2. Neeera nohilis, A. Ad. 



N. testa oblonga, ventricosa, albida, antice rotundata, postice valde 

 rostrata, concentrice plicata ; plicis salientibus, subconfertis, aequi- 

 distantibus, interstitiis concentrice striatis; rostro angulato, re- 

 curvato, ad apicem rotundato ; margine veutrali arcuato, simplici. 



Lat. 1 unc. 7 lin., alt. 1 unc. 



Hab. Mino-Sima ; 63 fathoms : Quelpart ; 52 fathoms. 



A fine species, most nearly resembling N. rostrata, Chemn., or 



N. Chinensis, Gray. The outline of the shell, however, is very 



different, the beak being broad and triangular, and the surface 



of the valves concentrically plicate. 



3. Neeera Hindsiana, A. Ad. 



N. testa oblonga, ventricosa, albida, antice rotundata, postice ros- 

 trata, concentrice lamellata ; lamellis pliciformibus, regularibus, 

 subdistantibus, interstitiis concentrice striatis ; rostro angulato, 

 attenuato, corrugato, recurvato. 



Lat. 10 lin., alt. 5 lin. 



Hab. Gotto ; 48 fathoms. 



The form of this species is very similar to N. elegans, Hds. ; 

 but the lamellae of the valves are regularly concentric, the shell 

 is more elongate at the sides, and the beak is shorter and more 

 recurved. 



4. Neara nasuta, A. Ad. 



N. testa oblonga, obliqua, ventricosa, albida, antice rotundata, postice 

 longirostrata, concentrice striata, striis confertis irregularibus ; 

 rostro elongato, attenuato, deflexo, corrugato ; margiue ventraU 

 valde arcuato. 



Lat. 11 lin., alt. 6 lin. 



Hab. Satanomosaki ; 55 fathoms. 



A ventricose oblique species, with the valves concentrically 

 striated, and the slender elongate beak bent downwards, giving 

 to the shell a very peculiar spoon-like appearance. 



Subgenus Rhinomya, A. Ad. 



Surface of valves lamellar. Hinge with a small triangular 

 cartilage-pit and two lateral teeth in right valve.
