CASSID^E 



CASSIDARIA Lamarck 



Shell ventricose, not varicose ; canal long, twisted, reverted, or 

 bent sidewise; inner lip greatly expanded; outer lip reflected, 

 often crenulate ; columella border plicate. Upper Cretaceous to 

 Recent, maximum in the Eocene. (Zittel.) 



Cassidaria echinophora Linn. ( ?) Plate IV, fig. 5. 



Sacco, Moll. Terz. ael Piemonte, pt. XXX, PI. XXI, fig. 3. 



I have compared this with a specimen from the Astian (middle 

 Pliocene) of Italy, in the British Museum collection. The living 

 form in the same collection is different, the chief difference being 

 in the matter of teeth on the inner side of the lip. The prom- 

 inent tooth near the upper portion of the lip in the Philippine 

 form is lacking in the recent shell and the tubercles are more 

 pronounced in the former. 



Locality: Cut in road between Laoag and Bacarra, Ilocos 

 Norte, Luzon. 



Formation: Recent sandy marl. 



CASSIS Lamarck 



Shell ovoid, ventricose, having irregular varices; spire short, 

 aperture elongate; outer lip thickened, reflected, usually denti- 

 culate in the interior; inner lip callous, expanded, denticulate, 

 wrinkled, <5r granulate ; canal very short, broad, sharply recurved, 

 directed upward posteriorly. Tertiary and Recent. (Zittel.) 



Cassis pila Reeve. Plate V, fig. 6. 

 Tryon, Conchology, 7, figs. 76, 77. 



The form figured here and referred to C. pila is an imperfect 

 cast, but sufficiently recognizable I think to be identified as this. 



Locality : Constabulary Hill, in quarry at bottom of hill, Cota- 

 bato, Mindanao, No. 293. 



Formation: Limestone. 



Cassis nodulosa Gmelin. Plate V, fig. 7. 



This is a very recent form, and resembles closely a specimen in 

 the British Museum collection marked "Her Majesty the Queen." 



Locality: Bongao, Tawi Tawi, No. 970. 



Formation : Recent, raised beach.
