PHOS. 219 



Hinds described this species from a young shell (fig. 527), 

 which, however, agrees well enough with Ph. Gumingii, Reeve 

 (fig. 519). The figures given in Sowerby's Thesaurus (fig. 518, 

 gaudens, fig. 528, Cumingii), differ somewhat, but evidently 

 belong to the same species. I am very doubtful of the propriety 

 of separating this from Ph, articulatus, Hinds ; from which typi- 

 cally it differs in the smaller number of ribs. 



PH, VERAGUENSIS, Hinds. PL 84, figs. 529-532, 534. 



Shell without shoulder, closely covered with narrow, elevated, 

 longitudinal ribs, crossed by narrow, raised revolving lines, 

 forming prickly tubercles at the intersections. Yellowish or 

 brownish, sometimes faintly banded. Length, 1-1'25 inches. 

 Veragua, W. Coast of Central America ; West Indies ; Senegal. 



I cannot detect any difference between the West Coast and 

 West Indian specimens, and accordingly place in the synonymy 

 the following species from the latter area : Ph. Antillarum, Petit 

 (fig. 531) and Ph. Candei, d'Orb. (fig. 534). Ph. Grateloupiana, 

 Petit (fig. 532), said to come from Senegal, may also be placed 

 here. 



PH. BEAUII, Fischer. PL 84, fig. 533. 



Elongate-conical, with numerous slight longitudinal ribs, and 

 occasional revolving lines ; yellowish brown, obsoletely 4-5 

 banded ; whorls occasionally crossed by rounded varices. 



Length, 39 mill. 



Isle of Marie Galante, W. Indies. 



Shell less solid and with much less developed sculpture than 

 the preceding species ; the absence of prickly tubercles being the 

 most important differential character. 



PH. GUADELOUPENSIS, Petit. PL 83, figs. 520, 512. 



Shell broad-ovate, spire conical-turreted ; longitudinal ribs ter- 

 minating in nodules upon the margin of the sloping, usually broad 

 shoulder. White, more or less maculated with brown ; aperture 

 stained with brown within. Length, 1 inch. 



West Indies ; Northern Coast of South America. 



A very common species of the Caribbean province, having 

 much the form of Ph. pallidus, Powis, and Ph. textum, Gmel. 

 In sculpture and degree of development of shoulder there is
