Hab. Pasacao, Island of Luzon, Philippines (found on the 

 sands); Cuming. 

 The form and colour of this species reminds one some- 

 what of certain varieties of the Mitra eberms, from which it 

 is, however, perfectly distinct.

The form of the Mitra ccgra is very similar to that of 

 the Mitra cylindracea ; but, as may be seen by the descrip- 

 tions, they differ materially in sculpture. 



Species 253. (Mus. Cuming.) 

 Mitra muricata. Mitr. testa ova Id, spird brevi ; longi- 

 tudinaliter noduloso-costatd, transversim lineato-im- 

 pressd ; fiiacd, epidermide olirared iudidd ; columella 

 triplicatd. 

 The muricated Mitre. Shell ovate, spire short, longi- 

 tudinally nodulously ribbed, transversely lincately 

 impressed ; brown, covered with an olive epidermis ; 

 columella three-plaited. 

 Swainson (Broderip), Pro. Zool. Soc, 1835. 



Hah. Gallapagos Islands (dredged from sandy mud at the 

 depth of six fathoms) ; Cuming. 

 This species may be recognised by its high-shouldered 

 form, and the rough nodulous character of its sculpture. 



Species 254. (Mus. Cuming.) 



Mitra modesta. Mitr. testa subfusifonni-ovatd, basi con- 

 tractu, spird turritd ; anfractibus rotundutis, Inmjitu- 

 diiiuliter costatis, interstitiis traiixcersim cancellato- 

 impressis ; nieed, rosaceo basem versus pallidissime 

 tinctd; columella quadriplkatd, apertwa fauce rosacea. 



The modest Mitre. Shell somewhat fusiformly ovate, 

 contracted at the base, spire turreted ; whorls rounded, 

 longitudinally ribbed, interstices transversely cancel- 

 lately impressed; snowy white, very paleh stained 

 towards the base with pink ; columella four-plaited ; 

 interior of the aperture pink.

Hab. Island of Ticao, Philippines (found on the reefs at 

 low water) ; Cuming. 

 A very chaste pink-white shell with a highly relieved 



latticed sculpture. 



Species 255. (Mus. Cuming.) 

 Mitra fulvescens. Mitr. testa abbreviato-fusiformi, 

 crassd, spine siituris subprofundis ; laevigata, tramver- 

 sim undique punctato-striatd ; luteo-ftdvescente ; co «■

 The pale-brown Mitre. Shell shortly fusiform, thick, 



sutures of the spire rather deep, transversely striated 



with punctures throughout ; pale yellowish brown ; 



columella five-plaited. 

 Swainson (Broderip), Pro. Zool. Soc, 1835. 



Mitra striata? Gray; Zool. of Beechey's Voyagi 

 Hab. Island of Annaa, Pacific Ocean (found on the reefs); 



Cuming. 

 The general character of this shell so closely resembles 

 that of the Mitra fulva that it might be taken for the 

 young of that species, were it not for the difference of its 

 proportions.
