608 BUCCINUM. 



ter. Amboyna. Rumphim. Coromandel. Martini. Chi- 

 na. Humphreys. 

 Shell most commonly from two to three inches long, and near- 

 ly two thirds as broad, variously marbled, undulated, and 

 banded with fawn-colour, reddish brown, rose-colour, and 

 white, and marked with large irregular brown spots on the 

 pillar. All its numerous varieties in size and colour approach 

 each other by so many almost imperceptible gradations, that 

 it is difficult to find any specific marks to distinguish them. 



CANCELLATUM. 49. Shell with longitudinal, mu- 

 cronate ribs, and their interstices transverse- 

 ly striated; pillar smooth. 



Harpa cancellata. Chemnitz, x. t. 152. f. 1453. Hum- 

 phreys in Callone's Cat. p. 18. No. 293. 

 Buccinum Harpa, Var. Gmelin, p. 3482. Bruguiere 

 Enc. Meth. p. 450. 



Inhabits the coasts of Tranquebar. Chemnitz. 



Shell about an inch and a half long, and near two thirds as 

 broad, with fifteen or sixteen longitudinal ribs, and it differs 

 principally from B. Harpa in having the spaces between the 

 ribs transversely striated. Mr. Humphreys suspects it may 

 be the young of Solander's B. Testudo. 



cosTATUM. 50. Shell -with crowded lonsitudinal 



mucronate ribs; pillar smooth.

 Inhabits the Philippine Islands. Humphreys. 

 This shell is still more nearly allied to B. Harpa than the pre- 

 ceding, and in a specimen now before me the ribs on the 

 side next the pillar-lip are much crowded, whilst those on 

 the other half of the shell become abruptly twice as remote, 

 and Linnaeus has therefore probably erred in arranging it as 

 a separate species. 



PERSicuM. 51. Shell scabrous, with a crenulated 

 outer lip and flat pillar.
