ULIVINA ELLIPTICA Mingazzini Type Species 

 [Figure 127] 



1891 Ulimna elliptica Mingazzini 1891:235 



1899 Ulimna elliptica Labbe 1899: 34 



1903 Ulimna elliptica Minchin 1903: 203, 326 



1907 Ulimna elliptica Saint- Joseph 1907: 164, 174 



Sporonts solitary, ellipsoidal, tapering to a sharply rounded posterior 

 end. Nucleus ovoidal, two or three karyosomes. Dense and opaque. 

 No dimensions given by the original author. Ratio LP:TL::1:4 

 to 7; WP:WD:: 1.1:1. 



Saint- Joseph mentions dimensions as 150 by 90/u; 75 by 33/i. He illus- 

 trates (his fig. 106) a trophozoite with a simple, small, papillate epimerite. 



Taken at Naples and off the coast of France. 



Intestine of Audouinia filigera (delle Chiaje); A. tentaculata Mont., 

 Petaloproctus terricola Qfg., Nicolea venustula Mont., and Polymnia nebu- 

 losa Mont. 



ULIVINA RHYNCHOBOLI (Crawley) Kamm 



1897 Unnamed Porter 1897a: 8 



1903 Doliocystis r hyncoboli . Crawley 1903:56 



1913 Doliocystis rhyncoboli Ellis 1913: 287 



1922 Ulimna rhynchoboli Kamm 1922 (this paper) 



Sporonts attain 700ju in length. A distinct septum, with protoplasm 

 in protomerite the more dense. Epimerite a small pointed papilla with a 

 long slender filament at the end. Nucleus small, spherical. 



Intestine of Rhynchobolus americanus Verrill. 



While the epimerite is described for this and for the preceding species, 

 I am not ready to state that it is the type for the genus. 



Porter notes a peculiar attachment of the parasite while free in a watch- 

 glass to the glass, being attached by the anterior end of the protomerite 

 with such force that the animal cannot be withdrawn without destroying 

 it. 



Genus of Uncertain Position 

 METAMERA Duke 1910:261 



Sporonts solitary, epimerite subconical, apex eccentric with corona of 

 numerous branched digitiform appendages. Cyst dehiscence by simple 

 rupture. Spores biconical.
