Species 29. (Mus. Cuming.) 



Mitra inquinata. Mitr. testd fusiformi-oblongd, sub- 

 angustd, spird acuminata, transversim impresso- 

 striatd, striis pa net urat is ; eburned, rubido-fusco lon- 

 gitudinaliter inquinata ; columella quadriplicatd. 



The smeared Mitre. Shell fusiformly oblong, rather 

 narrow, spire acuminated, transversely impressly 

 striated, stria; punctured ; ivory-white, longitudi- 

 nally smeared with reddish brown ; columella four- 

 plaited. 



Reeve, Pro. Zool. Soc, 1844. 



Hab. ? 



Though a species of very simple character, it is quite 

 distinct from any hitherto described. 



Species 30. (Mus. Drummond.) 

 Mitra fissurata. Mitr. testd cylindraceo-fusiformi, 

 anfractibus leevissimis, nitidis, parte superiori inter- 

 dum longitudinaliter iin/iresso-striatd ; pallide grised, 

 infra cinereo-grised, saturation', totd reticuld alba 

 subtilissimii pietd ; columella quinqueplicatd. 

 The cracked Mitre. Shell cylindrically fusiform, 

 whorls very smooth, shining, upper part sometimes 

 longitudinally impressly striated ; pale grey, darker 

 ashy grey beneath, the whole covered with a very 

 delicate white net-work ; columella five-plaited. 

 Lamarck, Anim. sans vert., vol. vii. p. 311. 

 Hab. Islands of Mauritius and Zanzibar, east coast of 

 Africa ; Thorn. 

 Lamarck likens the delicate net-work of this beauti- 

 ful shell to the fine hair- like cracks in old china ; the re- 

 semblance is not however a very forcible one; a more ap- 

 propriate name might have been selected without much 

 difficulty. 



Species 31. (Mus. Cuming.) 

 Mitra gracilis. Mitr. testd elongatd, spird va/di pro- 

 ductd, suturis subprofundis ; anfractibus transversim 

 subtilissime costatis, costis angustis irregularibus, in- 

 terstitiis liris obtusis minutissimis pulcherrime decus- 

 satis ; albidd, fuscescente pallide fasciald, costis 

 fusco articiilatis ; columella quadriplicatd. 

 The slender Mitre. Shell elongated, spire strongly 

 produced, sutures rather deep ; whorls transversely 

 very finely ribbed, ribs narrow, irregular, interstices 



beautifully decussated with minute obtuse ridges ; 



whitish, very faintly banded with a brownish tint. 



ribs articulated with brown ; columella four-plaited. 

 Reeve, Pro. Zool. Soc, 1S44. 

 Hab. Island of Ticao, Philippines (found in sandy mud 



at the depth of six fathoms) : Cuming. 



A most delicately sculptured shell, with somewhat the 

 character of the Mitra granatina about it. 



Species 32. (Fig. Zool. Illus.) 



Mitra strigata. Mitr. testd ovato-oblongd. lam, ru- 

 bido-fuscd, strigis juxta suturas albis subdistantibus 

 longitudinaliter ornatd ; columella quadriplicatd. 



The streaked Mitre. Shell ovately oblong, smooth, 

 reddish brown, ornamented with rather distant lon- 

 gitudinal streaks, white next the sutures ; colu- 

 mella four-plaited.

 Illustrations, Second Series. 



Hub. ? 



A slight indication of the white streaked character of 



this species may sometimes be observed in the following. 



Species 33. (Mus. Cuming.) 

 Mitra nigra. Mitr. testd acuto-ehmgata, Melan'mformi. 

 laivi ant mi/iutissimr striato-dca/ssutii ; anfractibus 

 plauo-conce.ris, olicaceo-brunneis , juxta suturas indi- 

 stincfe albipunctatis ; columella quadriplicatd. 

 The black Mitre. Shell shaqjly elongated, Melania- 

 shaped, smooth, or very minutely decussated with 

 striae ; whorls flatly convex, dark olive-brown, in- 

 distinctly dotted with white next the sutures ; co- 

 lumella four-plaited. 

 Valuta nigra, Chemnitz (not of Quoy), Conch., 



vol. x. p. 168. 

 Mitra Melaniana, Lamarck. 

 Mitra carbonaria, Swainson. 

 Hab. Island of Annaa, Pacific Ocean (found on the reefs 

 at low water) ; Cuming. 



This species, though of rare occurrence, appears to 

 be very widely distributed throughout the globe, if we 

 may rely upon the localities quoted by Lamarck in ad- 

 dition to that above noted, namely, the coasts of Guinea. 

 India and Greenland.
