Hah. Island of Burias, Philippines (found in coral sand 

 at the depth of seven fathoms) ; Cuming. 

 This magnificent species, which I had the pleasure of 

 describing about three years since, constituted the chief 

 ornament of an important collection of Mitres accumu- 

 lated after many years' labour and expensive zeal by the 

 Rev. Mr. Stainforth. This collection has however been 

 recently augmented to a most valuable extent by the 

 liberality of Thomas Norris, Esq., who having purchased 

 it in addition to his own, is now in possession of about 

 a thousand specimens of Mitres, among which, as this 

 monograph of the genus will testify, are many of the 

 utmost rarity and beauty. 



A few small but richly coloured specimens of the 

 Mitra Stain/orthii were collected by Mr. Cuming at the 

 above-mentioned locality.

Mitra Dennisoni. Milr. testd fusiformi, spird atte- 

 nuato-acuminatd, anfractibus subconcentrici costatis, 

 transversim sulcatis, sulci* angustis, costas super 

 plus minusve obsolctis ; rubido-aurantid, zond unicd 

 albidd cingulatd, ceerulescente-olivaceo inter castas 

 peculiariter tinctd ; columella quadriplicatd. 



Dennison's Mitre. Shell fusiform, spire attenuately 

 acuminated, whorls somewhat concentricallyribbed, 

 transversely grooved, grooves narrow, more or less 

 obsolete upon the ribs ; reddish orange, encircled 

 with a single white zone, peculiarly stained with 

 blueish olive between the ribs ; columella four- 

 plaited.

Hab. Puteao, province of Albay, island of Luzon, Philip- 

 pines (found on mud-banks at low water); Cuming. 

 I dedicate this fine species with much pleasure, at the 



particular request of Mr. Cuming, to J. Dennison, Esq., 

 a gentleman who has acquired considerable fame in the 

 conchological world on account of the very choice and 

 select character of his collection of shells. 



Species 15. (Mus. Norris.) 

 Mitra stigmataria. Mite, testd fusiformi, spird acuta- 

 acuminatd; anfractibus transversim impresso-striatis,

 maculis rufis parvis uniseriatim vivide pictis, maculis 

 inter dum, sed raro, nullis ,• columella basique nigri-

 A delicately marked species, varying in colour from 

 pale yellowish white to dark ashy blue, generally encir- 

 cled with two rows of small bright red spots, the lower 

 row of which is only visible on the last whorl.
