 ciirvd, eburned, durso transversim uiinnli striata, mnliu

depth of fifty-five fathoms) ; Adams. 



A very characteristic species, elegantly acumiuately 

 beaked at the extremities, and distinguished by a very nar- 

 row aperture owing to the callous swelling of the lip and 

 columella. 



Species 55. (Fig. a, b, Mus. Taylor.) 



Ovulum subreflexum. Ov. testd lanceolato-ovaid, ebur- 

 ned, dorso transrersim minute striata, extremitatibus

The slightly-reflected Ovulum. Shell lanceolately-

Shining-white, with callously-swollen lip and aperture,

The deflected Ovulum. Shell lanceolately-ovate, 

 white, extremities straight, gradually attenuated, lip 

 and columella swollen, excavatcly flattened, com-
