38 GARRETT: ON POLYNESIAN MITRID^E. 



The spiral ridge on the angulate shoulder is a little 

 larger than the others and forms a row of larger granules, but 

 not pointed as stated by Reeve. The spiral row of foveae 

 immediately above the angle is also twice the size of the 

 others, forming shallow square pits with two contiguous 

 ridges next to the suture. 



86. Turricuia bilineata Reeve, 1. c, pi. xxxv., fig. 294. 



A very rare species of which we obtained two dead 

 specimens on the fringing reefs at Kioa, Viti Islands. 



Mr. Reeve's figure and description accords so nearly 

 with our shells that I do not hesitate to consider them the 

 same, though having one columellar plait less than mentioned 

 in his description. His figure shows four plaits the same as 

 our shells. The two spiral lines on a polished blackish- 

 brown ground will readily distinguish the species. 



87. Turricuia bella Pease. Proc. Zool. Soc, i860, p. 145. 



This somewhat scarce species appears to be peculiar to 

 the Sandwich Islands, where they live on sandy bottoms in 

 the upper region of the laminarian zone. 



88. Turricuia bicolor sp. nov. 



Shell small, fusiform, slightly shining, cinereous, with 

 two transverse rose colored bands on the body whorl, the 

 upper one traversing the whorls of the spire; spire with 

 slightly concave outlines; whorls embryonal 3, smooth, irregu- 

 larly increasing, normal whorls 6-7, nearly flat, somewhat 

 shouldered, the last one convex, depressed on the right side, 

 base strongly contracted, granulated and produced into a 

 short recurved canal; surface longitudinally ribbed, ribs 

 smooth, angular, 12-13 o^ the body whorl, interspaces with 

 fine transverse grooves; aperture narrow, little more than 

 half the length of the shell; peristome moderately thick and 

 distinctly sinuous above; columella with four plaits. 



Length 8 mill. (Mus. Godeffroy).
