K. pumila, J. Sowerby, Min. Conch, tab. 637. f • 3 ; S. V. Wood, Mon. 

 Crag Moll. p. 124, tab. xii. f 15, a, b. 



Hob. Korea, 36 fathoms; two valves. 'Porcupine' Exped., 

 1869, off the west of Ireland, 422 fathoms : 1870, between Fal- 

 mouth and Gibraltar, 220-795 fathoms. 



Fossil. Pliocene : Coralline Crag, Sutton. The figures in the 

 ' Crag Mollusca ' do not quite agree with the description, nor 

 M'ith specimens which Mr. Wood kindly sent me ; the figures in 

 ' Mineral Conchology ' are excellent. Also Sciacca, Sicily (Mon- 

 terosato) . 



This ought not to remain in the genus Kellia. I should be 

 inclined to place it in Philippi's genus Scacchia as typified by 

 S. elliptica.
