South' African Land-Molhisca. 455 



Shell very minutely perforate, globosely conoid, shiny ; 

 sculpture quite smooth to the eye, highly maguified there is 

 close, very fine, longitudinal striation ; colour ochraceous, 

 Mith an orange ti)ige, a fairly broad band just above the 

 pcripher}^ ; spire rather depressedly conic, apex blunt; 

 suture impressed ; whorls 4, at first regularly increasing, 

 the last more rapidly; aperture broadly lunate, oblique; 

 peristome thin ; columellar margin very feeble, and with a 

 mere indication of reflexion. 



Size : major diameter 14-'5, minor 13"0 ; alt. axis 8*0 mm. 



Animal. — Lo])e at extremity of the foot very long. Right 

 and left shell- lobes very long and narrow, left dorsal lobe in 

 two parts. Visceral sac very dark vmber-broivn from the 

 kidney to the apex. Kidney a rich brown colour. 



Genitalia (pi. xii. fig. 1). — In the species the epiphallus 

 is extremely short, the ccecum is close to the retractor muscle, 

 the fiagellum long, the vas deferens junction at its base. 

 In the figure the spcrmatheca is shown broken after the 

 spermatophores had been taken out of it. There were two — 

 tlie first instance of my finding more than one in this sub- 

 family. One was remarkably perfect (pi. xii. fig. 1 a), the 

 other, the oldest (pi. xii. fig. 1 b), had lost its spines, only 

 their bases remained, the flume is whip-like at the end. The 

 spines are straight and branched from just above the base, 

 all bifid at the several terminations. There are seven on one 

 side basal and fifteen on the other (j^^), the fifteenth is mote 

 distant from its neighbours and represents the bifurcation 

 at the points where the whip-like portion commences {vide 

 pi. xii. fig. 1 b). 



Radula. — The formula is 52 . 3 . 8 . 1 . 8 . 3 . 52, or 

 63 , 1 . G3. The central teeth are, as usual, rather small, 

 the marginals are bicusi)id, points nearly even, on the 

 extreme margin and about seven or eight from the side — 

 among the minute teeth, one here and there is tricuspid. 

 Jaw with central projection.

Locality. Thornybush (3411, Burnup, No. IG, B.M.). 



Animal. — Extreniity of foot with elongate lobe tipped 

 dark, foot divided, right shell-lobe small and narrow, the 

 left quite small. Visceral sac, no markings on ivall of 

 branchial chamber^ a faint band of black above the kidney, and 

 same with faint pale mottliny towards the apex ichich is 

 darker. Pale brown tint throughout.
