THE COOK'S OR HARVEY ISLANDS. 403 



Like the preceding species this lives just above high-water mark, and, except- 

 ing the Gambier's, has the same extensive geographical range. 



The animal is pale grayish with dusky tentacles. The foot is the same as in 

 luteus. 



They vary more or less in the convexity of the last whorl, and the small plicae 

 on the spire is either very conspicuous or faint, and is sometimes confined to the 

 whorls near the apex. The base is occasionally obliquely striate as in Philippii. 



It is subject to considerable variation in color and fasciation. The ground 

 color in the type varies from pale bluish-white to luteous, and the bands range 

 from four to six. 



The following varieties occur: — 



a. Uniform bluish-white, corneous, luteous, and brownish or yellowish-brown.' 



b. Yellowish-brown with three chestnut-brown bands. 



c. Yellowish-brown with chestnut-brown base and spire. 



d. Olive-gray with three bluish-white bands. 



Variety b and c, which are larger and more robust than the type, only occurred 

 to my notice in the Samoa, Tonga, and Viti Islands. 



Prof. Mousson's Philippii, not of Kuster, I do not hesitate to refer to fasciata. 

 I collected many thousands of Melampi in various parts of Samoa, Tonga, and Viti 

 Islands, but did not find one of Kuster's species, which appears to be confined to 

 Southeast Polynesia.

This species, of which a single example was found at Karotonga, ranges from 

 the Paumotus to the Viti Islands. Tvxr. Pease records it from " Central Pacific." 

 It is rarely found alive. 



It is smaller and not so robust as L. Bronni of the Sandwich Islands. The 

 spiral impressed lines are more conspicuous, and the aperture exhibits a heavier 

 deposit of callus in the palate.
