Inhabits the Indian Ocean. Linnccus. Coasts of Amboyna. 

 Rumphius. Moluccas. Favanne. 



The length varies from two to four inches, and the diameter 

 from three to five lines ; the colour is brown or yellowish, 

 becoming darker towards the summit, and nearly white in the 

 inside ; the tube is more or less curved throughout its whole 

 length, and terminates at one end in a rather compact pointed 

 coil, or spire, of from six to ten whirls. Linnaeus describes 

 the spiral end to be the summit of the shell, of which the 

 correctness is rather doubtful, and it appears far more likely 

 that the spiral end is the part by which it adheres to the rock 

 or other substance to which it is naturally attached ; if this 

 is the case, Le Vermet of Adanson, t. 11. f. 1, Martini, 

 t. 3. f. 24 B, and Favanne, t. 6. f. H, and t. 68. f. G, may 

 probably belong to this species, but not as the Linnaean cha- 

 racter now stands, * apice spirali acuto.'

 ral at the base.

Inhabits the coasts of America, adhering to rocks. Favatme. 

 Amboyna. Rumphius. 



Tube rather thick, brownish white, and coiled into a conical 

 spire of about eight whirls at the base ; the summit rises 

 about nine inches from the rock to which the shell adheres, 

 but the length is probably thrice as great, owing to the coils 

 at the base ; and the diameter of the tube is about two lines 

 and a half. 



ARENARIA. 24. Shell jointed, entire, distinct, and 

 ratlier flat beneath.
