MITRA.— Plate XL 



round snow-white spots ; columella four-plaited ; 



aperture rather narrow, ashy violet within. 

 Kiener, Iconographie Coq. viv., p. 9. pi. 2. f. 5 

 Hob. Red Sea (found on the reefs at low water) ; Riip- 



pell. 

 I must congratulate M. Kiener upon having intro- 

 duced this extremely interesting coronated species, which, 

 though not uncommon in our collections, had not pre- 

 viously been either described or figured. 



Species 79. (Mus. Cuming.) 

 Mitra subulata. Mitr. testd acuminato-elongatd, Tcre- 

 braformi ; anfractibus longitudinaliter crebrisulcatis, 

 sulcis profundi impressis, Uriels impressis spiralibus 

 decussatis, ad decussationem puncturatis, lined superd 

 infra suturam sctp< profundiore; earned, rufo-au- 

 rantio nebulosd ; aperturd brevi, angnstd ; columella 

 quadriplicatd. 

 The BonKiN-snAPED Mitre. Shell acuminately elon- 

 gated, Terebra-shaped ; whorls longitudinally closely 

 grooved, grooves deeply impressed, crossed with 

 impressed spiral lines, punctured at the point of 

 crossing, uppermost line beneath the suture often 

 deeply impressed ; flesh-colour, clouded with reddish 

 orange ; aperture short, narrow ; columella four- 

 plaited. 

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

 Voluta ignea, Wood. 

 Tiara terebralis, Swainson (Broderip). 

 Mitra rosea, Duclos. 

 Hub. Island of Annaa (found on the reefs) ; Cuming. 



This species has very much the appearance of a Tere- 

 bra, and as Mr. Broderip remarks, the resemblance is 

 strengthened by the circumstance of there being one 

 spiral line more deeply impressed than the others just 

 beneath the suture in each volution. 



For Species 80, see Mitra, Plate XX. 

 Fig. 80. (Mus. Cuming.) 

 Conus edentulus. An interesting species of Cone 

 allied to the Conus mitratus. This shell was handed 

 to me amongst Mr. Svvainson's Mitres, with that 

 gentleman's manuscript name of Conohelix edentula 

 attached to it. Upon describing it, however, the first 

 important feature that presented itself was the ab- 

 sence of any indication of plaits upon the columella. 

 It is unquestionably a Cone, and I trust to be able 

 to publish an account of it under the above title in 

 Conus, Plate XLVIII. 



Species 81. (Mus. Cuming.) 



Mitra filosa. Mitr. testa ovato-fusiformi, spird acu- 

 minata, subtilissime plano-vancellatd, liris fi/osis tjra- 

 niferis elevatis undique cingulatd; rosaceo-albicunte, 

 liris rubido-fuscis ; columella quadriplicatd. 



The thread- bound Mitre. Shell ovately fusiform, 

 spire acuminated, very finely flatly cancellated, en- 

 circled throughout with elevated, graniferous, thread- 

 like ridges ; pinkish white, ridges reddish brown . 

 columella four-plaited. 



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

 Voluta filosa , Born, Gmelin. 



Variety (3. (Fig. 81 b.) 



Testa obesior, minus acuminata. 



Shell stouter, less acuminated. 



Mitra nexilis, Martyn, Lamarck. 



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

 Masbate, Philippines (found in coral sand on the 

 reefs and at the depth of six fathoms) ; Cuming. 

 I quite agree with M. Kiener in suppressing the Mitra 



nexilis ; Martyn figured the var. ft. under that name, not 



knowing probably the Vo/utafilosa, and Lamarck adopted 



Martyn's Mitra nexilis with an acknowledgement that 



he knew nothing of it.
