230 MR. A. ADAMS ON NEW SPECIES OF LIMOPSIS. [Nov. llj 



4. LiMOPSis CRENATA, A. Aclams. 



L. te,sta oblique ovata, longiore qumn lata, convexa, ohlonga, 

 latere antico rotundato, postico declivi, longitudinaliter radia- 

 tim suistriata, concentiice sulcata, liris concentricis suhdistan- 

 tibus crenatis, ejpidermide dense pilosa, pilis infimbriis concen- 

 tricis dispositis, obtecta, intus alba strigosa, margine ventrali 

 intus crenulato. 

 Hah. Uraga, 21 fathoms; Satanomosaki, 55 fathoms. 

 Most hke L. obliqua in form, but less prolonged from the beaks 

 to the ventral margin ; it is also more gibbous, and the surface of 

 the valves is furnished witAi prominent concentric crenate liree. 



5. LiMOPSis FORSKALii, A. Adams. 



L. testn subtrigonali, solida, orbiculata, suhcequilaterali, tumida, 

 latere postico declivi, riifescente, costellis radiantibus striisque 

 concoitricis elevatis eancellata, costellis minoribus et majori- 

 hus alternantibus, intus pallide rvfa, linea cardinis castaneo 

 tincta, margine ventrali intus Icevi. 

 Ilab. 0-Sima ; Takano-Sima ; on the sands, dead. 

 This is a strong, subtrigonal, cancellated species, most nearly re- 

 sembling L. japonica ; but it is more triangular in outline, the 

 sculpture is much coarser, and the hinge-margin is narrower and 

 more arcuated. 



6. LiMOPSis PHiLippii, A. Adams. 



L. testa vice orbictilaii, subobliqua, gibba, subcequilaterali, pallide 

 fusca, costellis radiantibus cequalibus confer tis lirisque crenu- 

 latis concentricis reticulata, latere postico rotundato, epidermide 

 fusco-pilosa partim obtecta. 



Hah. ? 



This is a gibbous, somewhat oblique species, neatly reticulated 

 with radiating riblets and elevated concentric lines. It is more gib- 

 bous than any of the other species, and the surface of the valves is 

 partly covered with a pale brown epidermis. 



7. LiMOPSis ABYSSicoLA, A. Adams. 



Ii. testa valde obliqua, incequilaterali, gibba, lineis elevatis radi- 

 antibus et Hindis concentricis cremdatis decussata, latere antico 

 brevi, rotundato, postico longiore declivi non dilatato, epider- 

 mide fusca pilosa, pilis infimbriis dispositis, obtecta. 

 Hab. Cape of Good Hope, 136 fathoms. 



This is the species actually dredged from 136 fathoms, off the 

 Cape, during the voyage of H. M. S. ' Samarang.' The shell figured 

 as Pectunculus belcheri (Moll. Voy. Sam. pi. 22. f. 5), a much 

 larger and more compressed species, was, I believe, obtained from the 

 Korean Islands, and most nearly resembles L. cumingi, which, how- 

 ever, has not the ventral margin internally crenate. 



8. LiMOPSis MACGiELiVRAYi, A. Adams. 



L. testa oblique ovata, incequilaterali, gibbosida, albida, costellis
