cancellata, sed costis longitudinalibus magis prsestantibus ; spira 

 elevata ; apertura breviuscula ; labio exteruo sinuato ; canali 

 brevi, recto. — Almost cancellated as in P. cancellalus, but the 

 longitudinal ribs are the most prominent. Hab. ? 



24. Blainvillei (f. 42, 43), Deshayes, Chemn. pi. 125. f. 

 1201, 1202.- — P. testa breviter ovali, alba, costis crebris dis- 

 tinctis ad angulum anfractuum nodosis longitudinalibus et 

 costellis ad costas subnodosis cancellata ; spira breviuscula ; an- 

 fractibus angulatis; apertura fusco et aurantio tincta; canali 

 brevissimo, aperto. A white cancellated species, with orange 

 mouth. The last whorl rather large. Philippines, Cuming. 



25. varians (f. 24-27), Sowb. Th. — P. testa ovata, alba, fasciis 

 et maculis fuscis seu aurantiis variegata, longitudinaliter crebre 

 costulata, spiraliter sulcis impressis subevanidis cincta ; anfractu 

 ultimo raagno ; apertura parva, fusco seu aurantio tincta. — I think 

 the sculpture and form of these varieties sufficiently distinct from 

 those of the true P. Blainvillei to justify their separation. Phi- 

 lippines, Cuming. 



26. cyanosto.ua (f. 46), A. Ad. Pro. Zool. Soc. 1S50.— P. 

 testa quam P. Blainvillei spira magis elevata, ultimo anfractu 

 breviori, costis magis nodulosis. — Differing from P. Blainvillei 

 in its more lengthened spire, and the last whorl being shorter. 

 The ribs are more nodulous. Philippines, Cuming. 



27. spinicostatus (f. 44, 45), A. Ad. Pro. Zool. Soc. 1850. — 

 P. testa unifasciata, quam P. Blainvillei spira. magis elevata, 

 costis magis distantibus, interstitiis pallide purpureis, costis ad 

 angulum acute nodulosis. — A more coloured shell than P. Blain- 

 villei, with more distant ribs, which are sharply nodulous at the 

 angle of the whorls. Batanzas, Philippines, Cuming. 



28. kodicostatus (f. 47), A. Ad. Pro. Zool. Soc. 1850.— P. 

 testa alba, spiraliter striata, ad angulum anfractuum rubro lineata, 

 oblonga, sparsim varicosa, longitudinaliter costata; costis nodu-

 nodulous ribs. The aperture is without the peculiar brown and 

 orange tint observable in the three preceding species. Island of 

 Negroes, Cuming. 



29. textius (f. 48, 49), A. Ad. Pro. Zool. Soc. 1850.— P. 

 testa pallida, oblonga, longitudinaliter costis validis subdistantibus,
