Species 89. (Mus. Norris.)

 acuminatd, transversim subtilissime striatd; albidd, 

 lineis capillaribus fuscescentibus remotiusculis cingu- 

 latd, maculisgrandibusustulato-fuscis nebulosd; colu-

 minated, transversely very finely striated ; whitish, 

 encircled with rather distant hrown hair lines, and

Reeve, Pro. Zool. Soc, 1844. 



Hah. ? 



This species is at present unique in the collection of 



Thomas Norris, Esq. 



Species 90. (Mus. Cuming.) 



Mitra lactea. Mitr. testd abbrcviato-fusiformi, la-ei- 

 gatd, transversim sultilissim'e punctato-striatd ; iu- 

 tus extusque lacted ; columelld quadriplicatd ; labro 

 effuso. 



The milk-white Mitre. Shell abbreviately fusiform, 

 smooth, transversely very finely striated with punc- 

 tures ; milk-white within and without ; columella 

 four-plaited ; lip effused. 



Lamarck, Anim. sans vert., vol. vii. p. 312. 

 Valuta cornieularis, ear., Chemnitz. 



Hab. Mediterranean, coast of Sicily ; Philippi. 



This species, as Lamarck concluded, is quite distinct 



from the Mitra cornieularis. 



Species 91. (Mus. Cuming.) 



Mitra abbatis. Mitr. testd ovato-fusiformi, anfrac- 

 tibus contiguis, ultimo ad liasim contracto ; albd, 

 maculis ferrugineis peculiuriter pictd ; columella 

 quadriplicatd ; aperturte fauce pallidissime aurantid. 



The abbot's Mitre. Shell ovately fusiform, whorls 

 contiguous ; white, peculiarly painted with rusty 

 brown spots ; columella four-plaited ; interior of 

 the aperture faintly tinged with orange. 



Chemnitz, Conch. Cab., vol. xi. p. 19. pi. 177. fig. 1709 

 and 1710. 

 Mitra contractu, Swainson. 



Hab. Matnog, island of Luzon, Philippines (found on 

 the reefs) ; Cuming. 



Care should be taken not to confound this excellent 

 species with the Mitra ehrysostoma, a specimen of which 

 has been figured for it by M. Kiener. The Mitra abbatis 

 is a narrower and uniformly smaller shell than the Mitra 

 ehrysostoma, the whorls of the spire are more contigu- 

 ous, and have no longitudinal grooves to give it any 

 granular appearance ; the style of painting is moreover 

 distinct. The contiguous arrangement of the whorls 

 reminds one of the movement of a telescope. 



Species 92. (Mus. Norris.) 



Mitra crebrilirata. Mitr. testa acuminato-turritd. 

 loncjitudiiiuliter suboblique liratd, liris angustis, cre- 

 bris, inters/itiis impresso-cance/latis ; olivaced vel 

 olivaceo -fused, lined unicd pallida infra suturas pit - 

 rumque einctd ; columelld quadriplicatd. 



The close-ridged Mitre. Shell acuminately turreted. 

 longitudinally rather obliquely ridged, ridges nar- 

 row, close, interstices impressly cancellated ; olive 

 or olive-brown, generally encircled beneath the 

 suture with a single pale line; columella four- 

 plaited. 



Reeve, Pro. Zool. Soc, 1844. 



Mitra rosea, Kiener (not of Duclos). 



Hab. Ceylon. 



Figured by M. Kiener for the Mitra rosea of Duclos, 

 which is the Valuta ignea of Wood, Mitra subulata of 

 Lamarck, for which see Plate XI. fig. 79. 



Species 93. (Mus. Belcher). 



Mitra Belcheri. Mitr. testd elongato-turritd, spird 

 raid? productd, sulcis angustis, exarato-exseulptis 

 undique cingulatd ; albidd, epidermide corned fusco- 

 nigrieante i/idutd ; columelld quadriplicatd. 



Belcher's Mitre. Shell elongately turreted, spire very 

 much produced, encircled throughout from the base 

 to the apex with narrow deeply cut grooves ; 

 whitish, covered with a horny brownish black epi- 

 dermis ; columella four-plaited.

Hah. Gulfs of Nicoya and Papagayo, Central America 

 (dredged from a muddy floor at the depth of seven- 

 teen fathoms) ; Hiuds. 



September 1844.
