 As indicated earlier by Cushman (1921, p. 320), there seems to 

 be no specific difference between the species described under the 

 names culter (from the tropical Atlantic) and bengalensis (from the 

 Pliocene of Kar Nicobar [Car Nicobar Island]). 



The species is distinguished by its sharp and serrated keel and its 

 characteristic aperture in the form of an elongate narrow opening 

 set at right angles to the base of the apertural face. Number of 

 chambers per final whorl varies between 7 and 11 with most speci- 

 mens having 9 to 11. 



The species occurs rarely and is found only in the deeper samples. 



Genus LAMARCKINA Berthelin, 1881 



LAMARCKINA sp. 



Plate 5, Figure 4 



A single specimen, here illustrated, was found at Albatross station 

 H3798, 687 fathoms, in the Marquesas Islands. Since it appears not 

 to fit any described species, it is left unidentified. Compared with 

 most other specimens in this genus, it is compressed and the dorsal 

 surface is nearly flat and very little arched. The sutures are indistinct, 

 and the umbilicus is broad and deeply depressed.
