MANGELIA.— Plate TI. 



zoned painting is most conspicuous on the back of the last 

 whorl, where it forms a rude blotch. 



Species 13. (Mus. Cimiing.) 



Mangelia lamellata. Many, testa fmiformi-ovatd, 

 spirce suturisprofundis, subcavernosis, anfractibim trans- 

 versim elevato-striatis, siriis fortibus, subdistantibtis, 

 loitgitudinallter costatis, cosfis angustu, erectis, tamel- 

 laformibus, superne leviter mucronatis ; albidd, fusco 

 pallidissime zonatd. 



The iamellated JIangelia. Shell fusiformly o\ate, 

 sutures of the spire deep, a little cavernous ; whorls 

 transversely elevately striated, strise strong, rather 

 distant, longitudinally ribbed, ribs narrow, erect, 

 lameUa-like, slightly pointed at the top ; white, zoned 

 with very pale brown. 



Eeeve, Pro. Zool. Soc, 1846. 



Eab. Isle of Burias, Philippines (found among coarse sand 

 at the depth of seven fathoms) ; Cuming. 



Chiefly distinguished by the narrow elevated lameDa-Iike 

 character of the ribs. 



Pig. 13. (Mus. Cuming.) 

 Mangelia geacilis. Far. /3. I had figured this shell 



as a species distinct from the M. gracilis, but upon 

 fm'ther examination, am inclined to flunk that it is 

 merely a variety, «ith the transverse stria; moi-e 

 strongly developed, and the longitudinal ribs less so. 

 Por Species 13 see Plate V. 



Species 14. (Mus. Cuming.) 



Mangelia vittata. Mang. testa oltongo-ovatd, siibco- 

 tticd, spird brevi, obtnsd ; anfractibits longitudhmtiter 

 costatis, costarum interstitiis striis fortibus clathratus ; 

 albidd, oUvaceo-fusco latifasciatd, costarum parte oli- 

 vaceo-fnscd albipunctatd, 



The riband-bound Mangelia. Shell oblong-ovate, 

 somewhat conical, spire short, obtuse ; whorls longi- 

 tudinally ribbed, interstices between the ribs latticed 

 with strong strife ; whitish, encu'cled with broad 

 olive-brown bands, the coloured portion of the ribs 

 being dotted with white. 



Eeeve, Pro. Zool. Soc., 1846. 



Hah. Island of Ticao, Philippines (foimd on the sands) ; 

 Cuming. 



An interesting species so distinct from any other I have 

 met with, that it may be recognised mthout difficulty.
