There is here a siiniliiiity with the species iVoni Simointown 

 iJentified as capsuLt, lis., but they are not the same. The 

 animal compared also side by side with aloicola^ var., is at 

 once seen to be ditl'erent in the distribution of colour and 

 consequently of pattern. 



In the generative organs (PI. V. figs. 1, la) the penis is 

 closely bent on itself in S-shape (B) and held together by 

 muscular tissue ; close above tiiis bend the retractor muscle 

 is given off", and then comes a short straight accessory gland 

 or caecum on the epiphallus, which is not very long, to where 

 the vas deterens joins; here is a fairly long Hagellum. The 

 spermatheca is a large globular sac on the head of a strong 

 and lengthened duct. There is remarkable similarity here 

 with the generative organs of aloicola, var., of Grahamstown, 

 and this extends to the spermatopliore. I was not fortunate 

 enough to find this in a perfect state, but enough pieces were 

 found in the s})ermatheca to show the form of the spines. 

 They were found to be different from those of species hitherto 

 examined from S. Africa. They are beautifully branched, and 

 each branch terminates in a peculiar tiat bitid end (PI. IV. 

 fig. 3). It is interesting to note that in aloicola, var., similar 

 pointed spines occur ; the contents of the sperniatheca in three 

 specimens were examined, and in one two or three such points 

 were discovered, all the rest had been absorbed. The jaw 

 (PI. V. fig. 1 h) has a central projection on a concave edge. 

 The radula (PI. V. fig. 1 c) formula is 58 . 2 . 9 . 1 . 9 . 2 . 58, 

 or 69 . 1 . 69. The admedian are all bicuspid, nearly equally 

 so, becoming more even as they approach the margin. The 

 last three on the edge are very small (PI. V. fig. 1 d) and 

 three- to four-cuspid. 



This is a true Peltatus, its anatomy as regards the genitalia 

 being similar in every respect to the typical species. It 

 differs, however, in the shell-sculpture and in the radula and 

 general colour of the animal.

Captain Connolly writes, under date 12!:h January, 

 1910 : — " With no. 31, ? llelicarion ? n. sp., loc. Simons- 

 town, probably a Peltatus, and Burnup thinks it may be 

 merely a var. of hudsonke. The live animal is palish grey, 

 with a beautifully spotted mantle and long wavy horn on its 

 tail." The shell is not at all like P. hudsonice, of which the 

 type has been preserved both in the B. M. and Cambridge
