JAP VNESE SHELLS ANB FISHES. 103 



CONCHIEEBA. 



Lima elliptica, Jeffreys. 



6 fathoms. Lat. 34° 23' N. ; long. 136° 55' E. 



The specimens (three in number) are much smaller than those 

 from Skye ; but the characters peculiar to this species, and which 

 distinguish it from L. auriculata, are the same, viz. shape, sculp- 

 ture, and obliquity of the central furrow. In the Japanese 

 specimens the upper part of the anterior and posterior margins is 

 sinuous, while in European specimens this part is flexuous. I 

 do not regard this slight difference as a specific character.
