found in the genera Stephanophora and Dactylophorus. Its method of 
extrusion is suggestive of the pseudopodia of Rhizopods. 
2) Stenophora elongata sp. nov. (fig. 4). 
Type locality, Quirigua, Guatemala. February 1912. 
Host, Orthomorpha coarctata (Saussure), a Diplopod. Det. Prof. 
R. V. Chamberlin. 
Average specimens, 200 u to 350 u; smallest observed, 21 u; 
largest, 390 u. 
Habitat, intestine. 
Length of the protomerite from 18 Fig. 4. 
to 26 in the total length of the gregarine 
in specimens over 100 «; width of the 
protomerite 1 to 1,6 in the maximum 
width of the deutomerite. 
Protomerite always more or less 
pentagonal, with the two exposed lateral 
angles somewhat rounded and the an- 
terior median angle rather truncate; al- 
ways wider than long andincreasing very 
little in diameter after the gregarine has

unexpanded papilla. This gregarine had partly telescoped the protomerite into the 
deutomerite. Drawn from a cleared preparation.

reached the length of 100 u; capable of being telescoped to some extent 
by the deutomerite; region of maximum width in the posterior half; line 
of demarcation between the protomerite and deutomerite very distinct. 
Deutomerite in specimens over 100 «, much elongate and very mo- 
bile; region of maximum width in the anterior third; tapering very 
gradually from the region of maximum width to a region about the 
length of the protomerite from the posterior end of the deutomerite, 
beyond this rather rounded with the extreme end somewhat square; in 
specimens under 100 u, varying from slightly elongate through oval to 
almost spherical in very small specimens, much less mobile than the 
larger specimens, extreme posterior end usually somewhat square.
