 Hub. Panama, coral sand, 6 to 10 fathoms ; H. C. 



13. Phos textilis, A. Adams. P. testa elongate ovatd, albidd, 

 spird acutd, costis rotundatis, crassis, infra s^ituram nodoso- 

 angulatis, lineis transversis, plants, suhconfertis, elevatis, inter- 

 stitiis longitudinaliter subtilissime striatis ; columelld plied 

 anticd validd. 



Hab. Dumaguete, Philippines ; //. C. 



In general form this species approximates P. Blainvillii, but the 

 elaborate and distinct style of sculpture and white aperture at once 

 distinguish it. 



14. Phos rufocinctus, A. Adams. P. testd ovato-fusiformi ; 

 spird productd, angustd, albidd, fascid rufd ornatd ; anfracti- 

 bus rotuyidatis, costis crassis, infra suturani rotundatis, lineis 

 transversis, elevatis, nodulosis, confertis, ornatis ; columelld 

 plied anticd productd. 



Hab. Dumaguete ; //. C 



The nucleus of this species is large and papillary. 



15. Phos scalarioides, A. Adams. P. testd ovatd, acuminatd, 

 turritd, albidd, fusco variegatd, obscure fusco bifasciatd ; an- 



fractibus rotundatis, costis longitudinalibus, distantibus, infra 

 suturam rotundatis, lineis elevatis, transversis, ad suturas no- 

 dulosis, interstitiis subtilissime longitudinaliter striatis ; colu- 

 melld supernh callosd, inferne plied productd ; labro intus 

 lirato. 



Hab. ? 



A beautiful species, with regular, strong ribs, giving it the appear- 

 ance of a Scala7'ia. 



16. Phos spinicostatus, A. Adams. P. testd ovatd, spird acu- 

 minatd, albidd, sparsim fusco nebulosd; anfractibus rotundatis, 

 costatis, costis distinctis, subdistantibus, infra suturam angu- 

 latis et spinosis, lineis transversis elevatis ornatis; columelld 

 rufo-fusco maculatd, plied anticd productd ; labro intus rufes- 

 centi lirato. 



Hab. Batangas, in insulis Philippinis. 



17. Phos nodicostatus, A. Adams. P. testd ovatd, turritd, 

 acujninatd, albidd, rufo-fusco maculatd; anfractibus rotundatis, 

 costatis, costis distantibus, infra suturam angulatis et nodosis, 

 lineis transversis, elevatis, ad costas nodulosis ornatis ; colu- 

 melld plicis evanidis, plied anticd validd productd. 



Hab. ad insulam Negros ; //. C. 



The two species, described above, are somewhat similar in form, 

 but the peculiarity of the ribs and colour of the apertures readily 

 distinguish them. 



18. Phos cyllenoides, A. Adams. P. testd ovatd, albidn- 

 fuscd, spird acutd, longitudinaliter plicato-costatd, costis su- 

 pernh nodosis, ad suturam evanidis, lineis impressis transver-
