Species 34. (Mus. Norris.) 

 Mitra orientalis. Miff, testa ovatd, spirdbrevi, apicem 

 versus plus mimsve erosd ; anfractibus ventricosis, 

 transversim minutissime striatis ; alhhlo-fuscescente, 

 epidermide corned nigerrimd omnino indutd ; aperturd 

 ovatd ; columella quadriplicatd, ccerulescente-albd ;

 Mitra maura, Swainson. 

 Mitra Chilensis, Kiener. 

 Hab. Iquiqui, Peru (found in the fissures of rocks at low- 

 water mark buried in sand) ; Cuming. 

 A shorter and more ventricose species than the pre- 

 ceding, with a very characteristic jet-black epidermis. 



Species 35. (Mus. Cuming.) 



Mitra scabriuscula. Mitr. testd oblongo-ovatd, spird 

 acuminatd ; anfractibus transversim costatis, costls 

 parvulis, angustis, crenuiatis, interstitiis minutissinie 

 plano-liratis, sulcis lineisve impressis confertis longi- 

 tudinaliter decussatis ; ttlbd, fusei'scente subindistincte 

 bifasciatd, costis J'usco irregulariter articulutis ; co- 

 lumelld quadriplicatd; apertures fauce albd. 



The rough Mitre. Shell oblong-ovate, spire acumi- 

 nated ; whorls transversely ribbed, ribs very small, 

 narrow, crenulated or beaded, interstices very mi- 

 nutely flatly ridged, decussated with close-set lon- 

 gitudinal grooves or impressed lines ; white, encir- 

 cled with two somewhat indistinct light brown 

 bands, ribs irregularly articulated with brown ; co- 

 lumella four-plaited ; interior of the aperture white.

Voluta scabriuscula, Linnseus, Syst. Nat., 12th edit., 

 p. 1192. Chemnitz, Conch., vol. xi. p. 28. 

 pi. 172. f. 1729 and 1730. 

 Mitra granatina, Lamarck. 



Hab. Islands of Zebu and Ticao, Philippines (found on 



the reefs and under stones at low water) ; Cuming. 



I quite agree with Mr. Gray in referring this shell to 



the Voluta scabricula of Linnseus. 



Species 36. (Mus. Cuming.) 



Mitra Chinensis. Mitr. fusiformi, spird turritd, api- 

 cem versus plerumque erosd ; anfractibus subrotun- 

 datis, obsolete punctato-striatis, anfractu ultimo prope 

 basim subobscure sulcatis, basi leviler recurvo ; colu- 

 melld triplicatd. 



The Chinese Mitke. Shell fusiform, spire turreted, 

 generally eroded towards the apex ; whorls some- 

 what rounded, obsolete]}' striated with punctures, 

 last whorl rather obscurely grooved towards the 

 base, base slightly recurved ; columella three- 

 plaited. 



Gray, Zoology of Beechey's Voyage, pi. 35. f. 2. 



Hab. China. 



This species presents the same fluviatile character as 

 the Mitra nigra ; it is however a much more solid shell, 

 and of a more turriculated fusiform shape. 



Species 37. (Mus. Cuming.) 



Mitra sph.erulata. Mitr. testd elongato-ovatd, apice 

 pailide rosaceo, anfractibus transversim rugoso-cos- 

 tatis, costis subnodulosis, sulcis lineisve impressis con- 

 fertis longitudinalibus decussatis; aurantio-lutescente, 

 costis ceerulescente-albis, caruleo-niyricante irregula- 

 riter maculatis ; columelld quadriplicatd, apertures 

 fauce aurantio-lutescente ; labro crenuluto. 

 The spherical Mitre. Shell elongately ovate, apex 

 rose-tinted ; whorls transversely roughly ribbed, 

 ribs somewhat nodulous, decussated with close-set 

 longitudinal grooves or impressed lines ; orange- 

 yellow, ribs blueish white, irregularly spotted with 

 blue-black ; columella four-plaited ; interior of the 

 aperture orange-yellow ; lip cr°nulated. 

 Martyn, Universal Conch., f. 21. 

 Mitra scabriuscula, Lamarck. 

 Hab. Islands of Ticao, Philippines, and Taheite, Pacific 

 Ocean (found buried in sand at low water) ; Cu- 

 ming. 



The shell which Lamarck described under the name 

 of Mitra granatina (Sp. 35), and not this species, is the 

 Voluta scabriuscula of Linnreus. Kiener says they ought 

 to be regarded as varieties ; he has been fortunate, how- 

 ever, not to figure them as such, for no extended series 

 of examples could ever bring them to an approximation.
