Hah. Isle of Rietea, Society Islands (found on the reefs at 

 low water) ; Cuming. 



Well characterized by the narrow white zone which is 

 broader on the ribs than in the interstices. For another 

 variety of this species, see PI. XXVI. f. -202. 



Species L86. (Mus. Cuming.)

 tusd ; transversim fortiter sulcata, sulcis pertusis ; rubi- 

 ilii, liris transversis profuse albimaculatis ; columella

 The foreign Mitre. Shell oblong-ovate, spire rather ob- 

 tuse; transversely strongly grooved, grooves pricked ; 

 dark red, transverse ridges profusely --potted with 

 white.

liab. Island of Masbate, Philippines (found under stones 

 at low water) ; ( luming. 

 This species, which appears to be figured by Kiener for 

 the Mitra nucleola, may be connected by a series of inter- 

 mediate varieties with the Mitra cucumerina. 



Species 187. (Mus. Cuming.) 

 Mitra porcata. Mitr. testd ovatd, spin! breviusculd, 

 transversim wndique sulcata; ferrugineo-fuscd, alio hie

 The ridged Mitre. Shell ovate, spire rather short, trans- 

 versely grooved throughout ; rusty brown, irregular!} 



spotted here and there with white, interior brown; co-

A dingy shell of very obscure character, though suffici- 

 ently distinct from any hitherto described.

The laced Mitre. Shell oblong-ovate, truncated at the 

 base; whorls smooth, ashy brown, encircled with a 

 white band beneath the sutures and with close brown 

 parallel lilies over till; columella four-plaited; lip some- 

 what effused.

The honeycombed Mitre. Shell cylindrically ovate, 

 thick, solid, spire very short ; longitudinally ribbed, ribs 

 obtuse, rude, almosf obsolete, crossed with sharp re-

 Hah. Island of Ticao, Philippines (found on the reefs); 

 Cuming. 

 A well known species, but one of great rarity in fine con- 

 dition.
