky Barracoota," a disease of the Body Tissues due 

 to a Myxosporidian Parasite Chloroniyxum sp. 



The Barracoota (Thyrsites atun, Euph.) in Australian 

 waters is subject to a peculiar disease, elmracterised by a 

 softening and milkiness of the muscular tissue of the body. 

 This fish appears off the West Australian coast in July and 

 August, and, amongst those caught and exposed for sale 

 in the shops, the " milky " ones can be easily distinguished 

 by their more diflluent appearance and softened feel. The 

 disease is also met with in the Eastern States (New South 

 Wales, Victoria, and Tasmania). On incising an infected 

 fish, the muscular tissue is found to be soft and diffluent 

 and almost of the consistency of thick condensed milk. 

 When portions are seized by forceps and held up, thick 

 drops fall from the instrument, still more accentuating 

 this resemblance. The tissue is whitish or slightly blood- 

 tinted and pulls of! the bones leaving them bare. An 

 examination of stained films from the softened muscular 

 tissue showed the presence of peculiar bodies arranged 

 somewhat in the form of a Maltese cross. Specimens were 

 forwarded to Prof. E. A. Minchin, f.r.s., in whose hands
