J\Iu3(uni. The a])ical wliorls are sculptured with fine regular 

 longitudinal striation, which merges into finer striation on 

 the rest of the shell. 



The animal in spirit is very pale in coloration, with the 

 overhanging long lobe on the extremity of the foot tipped 

 black, lioth tlie right and left shell-lobes are long and 

 narrow. Foot long, narrow, and divided. 



The wall of the branchial sac is, as Connolly describes it, 

 beautifully streaked and mottled with bhick and pure milky 

 white, the dark spots larger over the kidney and heart. 

 Towards the apex the sutural line is bordered black, with a 

 few white spots. 



The generative organs (PI. YII. fig. 2) are in every respect 

 like those of Peltatus, with the exception of the sheath of the 

 penis being straight, not S-shape; there is a vestibule ; the 

 accessory gland is short and tliick, the flagellnm the same. 

 The spermatheca on a thick stalk, the sac much enlarged and 

 elongately j^ear-shaped. This sac contained a spermatophore 

 (PI. Vll. figs. '2 a, 2 b) in a most perfect stage of develop- 

 ment. On the flume of this are some twenty-five many- 

 branched spines closely set together on one side only ; although 

 in fig. 2 a they appear alternately on either side, it is a 

 twisting of the flume which gives this appearance. The 

 branches do not terminate in the bifid manner as is usually 

 the case, but splay out and become flat-topped. 



Peltatus coti/ledonis, Bs. 



Locality. Koumetje, south of Cape Colony (.1/. ConnoVy). 



Shell strongly decussate next protoconch when examined 

 under high power. 



Animal with foot dark-colonred below, pale al)Ove, with 

 lohe over mucous gland. A tongue-shaped right shell-lobe, 

 dark tipped and finely pointed, and a small left shell-lobe 

 given off from a broad base ; left dorsal lobe divided into two 

 narrow parts. The anterior part of the visceral sac plain, 

 towards the apex dark, w^hite at apex. 



The radula formula is 50 . 3 . 9 . 1 . 9 . 3 . 50, or 62 . 1 . 62. 

 Form of the teeth as in all this genus — the marginals bi- 

 cuspid, inner cusp slightly the longest, the outermost teeth 

 more evenly bicuspid. Jaw with a central projection. 



Captain Connolly tells me " the live animal is of a pecu- 

 liarly orange-brown colour, almost pure orange, especially 

 the under part." Ponsonby gives me this extract from 

 Connolly : — " I am pretty certain that Zingis afra and pi'nguis 

 do not have horns on their tails, while thermanan and cofyle- 

 dom's do."
