 PH. PALLIDUS, Powis. - PL 83, figs. 494-496. 



Whitish, yellowish or fuscous, usually darker between the 

 longitudinal ribs, color sometimes broken up into revolving 

 series of spots (Ph. notatus, Sowb., fig. 496). Length, 1 inch. 



Panama ; Philippines ? 



A stout, ovate, rugose species, with prominent nodulated 

 shoulder and Nassa-like form. Ph. pallidus is known to come 

 from Panama, yet it is recorded " Philippines " in Sowerby's 

 Thesaurus. Ph. notatus is also " Philippines " in the same work, 

 and I do not think the locality can be correct in either case.
