A pale shell, with numerous radiatmg strise, and smooth con- 

 centric ridges, lamellated at the hinder part. The form resembles 

 that of Tapes decussata.

 Astr. iii. 535. pi. 84. f. 24, 26. 



Y. " testa subtrigona, inflata, crassa, transversira obsolete striata, 

 longitudinaliter plicata ; fusco-lutescente, intus violacea." 



Inside dark purple, outside pale greyish; radiating ribs rather 

 broad, crossed by undulating rather distant laminse.

12. Yenerupis fimbriata (pi. clxv. f. 23), Sov)erbi/,jvM. 

 Y. testa ventricosa, pallide fulva, oblongo-subquadrata, radiatim 



planulatim sulcata, concentrice laminis distantibus tenuibus pos- 

 tice fimbriatis productis cincta. 



Like V. ohlonga, Sowerby, but the concentric laminse are thinner 

 and more produced, while the radiating grooves are more distant, 

 and the interspaces flat.

13. Yenerupis mirabilis (pi. clxv. f. 24), Beshayes, Pro. 

 ZooL Soc. 1853. 



Y. subquadrata oblonga, tumida, minute divaricatim striata; 

 concentrice vix laminata, pallida ; intiis alba. 



I am half inclined to think this species should have been placed 

 with the Tapes. It is remarkable for the zigzag striae, which cover 

 the whole surface with an equal texture.

14. Yenerupis Cordieri (pi. clxiv. f. 2), Beshayes, Rev. 

 Zool. Soc. Cuv. 1839, p. 358. 



"Y. testa ovato-transversa, insequilaterali, inflato-cylindracea, 

 transversim eleganter lamellosa; laraellis postice latis, porrectis, 

 in medio attenuatis, antice evanescentibus ; cardine lato, bideutato ; 

 marginibus integris, acutis." 



This fine solid shell, with thick, broad, erect laminse, is from 

 California. We are only able to figure the variety in Mr. Cuming's 

 collection, mentioned by M. Deshayes in the British Museum 

 Catalogue.
