Species 32. (Mus. Cuming.)

 dMantibus, conceutrke dkposiUs ; siiiu laUuscido ;

 truncated at the base, longitudinaOy ribbed, ribs thin, 

 rather distant, concentrically arranged ; sinus rather 

 broad; white, with somewhat square orange-brown

Reeve, Pro. Zool. Soc., 1846. 



Hab. Island of Ticao, Phibppines (found under stones at 

 low water) ; Cuming. 



The orange-browu spots which constitute one of the 

 distinguishing features of this species are very characte- 

 ristic on the last whorl, but on the upper whorls only the 

 upper portion of them remain visible. 



Species 23. (Mus. Cuming.) 



Mangelia turricula. Mang. testd fusiformi-turritd, 

 suturis profundis; anfractibus plaito-dejiressis, longitu- 

 diualiter concentrice costatis ; albicmtte, liueis subtiUs- 

 simis aurantio-fuscis obsolete cingidatd. 



The little tower Mangelia. Shell fusiformly tur- 

 reted, sutiu'es deep ; whorls flatly depressed, longitu- 

 dinally concentrically ribbed ; whitish, obsoletely en- 

 circled with very fine orange-brown lines. 



Eeeve, Pro. Zool. Soc, 181.6. 



Hab. Island of Ticao, Philippines (found on the sand); 

 Cuming. 



The orange-browu lines above described are too faintly 

 indicated to be represented in the figure, indeed they are 

 but just (bscernible with the lens. 



Species 24. (Mus. Ctmiing.) 



Mangelia Columbelloides. Mang. testd ovatd, spird 

 brevi, acutd; anfractibus superiie leviter rotundatis, 

 transversim elevato-striatis, longitudinaliter temiicos- 

 tatis, labro medio tiimido, intus fortiter denticulato ; 

 nimd, costis eximie aurantio-fusco punctatis. 



The Columbella-like Mangelia. Shell ovate, spire 

 short, acute; whorls slightly rounded at the upper 

 pai-t, tranversely elevately straited, longitudinally 

 finely ribbed, lip swollen in the middle, strongly den- 

 ticulated within ; snowy wliite, ribs delicately dotted 

 with orange-brown. 



Reeve, Pro. Zool. Soc, 1846. 



Hab. Baclayon, Island of Bohol, Philippines (found on 

 mud banks) ; Cuming. 

 An extremely interesting species distinguished by its 



Columbella-Uke structiu'e, and faint dotted colouring of 



the ribs. 



Species 25. (Mus. Cuming.) 



M.\NGELIa Conohelicoides. Mang. testa ovato-conicd, 

 spird brevissimd, acutd; anfractibus transversim elevato- 

 striatis, longitudinaliter multiliratd, liris tenuibus, ante 

 mtturas evanidis ,- luteo-albicante, dorso macula grandi 

 anrantio-fuHcd interdum tincto. 



The Conohelix-like Mangelia. Shell ovately conical, 

 spire very short, acute ; whorls transversely elevately 

 striated, longitudinally many-ridged, ridges thin, 

 fading before the sutm-es ; yeUowish-wliite, back 

 sometimes stained with a large orange-brown blotch. 



Reeve, Pro. Zool. Soc, 1846. 



Hab. Daleguete, Isle of Zebu, Philippines (found imder 

 stones); Cuming. 

 Di.stingidshed by that pecidiar conical form, which is 



tjfpified in the Mitres, separated by Mr. Swainson under 



the title of Conolielix. 



Species 26. (Mus. Cuming.) 



Mangelia tenebeosa. Mang. testd subfusiformi, spird 

 acuminato-turritd; anfractibus superne plano-depressis, 

 suturis profundis, transver-unt striatis, longitudinaliter 

 costatis, costis distanfibus ; intus extusque cadaneo- 

 fuscd. 



The dark Mangelia. Shell somewhat fusiform, spire 

 acuminately tm'rited ; whorls flatly depressed at the 

 top, sutiu-es deep; transversely striated, longitudinally 

 ribbed, ribs distant ; dark ehesnut brown within and
