MITRA.— Plate XXII.

Hub. ? 



The sculpture of this attractive species approaches verj 

 nearly to that of the Mitra interlirata from which it differs 

 more materially in form. 



Species 171. (Mus. Metcalfe.) 



Mitra loricata. Mitr. testa fusifoitni, utrinque attenu- 

 atd, spires anfractUmsplano-convexis -.fortiter noduloso- 

 granosis, granis regularibus, seriatim creberrime diges- 

 tif : albidd, maeulis perpaucis aurantio-fuscescentibus 

 hie ittic fasciatim tinctd; columella quinqueplicatd. 



The mailed Mitre. Shell fusiform, attenuated at both 

 ends, whorls of the spire flatly convex; strongly no- 

 dulously granuled, granules regular, close-set in rows ; 

 whitish, stained here and there with a very few light 

 orange-brown spots in hands; columella five-plaited.

Hub. ? 



The entire surface of this species, from the collection 



of \V. Metcalfe, Esq., is very strongly closely granulated. 



Species 175. (Mi 



Mitra maculosa. Mitr. testa oblongo-ovatd, spird bre- 

 viusculd, suturis impressis ; anfracttftus transversim 

 punctato-striatis, parte superiori lutescente-albd fusces- 

 centepartim tinctd, infra castaneo-fuscd albipunctatd ; 

 columella quinqueplicatd; labro intus superne nnuato. 



The speckled Mitre. Shell oblong-ovate, spire rather 

 short, sutures impressed ; whorls transversely striated 

 and punctured, upper part yellowish while, partiaPj 

 stained with brown, beneath chesnut brown speckled 

 with white dots; columella five-plaited; lip sinuated 

 interiorly at the upper part. 



Peeve, Pro. Zool. Soc, 1844. 



Hub. Australia ; and Island of Annan, Pacific Ocean (found 

 at the latter place on the reefs); Cuming. 



This species may lie recognised by its peculiarity of co- 

 louring, the upper portion of the whorls being nearly white, 

 stained just lure and there with brown, the lower chesnut- 

 brown speckled with white dots. 



Species 176. (Mus. Taylor.) 



Mitra sulcata. Mitr. testa acuminato-ovald, spird bre- 

 oiusculd, acuta; anfractibus superne vix angulatis, 

 costis carinafonnibus elevatis subdistantibus undique 

 regulariter cinctis, sulcis inlerstitialibus concavis .■ fus- 

 cescente, epidi rmide nigricante-fuscd indutd; columella 

 quadriplicatd. 



The grooved Mitre. Shell acuminately ovale, spire ra- 

 ther short, sharp-pointed ; whorls very slightly angu- 

 lated at the upper part, encircled with particular re- 

 gularity throughout by rather distant elevated keel- 

 like ribs, interstitial grooves concave; light brown, 

 covered with a very dark brown epidermis.

Tiara sulcata, Swainson, Zool, Dlus., 2nd Series. 



Hid). Mouth of the river Chiriqui, Province of Veragua, 

 West Columbia (found in tine black sand al the depth 

 of four fathoms); Cuming. 

 Figured by M. M. Kiener and Kiister with ingenuous 



fidelity from Swainson's magnified representation in the 



' Zoological Illustrations.' 



Species 177. (Mus. Cuming.) 



Mitra proscissa. Mil/-, testa oblongo-ovatd, utringue 

 attenuatd, spiree anfractibus contiguis, suturis impres- 

 sis; transversim undique liratis, liris latiusculis, ob- 

 tuso-convexis, confertis, interstitiis angustis, subtilissinu 

 cancellatis ; albidd, maeulis aurantio-fuscescentibus bi- 

 fasciatim tinctd. 



The PLOUGHED Mitre. Shell oblong ovate, attenuated 

 at both ends ; whorls of the spire contiguous, sutures 

 impressed ; transversely ridged throughout, ridges 

 rather broad, obtusely convex, close-set, interstices 

 narrow, very finely cancellated; whitish, stained with 

 two bands of light orange-brown spots.

Hob. ? 



It may be as well to caution the reader against con- 

 founding this shell with the Mitra ferruginea (Sp. 28.), a 



name which I have seen erroneously attached to it in one 

 or two important collections.
