PHASIS-TRACHYCYSTIS. 147 



A very distinct, large, smooth whorled snail, not easily to be com- 

 pared with any other Cape species. (M. & P.) 



P. FARQUHARI Melvill & Ponsonby. PL 35, fig. 12. 



Shell small, umbilicated, thin, ashy-horn colored ; whorls 4, all 

 over longitudinally pitted-rugose, a little graduate, slightly ventri- 

 cose, the apex papillar. Aperture rounded ; peristome thin, simple. 



Alt. 2, diam. 3 mill. (M. & P.) 



Port Elizabeth, South Africa. 



Helix (Pellet) farquhari M. & P., Ann. Mag. K H. (6), ix, 

 p. 240, t. 13, f. 9. (Sept., 1892.) 



A very minute species, somewhat recalling H. rupestris of 

 Europe. The surface is ashy corneous, irregularly wrinkled with 

 oblique lines longitudinally ; whorls 4, somewhat angled, and simple 

 mouth. (M. & P.) 



P. STROBILODES Melvill & Ponsonby. PI. 43, fig. 62. 



Shell covered-umbilicate, conical, thin, dull white, covered with a 

 silky horn-colored cuticle. Whorls 6, narrow above, rapidly increas- 

 ing, below at the base a little ventricose. Aperture lunar, peristome 

 thin, simple, triangularly reflexed at umbilicus. 



Alt. 5i, diam. 71 mill. (M. & P.) 



Thar field, South Africa. 



Helix (Petto) strobilodes M. & P., Ann. and Mag. N. H. (6), xi, 

 p. 19, t. 3, f. 1. (Jan., 1893.) 



A somewhat conical, closely whorled shell, with simple mouth and 

 narrow umbilicus. Allied to H. loveni Krauss. Two specimens. 

 (M. & P.) 



Unfigured species of Trachycystis. 



HELIX GLANVILLIANA Ancey, Bull. Soc. Mai. Fr. vii, p. 157 

 (1890). Graham's town, eastern district of Cape Colony. Allied 

 to aulacophora, but smaller, etc. 



MACROCYCLIS (Vol. Ill, p. 109.) 



The Australian species, franklandiensis Fbs. (of which R. bed- 

 domei Braz., vol. I, p. 126, is said by Ponsonby to be a synonym), har- 

 riettcd Cox and ramsayi Cox (p. 110), should be removed from 

 Macrocyclis and placed in the genus KHYTIDA (Vol. I, p. 117.)
