Gray, MSS. (Private cabinet). 



Hah. ? 



iVn interesting species, wliich may readily be distin- 

 guished by its conical form. 



Species 68. (Mus. Cuming.) 



Mangelia Zebuensis. Many, testa, ovato-oblongd, spird 

 acuminata, basi subattenuatd, concentrice fortiter cos- 

 tatd, transversim creherrinie striata; fmcescente. 



The Zebu Mangelia. Shell ovately oblong, spire acu- 

 minated, a little attenuated at the base, concentrically 

 ribbed, transversely very closely striated ; pale brown. 



Reeve, Pro. Zool. See, 1846. 



Hab. Island of Zebu, Philippines (found in sandy mud at 

 the depth of four fathoms) ; Cimiing. 



Of simple structure, but specifically distinct from any of 

 the former. 



Species 69. (Mus. Cuming.) 



Mangelia cincta. Mang. testa snbfusiformi-ovatd, spird 

 turritd, suturis subprofundis ; anfractibus superrie an- 

 gulatis, longitudinaliter costatis, costis distantiius ; al- 

 bidd, anfractibus fascia latd fuscescente superne cinctis. 



The gibdled Mangelia. Shell somewhat fasiformly 

 ovate, spire tmTeted, sutures rather deep ; whorls 

 encircled round the upper part with a broad light 

 brown band. 



Eeeve, Pro. Zool. Soc, 1846. 



Hab. Island of Bohol, Philippines (found under stones at 

 low water) ; Cuming. 



The ribs are unusually distant, and impart a hexagonal 



character to the shell. 



Species 70. (Mus. Metcalfe.) 



Mangelia digitale. Mang. testa fusiformi-ovatd, solidd, 

 undique creberrime granoso-clathratis ; albicante, zonis 

 duabus pnrpureis augustis cingulatd. 



The thimble Mangelia. Shell fusiformly ovate, solid, 

 very closely granosely latticed throughout ; whitish, 

 encircled with two narrow purple zones. 



Keeve, Pro. Zool. Soc, 1846. 



Hah. ? 



The sculpture of this species is very similar to that of 

 the M. solida, represented at Pig. 64. 



Species 71. (Mus. Cuming.) 



Mangelia nana. Mang. testa ovatd, spird brevi, turritd, 

 apice acutd ; anfractibus superne angidatis, longitudi- 

 naliter oblique costatis, interstitiis cavis, subtiliter 

 striatis. 



The dwakp Mangelia. Shell ovate, spire short, tur- 

 reted, sharp at the apex ; whorls angulated round the 

 upper part, longitudinally obUquely ribbed, interstices 

 hollow, finely striated. 



Eeeve, Pro. Zool. Soc, 1846. 



Hab. Island of Mindanao, Philippines (found in sandy 

 mud at the depth of twenty five fathoms) ; Ciuning. 



The spire is of a peculiar short dwarf-like character, 

 though sharp at the apex.
