Platiris (Spatlia) natalcnsis Lea. Syn., 1870, p. 89. 



Several shells are before me, which I refer to the above 

 species, among them Lea's natalcnsis.

The concentric sculpture is well developed and over most 

 of the surface very fine radiating stri.ne are seen. The epider- 

 mis is olive-green.

 Spatha wahlbcr'^i (part). SiMrsox, Syn., 1900, p. 898. 



There is a large shell in the National Museum collection 

 without locality that I refer to this variety of zvahlbcrgi. The 

 description and figure of S. hartmanni agree with that of 

 tvahlbergi except in the degree of development of the sculp- 

 ture. The shell above mentioned is 131 millimeters in length, 

 68 in height and 34 in diameter. 



Gemain, (1. c), considers this a valid species. 



A'ar. bonrgnignati Bourguignat. 



Height almost or quite one-half the length, the posterior 

 part of the hinge line slightly elevated, and angled where it 

 joins the obli(iuely truncate dorsal slope; base straight or 

 slightly incurved medially.
