Tlie few roundish ribs are broadest at the lower ends and 

 gradually diminish upwards. The operculum is unguicular, 

 with a groove running lengthwise from the apex, to the superior 

 margin,

This species is allied to P.flavidida^ Lamk. The upper half 

 of each whorl is nearly smooth, as the plications extend 

 scarcely beyond the central large spiral liration which marks 

 the angulation of the whorls. Sometimes, this lira being 

 double, the whorls are less acutely angular. 



Pleurotoma (Drillid) nodilirata. 



Testa fusiformis, turrita, albido-cornea ; anfract. 11, superne con- 

 cave excavati (excavatione arcuate striata), medio obtuse angiilati, 

 infra suturas carina tenuimarginati, infi'a cxcavationem costis ob- 

 Uquis modice validis (in anfr, idtimo circiter 12 basi fere con- 

 tinuis) instructi, liris spiralibus prsecipue super costas elevatis (in 

 anfr. superioribus 5-6, in ultimo circiter 20 subnodulosis) cineti ;

 • totius fere | aequans ; columella recta, crasse callosa ; labrum
