specimens I obtained in the dredge were dead shells. In this 

 species and E. speciosa the inner lip is smooth within, but in 

 h. ciemmidosa it is internally thickened and lirate and crenate 

 at the margin ; in E. Japonica the aperture is also less circular 

 HI its outline. 



Enida speciosa, A. Adams. 

 E. testa depresso-conica, late umbilicata ; anfractlbus U, planiusculis 

 ad suturas angulatis, liris subconfertis transversis granulosis (inter- 

 sti lis elevate et oblique striatis) instructis, aufractu ultimo ciu- 

 gula valde creuulata ad peripberiam ornato ; apertura obhque 

 quadrata; labio recto in medio late reflexo ; labro prope suturam 

 angulato, mtus lasvi ; suturis canaliculatis ; basi liris concentricis 

 granulosis majoribus cum minoribus altcrnantibus ornata • umbi 

 hco lato, perspectivo, margine crenulato. Colore albido, maculis 

 ruio-tuscis radiatim picto. 



Hab. Off Mino-Sima, Straits of Korea; 63 fathoms. 



This species is more depressed and more widely nmbilicated 

 than E. Japomca, and the whorls are rather concave at the 

 upper part; the granular lira; are wider apart, and the oblique 

 strise of the interstices coarser. 



Enida gemmulosa, A. Adams. 

 ^. testa depresso-conica late umbilicali, suturis profunde canalicu- 

 latis ; anfractlbus rotundatis, seriebus transversis granulorum squa- 

 miforimum confertorum oruatis, quinque in aufractu ultimo, an- 

 fractlbus superne et prope suturas tenuiter plicatis ; apertura 

 rotundato-quadrangulari ; labio in medio excavato et valde reflexo- 

 labro margine crenato iutus incrassato et sulcato, basi convexius- 

 cula seriebus quatuor granorum squamiformium instructa : umbi- 

 lico protundo, margine crenato. 



Hah. OfFMino-Sima; dredged from 63 fathoms. 



This granular species differs very much from the two last 

 described, but partakes of all the characters of the genus. The 

 scale-like granules arranged in transverse rows are very peculiar 

 1 he aperture is nearly circular, and beautifully nacreous and 

 pearly within; otherwise this shell might by some be mistaken 

 lor a species of Echinella. 



Genus Conkadia, A. Adams. 

 Testa turbinata rimate umbilicata, spira elatiuscula; anfractlbus 

 convexis, valde et concentrice carinatis, iuterspatiis sculptis Aner 

 tura circulans ; labio simplici, rotundato ; labro margine fimbriato 

 aut dentate, mtus Isevi ; rima umbilicali costa semilunar! extus 

 marginata. ^^tua 



In many particulars this genus resembles Trichotropis, but 

 the aperture is circular and entire in front. In some respects it
