MELVILL : NOTES UPON CYrR/E.'E. 1 23 



C. tabescens (Solander) 

 Var. pell lice US (Mel v.) 

 Var. alveolus (Tapp.-Can.) 

 Var. elaiodes (Melv.) 

 *C rashleigliana (Melv.) 

 *C. latior{},l€i\-.) 

 C. caiirica (L.) 

 I consider it a good species, possessing some of the 

 attributes of the var. microdon (Gray), oifimbriata (Gnil.) some of 

 C. {Naria) irrorata (Gray), others of C. quadriniaadata (Gray), 

 but differing from all in the produced extremities. 



2. Cypreea amphithales (Melv.). 



When, in 1888 (Mem. & Proc. Manchester L. & P. Soc, 

 vol. i., iv. sen, pp. 221, 222), I described this shell as possessing 

 the qualifications of the type of Gray's genus Cypneovula com- 

 bined with the type (Z. algoensis) of the same author's Lupouia, 

 it was from a decorticated specimen that the conclusions were 

 drawn. AVithin the last twelve months, through the kindness 

 of Mr. Sowerby, I have been able to obtain a specimen in the 

 very finest possible condition, which was found by Mr. S. D. 

 Bairstow, of Port Elizabeth, and who, I understand, possesses 

 others in as good condition. This specimen Mr. Sowerby has 

 just illustrated, in his useful work just issued, "The Marine 

 Shells of South Africa,"' pi. v., figs. 94-96, and it has been the 

 means of confirming all the preconceived conclusions drawn 

 from the examination of the first worn and imperfect specimens 

 found. The shell is shining, smooth, excepting for the fine 

 transverse lirre at the base, the back being pale shining fawn, 

 with a darker somewhat maculate fawn-yellow blotcli, extending 

 over nearly the whole area, sides spotted fawn, as in L. algoensis, 

 somewhat wrinkled. In my opinion none of the so-called 

 genera, constituted out of Cypnca, are stable, and even Trivia 

 ought hardly to rank as a sub-genus. 



* To ihcsc species I intend lo refer in a snlisecinent article.
