The sculpture is less fine and the dorsal part of the shell more 

 elevated and angular than in A. scahrmscula; at the hinder side 

 the lamiuse suddenly become few and broadly laminated.

52. Artemis subrosea (pi. cxliii. f. 61), Gray, Yates' New 

 Zealand, p. 309. 



Art. testa pallide rosaceo-fulva, latiore quam alta, tenui, con- 

 vexa, concentrice creberrime elevatim striata, striis ad latera lami- 

 natis minutissimis ; area ligamenti subexcavata, striata; lunula 

 ovali, impressa. 



Of a rather oval form, with very fine striae, which are so close 

 at the umboes as to give a glossy appearance to the surface. This 

 species differs from A. Jcqwnica and A. scahriuscula in having the 

 strise as close at the sides as at the middle of the shell.

Remarkable for the corrugated character of the ridges on a 

 distinct portion of the posterior side, and for the row of large 

 laminated scales, into which some of the ridges are expanded at. 

 the edge of the ligaraental area.
