2 1 6 PHOS. 



I am compelled to refer to this form a considerable number of 

 species which do not appear to me to have distinctive cliaracters : 

 I have figured them all, however, and those who suppose that I 

 am too conservative, will be able tlierebv to form their own con- 

 clusions. P. rauricatulxia^ Gould (fig. 484), from Japan; P. an- 

 gidatus, Sowb. (fig. 485), Philippine Ides : P. sealaroides, A. Ad. 

 (fig. 4S6), habitat unknown ; P. Jilosus, A. Ad. (fig. 487), habitat 

 unknown; Ph. ligatus. A. Ad. (fig. 488), habitat unknown ; P. 

 plicatus, A. Ad. (fig. 489), from Eastern Seas; P. rufofasciatus, 

 A. Ad. (fig. 490), PhiHppineH: F. fasciatus, A. Ad. (fig. 575), 

 Philippines ; P. texlihs. A. Ad. (figs. 492, 493). Philippines; 

 P. nodicostatus, A. Ad. (fig. 506), Philippines. 



Vh. Adamsi, Petit. PI. 83, fig. 491. 



Whitish, obscurely fasciated with brown ; regularly caucellaU'd, 



and prickl}' nodose. Length, 1 inch. 



Habitat unk/iown. 

 This appears to be less pyramidni in toim, and differs also from 

 senticosus in its equally prominent longitudinal and revolving 

 sculpture ; still, it may be only a variety. It was described bj' 

 A. Adams as P. cancellatus^ which name being preoccupied, 

 Petit changed it to Ph. Adamsi. 



P. PLicosus, Dunker. PI. 83, figs. 523, 522, 524. 



Ribs rather distant, tubercled at the shoulder of the whorls, 

 encircled by close, sliarp revolving striic ; white, middle of outer 

 lip and base of shell chestnut-brown. Length, 1-2 inches. 



Cape of Good Hope- 



The type is badly figured (fig. 523), yet the description identi- 

 fies it with the subsequently published P. speciosus, A. Ad. (fig. 

 524) and P. Morrissii, Dunker (fig. 522 i. The ribs are somewiiat 

 closer and the shoulder angle not so marked as in P. pallidas, 

 the revolving striae are much finer, and the chestnut coloring 

 appears to be, a constant distinctive character. 



Ph. Cyllenoides, A. Ad. PI. 83, fig. 497. 



liight yellowish brown, with ash-colored revolving bands 

 crossing the ribs. Length, "5 inch. 



Philippines. 



Distinguished by its short, angulated form, few and prominent 

 ribs, wide shoulder, etc.
