576 Lt. -Colonel II. 11. God win- Austen on 



The jaw (PI. XIV. fig. 1 c) of the specimen examined 

 shows little sign of the central projection, and is only slightly 

 concave on the cutting-edge. 



Kerkophorus melvilli^ sp. n. (PI. VII. figs. 1-1 d \ 

 PI. XIV. fig. 2.) 



Locality. Equeefa, Natal (No. 14, II. C. Burnup). 

 Shtdl globosely conoid, scarcely perforate ; sculpture 

 nearly smooth, very fine, microscopic raised dots, in places 

 showing a longiiudinal arrangement ; colour bright oliva- 

 ceous ochre with a green tinge ; spire subconoid ; suture 

 im})ressed ; whorls 4, the last rapidly increasing; aperture 

 ovately lunate; peristome thin, sinuate; columellar margin 

 very weak, thin, and convex. 



(Size : major diameter 17'5, minor lo'O ; alt. axis 8'0 mm. 



The animals were well preserved, two in number; the 



largest was taken for examination. There is a large right 



sliell-lobe, broad and leaf-hke ; the left shell-lobe also large 



and expanding, similar to those oi jjliccdimus and inimctus. 



The animal has no markings. The foot is divided and it 

 has a conspicuous long-pointed lobe above the large raucous 

 glatid. Tlie ground-colour of the visceral sac is pale greenish 

 grey, much s))eckled finely and evenly with small black and 

 white spots (pepper and salt would best describe it) over the 

 branchial cavity, kidney, and heart. The black spots become 

 more numerous near the kidney, and coalescing form a con- 

 spicuous band ; beyond this and towards the part filling the 

 apex of the shell the white spots increase in size, somewhat 

 quadrate in foim, and then a narrow, foliated, irregular 

 edged l)and. The chaiacter of the coloration is similar to 

 that of Kerkop/iorus inimctus ; in that species the apcx is pale- 

 coloured, with no white markings. The respective shells 

 settle and separate the species : inioictus has a much lower 

 spire and is finely banded. 



In the generative organs the penis is closely coiled, as 

 shown in PI. XIII. figs. 7 & 8. The fiagellum is very long 

 and tapering ; the accessory gland is long and bag-shaped, and 

 the strong retractor muscle is given off close to tiie base of 

 it. The spermatheca is very capacious, elongately pear- 

 shaped at the head of a long duct; the walls of this were not, 

 as is usual in other species I have examined, thick and solid, 

 but were so thin and tran.<parent that particles within itcoulj 

 be seen floating about. In the pear-shaped sac only a small 

 poitionof a spermatophure (PI. VIJ. lig. 1} was found, not
