MITRA.— Plate XIII. 



Two fine specimens of this peculiarly grooved species 

 were collected at the above-named localities by Captain 

 Belcher ; one, for the drawing of which I am indebted to 

 Mr. Hinds, in his own collection ; the other, which has 

 furnished me with the above description, in that of 

 Thomas Morris, Esq. 



Species 94. (Mus. Cuming.) 



Mitra polita. Mitr. testa acuminato-turritd, levigatd, 

 politd, ait basim sulcatd, prope apieem subtilissime 

 plicato-costatd ; fused vet cinereo-fuscd, lined unicd

The polished Mitre. Shell acuminately turreted, 

 smooth, polished, grooved at the base, very finely 

 plicately ribbed near the apex; brown or ashy brown, 

 encircled with a single pale yellowish belt ; colu- 

 mella four-plaited.

Iliih. Islands of Zebu and Luzon, Philippines (found in 



mud on the shore at low water, and at the depth of 



six or seven fathoms) ; Cuming. 



At the desire of one or two gentlemen whose opinions 



in conchological matters cannot be lightly esteemed, I 



have described the Mitra polita and crebrilirata as new 



and distinct species ; it must be admitted, however, that 



I have felt strongly tempted to regard the former as the 



Eastern analogue of the Mitra ebenus, smooth variety, of 



the Mediterranean, and the latter as the analogue of the 



Mitra ebenus, ribbed variety, of the same region. 



Species 95. (Mus. Cuming.) 

 Mitra variabilis. Mitr. testa oblongo-ovatd, medio 

 subobesd, Imvigatd, transversim subtilissime punctato- 

 striutd ; liilesccnle-oUvaced, lineis fuseis capillaribus 

 remotiusculis cinctd, anfractu ultimo zond unicd cieru- 

 lescente-albd medio ornato ; columella quadriplicatd ; 

 apertures fauce olivaceo-fuscd. 

 The variable Mitre. Shell oblong-ovate, rather stout 

 in the middle, smooth, transversely very finely 

 striated with punctures ; yellowish olive, encircled 

 with rather distant brown hair lines, last whorl or- 

 namented with a single blueish white zone round 

 the middle ; columella four-plaited ; interior of the 

 aperture olive-brown.

Hub. Torres Strait (found under stones at low water) ; 

 Dring. 

 The variable character of this species consists in its 

 being sometimes flaked or indistinctly streaked with 



Species 96. (Mus. Cuming.) 



Mitra striatila. Mitr. testa acuminato-ovatd, Itevi- 



gatii , striis lineisvelevitere/evatisclegantissime cinctd; 

 lutescente-olivaeed, maculis a/liidis perpaucis irregu- 

 lariter conspersd ; columella quinqueplicatd ; aper- 

 tures fauce olicaceo pallide ti/ictd. 



The finely striated Mitre. Shell acuminately ovate, 

 smooth, very elegantly encircled with slightly raised 

 lines or striae ; yellowish olive, sprinkled here and 

 there with a very few white spots ; columella five- 

 plaited ; interior of the aperture faintly stained with 

 olive. 



Lamarck, Anim. sans vert., vol. vii. p. 313. 



Hub. Island of St. Vincent, West Indies (found on the 

 coral reefs) ; Guilding. 

 The fine transverse strise of this shell are of a very 



peculiar character, slightly raised, and of rather a darker 



colour than the intermediate ground. 



Species 97. (Mus. Cuming.) 



Mitra cylindracea. Mitr. testa cylindraceo-ovatd, 

 utrinque attenuatd, sulcis capillaribus puncturatis, 

 superne remotiusculis, cingulatd ; lutescente-olivaeed, 

 maculis alius irregularibus infra suturas ornatd, an- 

 fractu ultimo in medio maculato-fasciato ; columella 

 quadriplicatd ; aperture fauce fuscescente. 



The cylindrical Mitre. Shell cylindrically ovate, at- 

 tenuated at each end, encircled with punctured hair- 

 like grooves rather distant towards the upper part : 

 yellowish olive, ornamented beneath the sutures 

 with irregular white spots, last whorl with an in- 

 terrupted band of spots round the middle; colu- 

 mella four-plaited ; interior of the aperture light 

 brown.

Hah. ? 



The painting of this shell is not much unlike that of 



the Mitra variabilis.
