Mr. A. Adams on new Mollusca from Japan. 409 



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

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

 E. gemmulosa it is internally thickened and lirate and crenate 

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

 in its outline. 



Enida speciosa, A. Adams. 



E. testa depresso-conica, late umbilicata ; anfractibus 4|, planiusculis, 

 ad suturas angulatis, liris subconfertis transversis granulosis (inter- 

 stitiis elevate et oblique striatis) instructis, anfractu ultimo cin- 

 gula valde crenulata ad peripheriam ornato ; apertura oblique 

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

 angulato, intus Isevi ; suturis canaliculatis ; basi liris concentricis 

 granulosis majoribus cum minoribus alternantibus ornata ; umbi- 

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

 rufo-fuscis radiatim picto. 



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



This species is more depressed and more widely umbilicated 

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

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

 striae of the interstices coarser. 



Enida gemmulosa, A. Adams. 



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

 latis ; anfractibus rotundatis, seriebus transversis granulorum squa- 

 imformium confertorum ornatis, quinque in anfractu ultimo, an- 

 fractibus superne et prope suturas tenuiter plicatis ; apertura 

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

 labro margine crenato intus incrassato et sulcato, basi convexius- 

 cula seriebus quatuor granorum squamiformium instructa ; umbi- 

 lico profundo, margine crenato. 



Hab. Off Mino-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. 

 The aperture is nearly circular, and beautifully nacreous and 

 pearly within ; otherwise this shell might by some be mistaken 

 for a species of Echinella. 



Genus CONRADIA, A. Adams. 



Testa turbmata rimate umbilicata, spira elatiuscula; anfractibus 

 convexis, valde et concentrice carinatis, interspatiis sculptis. Aper- 

 tura circularis ; labio simplici, roturidato ; labro margine fimbriato 

 aut dentato, intus Isevi ; rima umbilicali costa semilunari extus 

 marginata. 



In many particulars this genus resembles Trichotropis, but 

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