353] STUDIES ON GREGARINES— WATSON 143 



Ellis described this species as a Stenophora because of 



" — the papilla at the anterior end, which results from the expansion of the thin 

 epicyte. Such a process has already been described by the writer (1912:661-6) in. 

 another species of this genus, 5". cockerellae Ellis, from Guatemala." 



The shape of the protomerite is very unlike that of the Stenophori- 

 dae, being twice as wide as high, while in this family it is globular or 

 subglobular. The Stenophoridae are confined to the Diplopoda. Al- 

 though no positive factors are present to indicate its position, yet from 

 exclusion of factors, this species would fall under the family Actino- 

 cephalidae. The general shape is not unlike that of Actinocephalus 

 conicus (Dufour) Stein (Figs. 75 and 76). The two most important 

 determinative factors, epimerite and spores, are unknown and so the 

 determination cannot be absolute. 



ASTEROPHORA PHILICA (Leidy) Crawley 



[Figures 78, 113] 



1889 Gregarina philica 

 1903 Asterophora philica 

 1913 Anthorhynchus philicus 



Asterophora: Sporonts solitary, very elongate. Length 300 to 

 2000/i. Maximum width 150/a. Ratio length protomerite : total length 

 : : 1 : 10 to 1 : 15 ; width protomerite : width deutomerite : : 1 : 1.3. 

 Protomerite conical, sharply pointed when deprived of epimerite, longer 

 than wide. Constriction at septum not deep. Deutomerite widest at 

 shoulder, tapering from thence to an attenuated, sharply pointed poste- 

 rior extremity. Epimerite a circular, flattened cushion with a fluted 

 periphery, situated upon a short neck at the apex of the protomerite. 

 Endocyte and nucleus not described. 



Cyst and spores not known. 



Taken at Philadelphia, Pa. Host: Nyctohates pennsylvanica de- 

 Geer (N. pennsylvanicus). Habitat: Intestine. 



The above description is taken from Leidy (1889). He remarks 

 that 



" — the epimerite consists of a horizontal circular disc with a round milled border." 



In a review of Leidy 's Mss,, Crawley found three more drawings 

 from the same beetle. Crawley's words concerning his disposition of 

 the same are as follows : 



"Asterophora philica Leidy.

It is impossible to give a description of this species. Figs. 31 and 32 are
