MITRA.— Plate III. 



Species 17. (Mus. Norris.) 



Mitra zonata. Mitr. testd ovato-fusiformi, Itevigatd, 

 spird subturritd ; anfractibus inferne nigerrimis, su- 

 pernt albidis, epidermide luted, fulvo-marmoratd in- 

 dutis ; columella quinqueplicatd. 



The zoned Mitre. Shell ovately fusiform, smooth, 

 spire somewhat turreted ; whorls very Mack round 

 the lower part, white round the upper, covered with 

 a yellow fulvous marbled epidermis ; columella five- 

 plaited.

 pi. 10. i. 1 and 2. 

 Mitra Santangeli, Maravigna. 



Hub. Mediterranean (taken up near the port of Nice, 

 adhering to a sounding lead in very deep water) ; 

 Marryatt. 



This remarkable species, an inhabitant of the Medi- 

 terranean, though discovered nearly thirty years since, 

 and successively described and figured by Swainson, 

 Risso and Kiener, is very rarely found. The example 

 here represented, from the collection of Thomas Norris, 

 Esq., is, I believe, the only one in this country. A worn 

 uncoated specimen has been described and figured by 

 M. Maravigna in the ' Magasin de Zoologie' under the 

 name of Mitra Santangeli. 



Species 18. (Mus. Norris.) 



Mitra solida. Mitr. testa ovato-elongatd, crassd, so- 

 lidd, spird subturritd ; anfractibus numerosis, con- 

 vexis, Itevigatis, transversim sulcatis, sulcis angustis, 

 s/riis subtilissimis prope suturas decussatis; spadiceo- 

 fulvd.albo sparsim etirregulariter floccatd; columelld 

 quinqueplicatd. 



The solid Mitre. Shell ovately elongated, thick, 

 solid, spire somewhat turreted ; whorls numerous, 

 convex, smooth, transversely grooved, grooves nar- 

 row, crossed near the sutures with very fine longi- 

 tudinal striae ; fulvous bay-colour, irregularly flaked 

 here and there with white ; columella five-plaited. 



Reeve, Pro. Zool. Soc, 1844. 



Hub. ? 



This interesting species may be recognised by its many 

 convex, deep-sutured whorls ; and the whorls being lon- 

 gitudinally striated uear the sutures, exhibit a sb>ht 

 cancellated appearance. 



Species 19. (Mus. Norris.) 



Mitra puncticulata. Mitr. testd oblongo-ovatd, spird 

 breviusculd, suturis profundis ; anfractibus superne 

 mucronato-coronatis, transversim sulcatis, sulcis im- 

 pressis, puncticulatis ; rufescente-aurantid, flammis 

 fuseislongitudinalibus sparsim pictd; anfractu ultimo 

 zona latiusculd htescente albifloccatd cingulato ; co- 

 lumelld quadriplicatd. 



The punctured Mitre. Shell oblong-ovate, spire 

 rather short, sutures deep; whorls sharp-pointedly 



coronated at the upper part, transversely grooved, 

 grooves impressed, punctured ; reddish orange, 

 painted here and there with brown flames ; last 

 whorl encircled with a rather broad white-flaked 

 pale yellow zone ; columella four-plaited.

 Mitra diadema, Swainson. 



Hab. Philippine Islands (found under coral on the reefs 

 at low water) ; Cuming. 



This well-known species was found abundantly by 

 Mr. Cuming at the above-mentioned locality. 



Species 20. (Mus. Norris.) 



Mitra caffra. Mitr. testd fusiformi, spird transversim 

 striatd, longitudinaliter plicatd, anfractu ultimo lavi, 

 basim versus elevato-striato ; rufescente-fuscd, zond 

 luted angustd unicd cingulatd, anfractu ultimo zonis 

 duabus ; columella quadriplicatd. 



The negro Mitre. Shell fusiform, spire transversely 

 striated, longitudinally plaited, last whorl smooth, 

 elevately striated towards the base ; very dark red- 

 dish brown, encircled with a single narrow yellow 

 zone, last whorl with two zones ; columella four- 

 plaited.

 Valuta caffra, Linnaeus. 

 Mitra bifasciata, Swainson. 



Hab. Island of Ticao, Philippines (found under stones 

 and on mud-banks at low water, and in sandy mud 

 at the depth of six fathoms) ; Cuming. 

 The sculpture of this species is somewhat variable, 



inasmuch as the upper whorls are much more strongly 



plicately ribbed in some specimens than in others. 



Species 21. (Mus. Norris.) 

 Mitra digitalis. Mitr. testd oblongo-ovatd, in medio 

 subattenuatd, spird breviusculd ; anfractibus tuber- 

 ru/is parvis obtusis coronatis, transversim sulcatis, 



sulcis angustis, iinpresso-punetatis, subdistantibus ; 

 luted, lutesrente-fusco rarid, macu/is gruntlibus albis 

 irrcgularibus seriatim einetd ; columelld se.rplicutd. 



The thimble Mitre. Shell oblong-ovate, somewhat 

 attenuated towards the middle, spire rather short ; 

 whorls coronated with small blunt tubercles, trans- 

 versely grooved, grooves narrow, impressly punc- 

 tured, rather distant ; yellow, variegated with yel- 

 lowish brown, encircled with large irregular white 

 spots ; columella six-plaited.

Hull. Island of Ticao, Philippines (found in sandy mud 

 at the depth of six fathoms) ; Cuming. 



A well-known species, of a very peculiar style of co- 

 louring. La Thiare a Cul de l)c of Favanne.
