 The long-tailed Ranella. Shell triangularly elon- 

 gated, Murex-shaped, whorls sharply angulated at 

 the upper part, transversely ribbed, longitudinally 

 plicately noduled ; ashyoliveor slate- colour ; colu- 

 mella smooth, canal rather elongated ; lip pecu- 

 liarly denticulated ; aperture small, interior black- 

 ish or dark purple-brown. 

 Say, American Conchology, pi. 48. 



The Ranella caudata duo not appear to be at all 

 known to continental conchulogists ; Pi'eirfer ventures to 

 quote it as synonymous with the Ranella Mttriciformis, 

 whilst Kiener has figured a shell for it (vide Triton 

 ficoides) to which it has no reference whatever, though 

 Mr. Say's representation is abundantly characteristic.

The rose-mouth Ranella. Shell ovately turbinated ; 

 spire acuminated ; whorls angulated at the upper 

 part, transversely and longitudinally strongly ribbed, 

 ribs, the upper rib especially, strongly tuberculated, 

 tubercles granulated in a crisped manner, a single 

 row of granules running between the ribs; whitish 

 yellow, punctured here and there with pink ; colu- 

 mella excavated, bright rose-colour, granulated, 

 wrinkled at the upper and lower parts ; aperture 

 round, slightly sinuated above and below ; lip den- 

 ticulated within, rose-tinted.

Hub. Islands of Capul and .Masbate, Philippines; Cuming. 

 An interesting and very distinct species. 



Species 33. (Mus. Saul.) 

 Ranella plicata. Ran. testa ob/ongti, sub-Muricifonni; 

 anfractibus raluiidiilis, sculiris, lonijitudinaliter plica- 

 /is, in medio nodulosis ; livido-olivaced, zond albidd

The plicated Ranella. Shell oblong, somewhat 

 Murex-shaped ; whorls rounded, rough, longitudi- 

 nally plicated, noduled round the middle ; livid 

 olive-colour, encircled round the middle with a 

 narrow white zone ; columella smooth, canal long.

Ha/,. ? 



The plicated growth of this shell is developed with 



the neatest regularity from the apex to the margin. 



Species 34. (Mus. Cuming.)

 The Murex-shaped Ranella. Shell elongately Murex- 

 shaped, flatly triangular ; varices rather wide, pin- 

 nated ; whorls angulated at the upper part, tuber- 

 cled or subfoliated on the angle, elevately striated, 

 striae rather remote ; columella smooth, canal long. 

 Broderip, Pro. Zool. Soc, 1832. 



Hub. Bay of Montija, West Columbia (found in loose 

 gravel at the depth of seven fathoms) ; Cuming. 

 This species may be distinguished by the flatly ex- 

 panded pinnated character of the varices. 



Species 35. (Mus. Belcher.) 

 Ranella pectinata. Ran. testd e/ongalo-Muricifonni, 

 spirit acuminata ; varicibus obliijuis, muricato-spino- 

 sis ; anfraclilius transrersim lira/is, superni leeiter

 titis ; columella hem ', ; canali elongato, recto; aper- 

 turd ovali, labro intus obsolete denticulato. 

 The pectinated Ranella. Shell elongately Murex- 

 shaped, spire acuminated ; varices prickly spined ; 

 whorls transversely ridged, slightly angulated at 

 the upper part, tuberculated on the angle, tuber- 

 cles bipartite ; columella smooth ; canal elongated, 

 straight ; aperture oval, lip obsoletely denticulated 

 within.

 Hub. San Bias, Mexico (in seven fathoms mud) ; Hinds. 

 An interesting addition to the genus Ranella, having 

 very much the form of those species of the genus Mures 

 familiarly known as the " snipes " or " woodcocks."
