nor closely-set, obsolete or nearly so on the last whorl; 

 interstices with distant transverse linear grooves, most 

 conspicuous on the upper whorls; aperture less than half the 

 length of the shell; columella with four plaits. 



Length 19 milU. (Mus. GodefTroy). 



Hab. Viti Islands. 



Appears to be rather scarce ; only several dead specimens 

 found on the sandy-mud flats at Kioa Island. It may easily 

 be distinguished by its peculiar color and constant white line. 

 The low distant ribs give the whorls a polygonal outline when 

 seen from above.

We were very fortunate in discovering five living examples 

 of this superb species, which were found on sandy-mud 

 bottoms in sheltered bays at Vanua Levu, Viti Islands. 



Reeve's poor and indifferently colored figures give but a 

 slight idea of the beauty of this scarce shell. 



Our examples, the largest of which is 2^ inches long, 

 are of a rich orange-yellow or orange-red, encircled with a 

 broad white zone, which sometimes carries a median narrow 

 brown line. The lower portion of the body whorl has a 

 second but smaller band of a pale yellow color. Both bands 

 are edged with dark brown fillets, and the upper one occupies 

 the lower half of each whorl of the spire. Aperture white, 

 more or less stained with orange. 



The upper portion of the body whorl is somewhat 

 angulate and slightly concave above the angle.

Mitra fraiercula Garr. Proc. Zool. Soc, 1872, p. 482. 

 This rare and pretty species, which is seldom found in 

 good condition, occurs under dead coral on the outer reefs 

 / and ranges from the Pafmotu to the Viti Islands.
