be seen through the transparent ventral wall of the living hosts. They 

 remain in the same place and are attached by crenulations on the margin 

 of the anterior end of the protomerite. These are pushed out like 

 pseudopodia to fit the particular inequalities of the host'> alimentary 

 canal. The surface of the ectosarcof a cephalont is thickly covered with 

 papillae and finger-like processes. 



Cutaneous Leishmaniosis.* — W. L. Yakimoff and N. F. Schockov 

 have studied cases of cutaneous leishmaniosis ("bouton d'Orient ") in 

 Russian Turkestan, and find that there are two varieties of the parasite 

 (Leishmania tropica), differing in size, shape, and plasmic characters. 



Sporozoa of Canadian Fishes. f — J. W. Mavor makes a contribution 

 to our scanty knowledge of Myxosporidia in Canadian fishes. His 

 material was obtained from the St. Andrew's region, New Brunswick. 

 He describes Ger atomy xa acadiensis sp. n. from the gall-bladder of hake, 

 eel-pout and winter-flounder. In the gall-bladder of the hake (Urophycis 

 chuss) it is usually found attached to an undetermined parasite, probably 

 a species of Myxidium or Ghloromyxum, which is itself attached to the 

 gall-bladder. He deals also with Myxidium lergense Auerbach, 

 Goussia gadi Frebiger, and four other forms.
