Souths Ajrican Land-Mullusca. 571 



April 1S78 ; one species radiohifu, v. MaiT., a very fjlobose 

 banded shell, he made the type of his genus Zingis. I gave 

 reasons (/. c. p. 283) why tiiese would be better included in 

 temper's genus Martensia, type inozatubtcensisj which had 

 priority by many years, 



A\ lien we look at the portion of tlie generative organs 

 {L c. |.l. xix. tig. 1 l>) and compare them with those o( Peltatus 

 and allied genera, tliere is a peculiarly close resemblance in 

 0"P^ — particularly observable in the form of the spcrmatheca, 

 an expanded thin-walled sac on the end of a long stalk-like 

 lube; the penis only differing in the absence of a crocum near 

 the retractor muscle ; the grooving on the side of the foot ; 

 the division of the sole ; while the radula is of precisely 

 the same type. I may even go a step further, and on these 

 grounds, to say nothing of contiguity of habitat — in spite of 

 difference in shell-character and that the formation of shell- 

 lobes has not conmienced, — suggest that the genus Martensia 

 can be better placed in the subfamily Peltatinse than in any 

 other. 



Kerkophorns inunctus, M. & P. 

 (PI. III.* figs. 1, la, animal ; PI. XII. tigs. 2-2 e.) 



Locality. Alexandra Junction (No. 3278) f. 



Shell not umbilicate, very globose; sculpture very micro- 

 scopic longitudinal striation, papillate and somewhat irre- 

 gular ; colour pale vinous ochre, with a very narrow indis- 

 tinct peripheral band pale chestnut in colour ; spire low, apex 

 rounded ; suture well defined; whorls 4, increasing regularly 

 and rapidly; aperture widely ovate, oblique; peristome thin, 

 rounded above and sinuate on side ; columellar region vertical, 

 rounded below, weak, slightly reflected near the umbilicus. 



Size : major diameter i7'5, minor 14"5 ; alt. axis 4*75 mm. 



Animal about 40 mm. long in spirit, pale-coloured, with 

 no special markings, the scattered spotting on the visceral sac 

 shows through the shell. Foot divided below; peiipodiaj. 

 margin narrow, with the usual two grooves above, from which 

 well-marked widely separated furrows extend obliquely 

 upwards. 



The hinder part of the foot above is rounded, not keeled ; 

 the lobe above the linear mucous pore is large and rises 

 considerably, ending in a long overhanging sharp point.

 Jan. 1912). 



t The numbers refer to specimens received from those who have 

 assisted me in this work ; they may prove useful for future reference to 

 the spirit-specimens and mounted objects.
