South- African Land-MoHusca. 467 



perfect speroiatophore buried in a mass of thick mucus, 

 out of which it was ditiieult and to!)k a long time to clear, 

 using a fine brush and needle-point. In doing this it is 

 impossible to avoid breaking off many of tlie delicate spines. 

 Tlie spermatophore is not always thus enclosed in mucus, 

 and may be found perfectly Free and tloatiug in a clear 

 licjuid. The capside of this specimen is moderately long 

 and cylindrical, the Hume a little more than H times as 

 long. :itte:uKite at the vas deferens end, having a shorter 

 terminal end branching oft' below. 



The sprigs, as they may be termed, carrying spines are 

 very numerous on one side of the flume, thirty in number; 

 on the opposite side there are only four, situated close to 

 the ca[)sule '^,). 



The general form and jirop ortion of its ditferent parts 

 differ in detail from those I have found and described in 

 other 'iiJecies of this genus. The sprigs are set very close 

 together on rather elongate substantial stems, and the ^tag's- 

 horn character of those which are perfect, 17 . 18 . 19 [vide 

 fig.), is not exactly what I have seen before, and approaches 

 nearest to K. vilalis. 



The radula is peculiar; the marginals ar- short, slightly 

 curving, unevenly bicuspid, the outer cusp much below the 

 inner, arranged thus — 



80-100 . 3 . 15 . 1 . 15 . 80-100. 



Jaw slightly arched, with a central projection. 



Kerkophorus burnupi, sp. n. (Part T., pi. ii. figs. 2, 2 a, 2h, 

 Huimal ;' PI. XX. hgs. 1-1 b.) 



Locality. Town Hill, Maritzburg (^No. 15, H. C. Ih/ntitp) ; 

 two specimens sent with shells. 



Shell depressedly globose ; colour nearly -white, but with 

 the palest tint of greenish blue ; spire low, apex rounded ; 

 whorls ;3, the last rapidly increasing and ample ; aperture 

 roundly lunate, about as broad as high, oblique ; columellar 

 margin not reflexed, curving, and nearly vertical. 



Size : major diam. lO'O, minor 8'0 ; alt. axis .■3'8 mm. 



Mr. Burnup, in sending this species, says : — *" This species 

 has never been described (at least no deserijjtion of the 

 form has been published, though I believe Melvili and Pon- 

 sonby have it in MS., but are keeping it back). It has at 

 ditlerent times been identified as II. jj/uedimt/s and as leuco- 

 sjjira ; l)ut 1 think it is (piite distinct ficnn these species."
