Species 159. (Mus. Taylor.) 

 Mitra Defrancii, Milr. testa lanceolato-ovatd, spird 

 subturritd ; anfractibus superne leoiter angulatis, longi- 

 tudinaliter plicatis,plicis angustis, subcompressis, trans- 

 versim striatic; cinnamomeo-nigricante, lined unicdfla-

 Defrance's Mitre. Shell lanceolately ovate, spire some- 

 what turreted ; whorls slightly angulated at the upper 

 part, longitudinally plaited, plaits narrow, rather 

 compressed, transwr-ely striated; eiimamon black,

 Payrandeau. Cat. Moll, de Corse, p. 1G6. pi. 8. f. 22. 



Mitra ebenus, var. fi, Philippi. 

 Hah. Mediterranean (Corsica, Sicily, &c). 



Tliis species, though intimately allied to the plaited va- 

 riety of the Mitra ebenus, may be always distinguished by 

 its turriculated form, and by the more compressed struc- 

 ture of the plaits.

acuta; anfractibus transversim impresso-striatis, supra 

 et infra plus minusve angulatis, longitudinaliter costa- 

 tis,costis adangulos exasperato-mucronatisj alba, balteo 

 angusto fuscescente inter castas cingulatd; columella

 The ghastly Mitre. Shell ovately turreted, spire sharp ; 

 whorls transversely impressly striated, more or less 

 strongly augulated above and beneath, longitudinally 

 ribbed, ribs sharp-pointed upon the angles; white, 

 encircled with a narrow pale brown belt in the inter- 

 stices between the ribs; columella four-plaited ; in- 

 terior of the aperture striated. 

 Reeve, Pro. Zool. Soc, 1844. 



Hub. Philippine and Lord Hood's Islands (found under 

 stones at low water) ; Cuming. 

 However closely this shell may approximate to the Mitra 

 exasperata it is uniformly white, and always exhibits a 

 strong peculiarity in the band which appears in the inter- 

 stices and not upon the summit of the ribs. 



Species 161. (Mus. Taylor.) 

 Mitra arenosa. Milr. testa ovato-turritd, spira acuta; 

 anfractibus transversim impresso-striatis, longitudina- 

 liter multiliratis, liris parois, confertis, suhgranosis ; 

 albidd, cinereo-ceerulescente fasciatd, litis interdum m- 



gricantibus aut nigricante-punctatis ; columella quad- 

 riplicatd : apertura fauce striata. 

 The sandy MrTRE. Shell ovately turreted, spire sharp ; 

 whorls transversely impressly striated, longitudinally 

 many-ridged, ridges small, close-set, slightly granu- 

 lated ; whitish, banded with ashy blue, ridges somi - 

 times blackish or black-dotted ; columella four-plaited ; 

 interior of the aperture striated. 

 Lamarck, Anim. sans vert. (Deshayes edit.), vol. x. p. 338. 



Mitra torulosa {pars), Kiener. 

 Hob. Island of Ticao, Philippines (found under -in 

 low water); Cuming. 

 M. Kiener regards this species as a variety of the fol- 

 lowing, but I do not think it expedient to follow his opi- 

 nion. One half of the established species may be dispensed 

 with were every one of two that approximate abandoned 

 upon the discovery of their intermediate link. 



Specie-. L62. (Mus. Cuming.)

 The sharp-pointed Mitre. Shell ovately turreted, 

 spire sharp ; whorls decussately impressly striated, 

 angidated round the upper part, longitudinally ribbed, 

 ribs a little compressed ami sharp-pointed at the an- 

 gle; whitish, banded with ashy blue; columella four- 

 plaited; interior of the aperture striated. 

 Valuta exasperata, Chemnitz, Conch. Cab., vol. x. 



p. 172. pi. 151. f. 1440 and 1441. 

 Mitra torulosa, Lamarck. 

 Valuta corrugata, Wood. 

 Hah. Java and the Philippine Islands (found abundantly 

 at Ticao under stones at low water); Cuming. 

 Chemnitz's Valuta cruentata and exasperata, figured in 

 PI. 151. vol. x. of the ' Conchylien Cabinet,' seem to have 

 quite escaped the attention of Lamarck and his followers, 

 the former having been described under the new name of 

 Mitra Iturpoeformis, the latter under that of Mitra torult s« 



Species 163. (Fig. Swainson.) 

 Mitra carinata. Mitr. testa fusiformi, spird turritd ; 

 anfractibus, superne subangulatk, supra transversim im- 

 presso-striatis, infra lavibus ; olivaceo-fuscd ,- columella 

 quadriplicatd.
