318 SUMMARY OF CURRENT RESEARCHES RELATING TO 



Gregarine of Sandhopper.* — L. Mercier describes Cephaloidophora 

 taltiri sp. n., parasitic in the intestine of Talitrus locusta (T. saUator 

 Mont.) It passes from an intracellular phase in the wall of the gut to 

 a free phase in the lumen. It is nearly allied to Cephaloidophora 

 macidata Leg. et Dub., found in Gammarus mariniis. 



Sarcocystis Spores.f — Howard Crawley has made a study of 

 Sarcocystis rileyi in the muscles of a mallard. The spores are 14-15 /t 

 long and 2-3 /a wide ; one end is broad and rounded, the other narrow 

 and tapering ; the cytoplasm is spongy in the central portion, nearly or 

 quite homogeneous in the narrow end. Within, counting from the 

 broad end, the spore shows a vacuole, a chromatin body, a vacuole, and 

 a chromatin body. In being apparently binucleate they differ from any 

 other sarcosporidian spores hitherto described. 



Rare Parasites in Anthomyid Flies.f — J. S. Dunkerly reports the 

 occurrence of a Microsporidian {Theloliania ovata sp. n.) in HomaJomyia 

 scaJaris, and a form of Prowazekia in Homalomyia canicvlaris. The 

 rarity of these two parasites of flies seems to point to a casual infection.
