GASTROPODA. 23 



Defrancia, but upon examination I have come to the con- 

 clusion that it belongs to the same section as the foregoing. 



ALCIRA ELEGANS, H. Adams, Proc. Zool. Soc. 1860, 

 p. 451 ; Tryon, M. of C. vol. v. p. 188, pi. 61, fig. 9. 



HARPA MINOR, Lamarck, var. crassa, Philippi. Cape 

 coast (Phil.). The several varieties of this species are pretty 

 widely distributed in the Indian and Pacific Oceans, but I 

 have not yet met with it from the Cape. 



CASSIS TESTICULTJS, Linne, Reeve, Conch. Icon. sp. 10. 

 A specimen of this well-known West Indian and West 

 African species in Bairstow collection from South Africa. 



CASSIS ACHATINA, Lamarck, Reeve, Conch. Icon. sp. 28. 

 Several varieties of this species are found at Port Eliza- 

 beth, and probably the shell quoted by Krauss as C. Zey- 

 lanica (Lamk.) is one of these. 



DOLIUM LUTEOSTOMA, Kuster, Conch. Cab. pi. 58, fig. 1. 

 This species was quoted by me in the ' Journal of 

 Conchology,' as D. Favanni (Hanley), from which I find it, 

 differs. It is nearly allied to D. variegatum. The South- 

 African specimens differ very little from the Japanese.
