Tiara miUecostata, Swainson (Broderip), Pro. Zool. 

 Soc, 1835. 

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

 in shallow water) ; Cuming. 

 This shell, as Mr. Broderip observes, has very much the 

 aspect of a young Cancellaria.

Hab. ? 



I have found no specimen approaching comparison with 

 that here represented from the collection of Thos. Norris,

 iiter obtuso-costatd, costarum interstitiis transversim 

 cancel! at is ; eburned, anfractu ultimo fascia lata oliva- 

 eeo-oinered,fusco indistincte punctata, cingulatd; colu-

The pleasant Mitre. Shell pyramidally ovate, longi- 

 tudinally obtusely ribbed, interstices between the ribs 

 transversely cancellated ; ivory-white, last whorl en- 

 circled with a broad olive-ash belt, indistinctly dotted 

 with white ; columella four-plaited. 



Reeve, Pro. Zool. Soc, 1845. 



Hab. Puerto Galero, Island of Mindoro, Philippines (found 

 on the sands) ; Cuming. 

 A very solid ivory white shell, encircled with a dark 



band which is concealed in the upper whorls by the super- 



position of one whorl upon the other in the ordinary course 

 of growth. 



Species 304. (Mus. Cuming.) 



Mitra pinguis. Mitr. testa subobeso-ovatd, longitudina- 

 liter suboblique noduloso-costatd, transversim impresso- 

 strialii. striis creberrintis, aiifractus vltimi parte infe- 

 riori sulcata; albidd, fascia unicd fuscescente cingu- 

 latd; columella quadriplicatd. 



The plump Mitre. Shell rather stoutly ovate, longitu- 

 dinally somewhat obliquely nodulously ribbed, trans- 

 versely impressly striated, striae very close-set, lower 

 portion of the last whorl grooved ; whitish, encircled 

 with a single pale brown baud ; columella four-plaited.

Hab. Puerto Galero, Island of Mindoro, Philippines ; 

 Cuming. 



The last whorl of this shell exhibits a peculiarity of 

 structure which is worthy of observation ; above the brown 

 band it is very closely impressly striated across, below it, 

 it is merely distantly grooved. A difference between the 

 transverse sculpture of the upper and lower portions of the 

 whorls is rarely met with. 



Species 373. (Mus. Cuming.) 



Mitra peculiaris. Mitr. testa elongatd, anfractibus lari- 

 bus, concavis, carina unicd prominente superne ornatis ; 

 albidd, fascia lata luteo-fuscescente cingulatd ; columella 

 biplicatd. 



The peculiar Mitre. Shell elongated, whorls smooth, 

 concave, ornamented with a single prominent keel 

 round the upper part ; whitish, encircled with a broad 

 yellowish-brown band, columella two-plaited. 



Reeve, Pro. Zool. Soc, 1845. 



Hab. Puerto Galero, Island of Mindoro, Philippines (found 

 under stones at low water) ; Cuming. 



This species may be easily distinguished by the hollow 

 character which is imparted to the whorls by the very pro- 

 minent keel round the upper part.
