 columella octoplicatd, itttits alba. 

 The crenulated Mitre. Shell cylmdrically ovate, rather 

 thick, spire very short, edge of the whorls erenulated ;

Voluta crenulata, ( Ihemnitz. 

 Hoi. Island of Ticao, Philippines (found under stones at 

 low water) ; Cuming. 

 The entire surface of this species is simply decussated 

 with impressed lines, and the painting is clouded in a cha- 

 racteristic waved manner from the erenulated summit of 

 the whorls to the base.

 libus impressis exilibus decussatd ; fused; coin, eel hi ,/,--

 The Chinese Mitre. Shell cylindrically oblong, thick, 

 spire very short, sharp; transversely closely ridged, 

 ridges narrow, prominent, granose, decussated with

This fine species, though one of great rarity, has been 

 probably confounded hitherto with the Mitra crenulata, an 

 error into which 1 had myself fallen, as the irregularity of 

 the figures of reference show, until the arrival of a magni- 

 ficent specimen most liberally forwarded to me for inspec- 

 tion by Mr. Cmmer of Bremen. The accompam ing figure 

 being already engraved from a smaller specimen in the col- 

 lection of Lady Finch, for the drawing of which I am m- 

 debtedto the kindness of Mr. Sowerby, Mr. Grriiner's shell 

 lias not served me for illustration; for description it has been 

 invaluable as the means of establishing a new and very im- 

 portant species. It differs entirely from the Mitra crenu- 

 lata, independent of colouring and size, in the character of 

 its sculpture, whilst the columella has an additional num- 

 ber of plaits, and is armed with a remarkable callosity at 

 I In- summit. 



Species 192. (Fig. 191, Mus. Cuming.) 



MlTRA glans. Mitr. testa ovatu, siilic;/liml raced, siipenie 

 obesd, crassd, solidd, spird brevissimd, partim occulta; 

 longitudinaliter obtuso-costellatd, costettis fortiter gra- 

 nulosis ; rirnlr aurantio-fuscd, granulis albidis, intm 

 alba ; columella octoplicatd. 



The acorx Mitre. Shell ovate, somewhat cylindrical, 

 stout round the upper part, thick, solid, spire very 

 short, partially hidden, longitudinally obtusely ribbed, 

 ribs strongly granulated; bright orange brown, gra- 

 nules whitish, interior white ; columella eight-plaited. 



Peeve, Pro. Zool. Soc., 18 14. 



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

 low water) ; Cuming. 

 Characterized by its very distinctly granulated sculpture, 



and by its short obese form. 



Species 193. (Fig. 192, Mus. Norris.) 

 Mitra undulosa. Mitr. testa cylindraceo-ovatd, crassd, 

 spird brevissimd; Iteviusculd, lineis exiliter impressis 

 a, nil que cinctd; all"', lineis fuscis cingulatd, umdulisqw 

 fuscis angustis longitudinalibus variegatd; columella 

 octoplicatd. 

 The pestooxed Mitre. Shell cylindrically ovate, thick. 

 spire very short ; rather smooth, encircled throughout 

 with faintly impressed line- ; while, encircled with fine 

 brown lines, and variegated with narrow brown longi- 

 tudinal waves ; columella eight-plaited. 

 Reeve, Pro. Zool. Soc., 1844. 



Hab. Island of Ticao, Philippines, (found among coral sand 

 on the reefs at low water) ; Cuming. 

 The lmeatcd character of the painting is so different hi >m 

 that of the M. crenulata, that I cannot refrain from sepa- 

 rating it as a distinct species. 



Specie- 194. (Fig. L93, Mus. Cuming.) 

 Mitra nanus. Mitr. testa abbreviato-ovatd, spird brevi, 

 acuta, transversim undique sulcata, sulci* basem sem - 

 profundioribm ; rubido-fuscd, balteo angustofumicante, 

 peculiariter albimaeulatd, cinctd; columella quadri- 

 p/icafd. 

 THE dwarf MITRE. Shell shortly ovate, spire short. 

 sharp, transversely grooved throughout, grooves deepei 

 towards the base; reddish brown, encircled witli a 

 narrow peculiarly white-spotted yellow belt ; columella 

 four-plaited.

Distinguished by its narrow yellow belt which has B pe- 

 culiar white knotted appearance.
