 to that of the Mitra luruatu.

The friendly Mitre. Shell ovate, rather thick, spire 

 obtusely depressed ; whorls somewhat rounded, lon- 

 gitudinally ribbed, transversely impressly grooved;

Hab. Islands of Ticao and Capul, Philippines (found un-

An extremely pretty species, alternately banded with 

 white and ashy grey. 



Species 275. (Mus. Cuming.) 



Mitba PURPURATA. Mitr. testa ovatd, ntrinque altenuutn. 

 spird breviusculd, subturritd; anfractibus ad suturas 

 plano-angulatis, longitudinaliter cuxtatix, costis nume-

 cc/latix ; f/txeu-purpured, zona angustd alba cingulatd . 

 columella quadriplieatd. 



The purple-tinged Mitre. Shell ovate, attenuated at

 whorls flatly angulated at the sutures, longitudinally 

 ribbed, ribs numerous, narrow, prominent, interstices

 low water); Cuming. 



The whorls of this shell being flatly angulated at the 

 sutures give a turreted character to the spire.
