108 SPOROZOA. 



Remarks. — The genus has previously been reported from 

 beetles and fleas only. I doubt if the species has been correctly 

 referred to the genus Steinina, as in that genus the epimerite 

 is a short, mobile, digitiform process changing into a flat 

 crenulate disc. 



Habitat. — In the intestine of the Indian crab, Metaplax 

 dentipes Heller : Bengal, Port Canning. 



4. Family DACTYLOPHORID^ Leger, 1892. 



Epimerite complex. Sporonts soHtary. Gametocysts dehisce 

 with lateral pseudocyst or by simple rupture, Sporocysts 

 elongate, cylindrical or elUpsoidal, Parasites in Chilopoda.

Protomerite formed of two long, narrow, horizontal lobes, 

 fused and upturned spirally at one end. Periphery shows 

 many teeth, and long slender filaments project from it. 

 Cyst dehisces by pseudocyst. Spores long-ovoidal, united 

 in oblique chains. In the intestine of Mjrriopods. 



Remarks. — The name Nina is preoccupied for a moUuscan 

 genus, Nina J. E. Gray, 1850. The second nsbiae, Pterocephalus, 

 is also inadmissible, being preoccupied for an elasmobranch 

 fish, Pterocephalus Swainson, 1838. It may incidentally be 

 remarked that the name Pterocephalus has also been wrongly 

 used for a Nematode (0. Linstow, 1899) and a Trilobite 

 (F. Raw, 1907). I have, therefore, renamed the genus 

 Grebneckiella, after the author of the type-species. 



41. Grebneckiella navillae (Mitra & Chakravarty). 



■^Nina navillse, Mitra & Chakravarty, 1937, p. 1. 



Sporonts soHtary. Gametocysts oval. Sporocysts spherical 

 to oval, with two envelopes ; liberated in chains.
