Ancilla ANGUSTATA, Sovverby. Thes. Conch. Vol. i, p. 

 399, plate 77, figs. 169, 170. Cape Point Lighthouse bearing 

 N.W. by W. f W. ; distant 2^ miles ; depth, 42 fathoms. 



Tritonidea NATALENSIS, Smith. Journal of Conchology, 

 Vol. X., p. iii., pi. I, fig. 23. Tritonidea subruhiginosa, Sow. 

 (non Smith), Joum. of Conch, Vol. VII., p. 368. 



Mr. Smith considers the shell I took for his T. subruhiginosa 

 to be a different species. I adopt this view with some reserve, 

 as some specimens recently received from Japan are distin- 

 guished by very slight differences from the S. African form. 



Oniscia MacAndrewi, Sowerby. Proc. Zool. Soc, i! 

 page 567, Plate XX VII., figs, i, 2. 



Specimens of this rare and beautiful species taken off Natal 

 Coast :0'Xeil Pk.: bearing N.W. \ W. ; distant g\ miles ; depth, 

 90 fathoms ; Port Shepstone bearing N.W. by W. ; distant 1 1 

 miles ; depth, 250 fathoms; and Cape St. Blaize bearing N. 85° 

 W. ; distant ^\ miles ; depth, 27 fathoms. The original speci- 

 mens came from Japan. 



Natica Sagraiana, Orbigny. Var. 



A light coloured variety, taken at Saldanha Bay, Vondeling 

 Island bearing N. \ W. ; distant 3^- miles ; depth, 28 fathoms. 

 The species is evidently very widely distributed. Tryon quotes 

 West Indies, Madeira, West Africa, and Mediterranean as its 

 habitats. 



Vanikoro CANCELLATA, Lamarck. 



A single specimen. Rame Head (Natal) bearing W. by N. \ 

 N. ; distant 3 miles ; depth, 43 fathoms. 



Pleurotoma (Clavatula) gravis, Hinds. Moll. Voy. 

 Sulphur, page 16, pi. V., fig. 6. 



Cape Infanta bearing N .by E. ^ E. ; distant 1 8 miles ; depth, 

 47 fathoms ; Pinnacle Pt. (West of Cape St. Blaize) bear- 

 ing E. by S. ; distant 3 miles; depth, 17 fathoms, etc. 



Tryon (Man. of Conch., Vol. VI., p. 229) amalgamates this and 

 several other totally distinct forms under the head of Clavatula 

 muricata. He does not even call them varieties, but simply 

 synonyms ! This is quite too fanciful a melange ; and it is diffi- 

 cult to conceive by what process or aberration of vision it has 

 been reached. The forms are so manifestly distinct that it is 

 quite unnecessary to go into detail. There are scarcely any 

 two species of the same genus more utterly distinct than C. 

 gravis, and C. muricata, as shown by Tryon's own figures.
