South- African Lancl-MoUusca. 131 



Tlie shell of aloicohi, var., under iii>xli powers, is smootli 

 on tlie last whorls, witii the faintest indication of irregular 

 striaj lines running longitudinally; near the protoconch the 

 surface is decussate or })unctate. 



Recently (November 1911) 1 have seen quite a number 

 of shells of this species from the Ponsonby collection, fine 

 specimens and fully grown, whereas those sent me, preserved 

 in spirit, wore quite young shells — the major diameters 

 respectively being 11*5 and 16 mm. As is, I tear, generally 

 the case, the finest shells find their way into the cabinet, the 

 finest animals are thrown away, at one time they were never 

 saved at all. 



From Port Elizabeth has been described as a var. of 

 hiuhonicB another species, ahicola, M. & P. I have compared 

 the type shells of this with huJsonia', Bs., type of Pellatus, 

 origiiuilly described in 190S, and I cannot see any difference 

 to seize on. Fortunately one contained a dried-up animal, 

 and this clears the position up, for after a lengthy soaking 1 

 am able to give the following description : — 



Pellatus aloicolor, ]\I. & P. 



Port Elizabeth. 



Animal. — Visceral sac, ground-colour dark brown, with a 

 very large amount of white, broadly distributed, and ex- 

 tending to the apex with a few white spots : vide description 

 of the Grahamstown species. The right shell-lobe and the 

 extremity of the foot had been unfortunately destroyed, but 

 the left shell-lobe was intact, small, and triangular, somewhat 

 similar to fig. 1 «, PI. IV. ; I therefore infer the right shell- 

 lobe is small, as in fig. 1 a of the same Plate. There is a sharp 

 bend in the shaft of the male organ, and the generative organs 

 correspond to those of that Grahamstown species : a well- 

 developed spermatophore is also present. The two specimens 

 are very much alike and may both be taken as typical of 

 the genus Fehatus. More observations of both in a liviu"- 

 slate would be conclusive and are required. The radula was 

 extracted complete ; it has a great number of teeth in the 

 row, the marginals becoming very minute and evenly bi- 

 cuspid. I counted the row to be i)0 . 3 . 13 . 1 . 13 . 3 . 90, 

 or 106 . 1 . 106. Jaw with no central projection as in 

 pi. viii. fig. 1 c, Ann. & Mag. Nat. Hist. ser. 8, vol. i. 



With regard to the sharp S-like bend in the shatt of the 

 male organ which occurs in F. aloicola, var. (PI. IV. 

 fig. 1 h), culedonensis (PI. V. figs. 1, la, B), and trutteriana 

 (PI. VI. fig. 1 c), this is met with in other species, varying in
