118 BULLETIN OF THE 



Lima caribbea (?) D'Orbigny. 



In Yucatan Strait, at a depth, of 640 fathoms, a valve was obtained, which 

 may perhaps belong to this species. 



Lima sp. indet. 



A very young valve, nearly smooth, and equilateral, was obtained from 805 

 fathoms at Station 2. 



Limatula ovata Jeffreys. 



Lima ovata (Wood) Jeffreys, Ann. Mag. Nat. Hist., Nov. 1876, p. 426. 



A single valve with rather prickly imbricated sculpture on the ribs, a plain 

 hinge-line and no furrow, was obtained by Sigsbee in 450 fins, off Havana. 

 This unfortunately crumbled under handling, but may very probably be re- 

 ferred to the species quoted by Jeffreys under the above name. 



Pectun cuius variegatus (?) D'Orbigny. 

 ? P. variegatus D'Orbigny, Sagra, Moll. Cub., II. p. 314. 



Station 56, 888 fms. 



A single pair from the above locality may belong to the species above men- 

 tioned, which is the P. castaneus of Lamarck. 



It is hoped that in the final report this and other doubtful species will be 

 definitely recognized, — a labor often taking a disproportionate amount of time 

 compared with the result obtained and which could not be at present spared.
