EUONYMA. 39 



Aside from Stenogyra, the affinities of Euonyma seem to 

 be with Opeas, Tortaxis and Prosopeas. 



No species referable to Subulina has 'been reported from 

 South Africa. Several species of Opeas have been described. 



1. E. L^EOCOCHLIS (Melvill & Ponsonby). PI. 10, fig. 68. 

 "Shell sinistral, fusiform, the upper whorls somewhat at- 

 tenuate ; whorls thirteen in number, mostly very narrow, 

 broadening distinctly towards the base. The specimens (two) 

 before us being dead, we cannot tell the color, but probably 

 it is pale olivaceous. The whorls are nearly smooth, but are 

 obscurely longitudinally obliquely stria te, the basal whorl 

 slightly angled in front ; aperture oblong, the columellar mar- 

 gin being straightly produced and slightly reflexed" (Melv. 

 & Pons.). 



Length 1 T 3 7 , width -^ inch. 

 Humansdorp, St. Francis Bay. 



Subulina laocochlis M. & P., Ann. and Mag. N. H. (6), 

 xviii, p. 316, pi. 16, f. 3 (Oct., 1896). 



2. E. LYMNE^EFORMIS (Melvill & Ponsonby) . PI. 10, fig. 69. 



Shell conspicuous, olivaceous straw-colored, tapering-fusi- 

 form, cylindric, thin, glossy. Whorls 10 to 11, of which the 

 upper three are dull white, but little shining, the apex itself 

 being obtuse, more or less worn in our specimens; remaining 

 whorls a little impressed at the sutures, slightly swollen, deli- 

 cately and irregularly striate under the lens; last whorl 

 about equal to the preceding three, narrow, prolonged. Aper- 

 ture ovate-lunar; peristome thin, a little contracted above, 

 slightly effuse basally, the columellar margin a little thick- 

 ened, uniplicate. 



Length 39, diam. 8.25 mm. 



Length 34, diam. 7.5 mm. (M. & P.). 



Natal: Karkloop Bush (J. McBean) . 



Obeliscus lymneceformis M. & P., Ann. and Mag. N. H. 

 (7), viii, p. 317, pi. 2, f. 5 (Oct., 1901). 



"A fine species, with no near ally in its fauna. The two 

 examples before us vary slightly inter se, the larger being
