 their larger or smaller size appears to be more or less fortuitous.

TURRITELLID^E 



TURRITELLA Lamarck 



Shell turret shaped; whorls even or arched, longitudinally 

 ribbed or striated; aperture oval or rounded quadrilateral, rim 

 not entire, external lip turned backward and somewhat bent 

 outward. Trias to Recent, maximum in the Tertiary. (Zittel.) 



Turritella terebra Lam. Plate VI, fig. 1. 



Lamarck, Mem. Soc. his. nat. Paris (1799), 74. 



This species is still abundant in Philippine waters. The 

 specimen figured here is really a transition form between T. 

 bantanensis with 3 pronounced ribs and T. terebra with 5 or 6. 

 However, it more closely resembles T. terebra. 



Locality: Excavations in Manila. 



Formation: Alluvial sands, Recent. 



Turritella cingulifera Sow. Plate VI, fig. 2. 



This is much larger than the Javan specimen with which I 

 compared it, but it is clearly the same species. 



Locality: Excavations in Manila. 



Formation: Alluvial sands, Recent.

VICARYA Jenkins 



Shell turreted, whorls spirally marked; below the suture a 

 row of protuberances; canal short and bent backward; inner 

 lip flattened, callous; the outer lip beneath the row of spines
