Sporozoa 285 



Fajnily 4. Dactylophoridae. The protomerite is typically metabolic and 

 may serve as a sucker in attachment. In certain species, the "epimerites" 

 are slender temporary structures, tapering to delicate filaments. The 

 cuticle of the microgametocyte persists after gamogony as a "pseudocyst." 

 The spores (Fig. 6. 4, A), ellipsoidal, or cylindrical with rounded ends, 

 are released by rupture of the gametocyst. Members of the family have 

 been reported from the intestine of Chilopoda, 



The following genera are included (66): Acutispora Crawley, Dactylophorus Balbiani 

 (Fig. 6. 8, E), Dendrorhynchus Keilin, Echinomera Labbe (37, 122), Hentschelia Mackin- 

 non and Ray (85; Fig. 6. 8, F, G), Lecythion Mackinnon and Ray (85; Fig. 6. 8, F, 

 G), Metamera Duke (65; Fig. 6. 8, J), Nina Grebnecki (37; Fig. 6. 8, B-D). Rhopalonia 

 Leger, Septicephalus Kamm, Trichorhynchus Schneider. 



Family 5. Didymophyidae. The epimerite is small, resembling the mu- 

 cron of certain acephalines. Early syzygy occurs, in pairs or triplets, and 

 a septum may not be apparent in the satellites. Ellipsoidal spores are 

 released by rupture of the gametocyst. 



The family includes the genus Didymophyes Stein (66). 



Family 6. Gregarinidae. The epimerite is simple, knob-like, or some- 

 what elongated. Syzygy may occur early or late and is commonly multiple 

 in some genera. Spores emerge through sporoducts, often in chains (Fig. 

 6. 4, P-S), or else by rupture of the gametocyst. 



The following genera are included (66): Anisolobiis Vincent, Gamocystis Schneider 

 Gregarina Dufour (2, 126; Fig. 6. 2, H), Hirmocystis Labbe, Hyalospora Schneider' 

 Hyalospanna Chakravarty (14; Fig. 6. 8, E), Leidyana Watson, Protomagalhaesia Pinto, 

 Pyxtnoides Tregouboff (45; Fig. 6. 8, H), Uradiophora Mercier. 



Family 7. Lecudinidae. The epimerite may be knob-like, with or with- 

 out teeth and hooks, or an umbrella-like structure with lobate margin, 

 or cylindrical with a lobate tip. A septum is not evident although the 

 protomerite and deutomerite regions may differ in appearance. The 

 spores are usually ovoid. 



The following genera have been referred to the family, which includes the Polyrhab- 

 dmidae of Kamm (66): Kofoidina Henry, Leucudina Mingazzini (Fig 6 9 J) 

 Polyrhabdina Mingazzini (85; Fig. 6. 9. G), Scyia L^ger, Ulivina Mingazzini, Zy^osoma 

 Labbe (96; Fig. 6. 9, H). "^^ 



Family 8. Menosporidae. The epimerite is cup-shaped, with marginal 

 hooks, and is borne on a stalk. Early syzygy is unknown. Crescent-shaped 

 spores (Fig. 6. 4, O) are released by rupture of the gametocyst. 



A single genus is included: Menospora Lcger (66; Fig.. 6. 9, K).
