Species 205. (Mus. Taylor.)

 laribus aspcrsa, lavigatd, nitente, spird brevi, anfrac-

The double-toothed Columbella. Shell ovate, some- 

 what inflated, transparent-yellow, sprinkled with an- 

 gular red and opaque-white dots, smooth, shining, 

 spire short, whorls a little slanting round the upper 

 part, then rounded, apex blackish ; aperture oblong, 

 denticulated on both sides, columella double-toothed 

 within, lip slightly notched at the upper part.

Hah. Swan Eiver. 



This elegant species is curiously distinguished by the 

 presence of two small teeth on the inner surface of the 

 columella. 



Species 206. (Fig. 206 and 307, Mus. Cuming.) 



Columbella picata. Col. tedd conoided, undiqm spi- 

 ralUer tetmiliratd, purpureo-nigrd pel caslaned, punc- 

 tis opaco-albis in nmculis triaiigularibus et in strigis 

 pronmcuis notatd, spird parm, miicronatd, anfractibus 

 superne obese rotundatis, versus basin attenuatis ; aper- 

 turd elongatd, angustd,fauce carulescente, labro intus 

 superne subascendente, obsolete denticnlato. 



The pied Columbella. Shell conoid, spirally finely 

 ridged throughout, purple-black or chestnut, marked 

 with trianglar blotches of opaque-white dots and pro- 

 miscuous streaks, spire small, pointed, whorls obesely 

 rounded at the upper part, attenuated towards the 

 base ; aperture elongated, narrow, interior bluish, lip 

 slightly ascending at the upper part, obsoletely den- 

 ticulated within.

Columbella ovulafa, Sowerby. 

 Columbella varia, Sowerby. 



Hafi. Australia. 



The two shells represented at Fig. 206 and 209, in- 

 tended to illustrate Mr. Sowerby's C. ovulata and varia, 

 prove to be one and the same species, and the type of Mr. 

 Swainson's genus' Coiiella. The conical Strombus-liVe 

 species, which have been confounded by some writers with 



this subgeneric division of the ColumbellrB, I propose to 

 arrange under a new genus, with the name of Mela. 



207. (Fig. a, b, c, Mus. Cuming.) 



Columbella Pbilippinauum. Col. testa conoided, cras- 

 sd, alba, purpureo-fusco strigatd et fasciatd, spird 

 brevi, acuta, anfractibus superne gibboso-angulaiis, de- 

 inde subconcavis, anfractu ultimo ad basin recurro et 

 spiraliter sulcato ; aperturd elongatd, angusld, labro 

 snbincrassato, superne subascendente, intus obsolete 

 deidiculato. 



The Philippine Columbella. Shell conoid, thick, 

 white, streaked and banded with purple-brown, spire 

 short, sharp, whorls gibbously angled round the 

 upper part, then slightly concave, last whorl recurved 

 and spirally grooved at the base ; aperture elongated, 

 narrow, lip rather thickened, slightly ascending at 

 the upper part, obsoletely denticulated within.

 Coiiella Philippinarum, Adams. 



Httb. Philippine Islands; Cuming. 



This species would also belong to Mr. Swainson's genus 



Conella, by reason of the ascending tendency of the outer 



lip, as distinguished from the decided conical species which 



constitute my genus Mela. 



Species 208. (Fig. c, b, Mus. Cuming.) 

 Columbella discoes. Col. testd cijlindraceo-conoided, 

 ItBvigatd, vivide castaned, inferne albo-punctatd, superne 

 albimaculatd, maculis grandihus, distantibus, spird ob- 

 tuse globosd, apice elevato, mucronato ; aperturd elon- 

 gatd, fauce violaced, labro subinarassato, superne as- 

 cendente, intus obsolete denticulato. 

 The diffeking Columbella. Shell cylindrically co- 

 noid, smooth, bright-chestnut, white-dotted below, 

 white-blotched above, blotches large and distant, spire 

 obtusely globose, apex raised, pointed ; aperture elon- 

 gated, violet in the interior, lip somewhat thickened, 

 ascending at the upper part, obsoletely denticulatec^

This fine and long-known species belongs also to the 

 Conella division of Columhella, as well as its very near ally 

 C. splendidula, and a few other species.
