THE GOLDEN TrocHus. Shell superficially umbilicated, 
obtusely depressly conoid, sometimes golden-fulvous,

' THE scaty Trocnus. Shell imperforate, obtusely de- 
pressly conoid, brownish-white; whorls convex, ob-

Trochus fimbriatus, var., Philippi. 
Hab. ——? 
This appears to me to be constantly distinguished from 
T. fimbriatus, in the manner shown by our respective 
figures of the two species. 
Species 61. (Mus. Cuming.) 
TrocHUs HEXAGONUS. Troch. testa imperforatd, subobtuse 
conicd, albidd, aureo-ferrugineo tinctd; anfractibus

tis, deinde obtusé tuberculatis ; basi planiusculd, dense 
irregulariter sguamatda. 
THE HEXAGONAL Trocuts. Shell imperforate, rather ob- 
tusely conical, white, tinged with golden-rust ; whorls 
concavely sloping, rudely plicately wrinkled and mal-

Puitiper, in Kiister, Conch. Cab. p. 130. pl. 22. f. 9. 
Hab. Australia. 
With somewhat of the form of 7. rhodostoma, but the 
sculpture is of a ruder and more obtuse character, and 
there is no indication of colour about the basal callesity. 
Species 62. (Mus. Cuming.) 
Trocuus acuLgatus. Troch. testd imperforatd, conicd, 
aurantio-spadiced ; anfractibus declivi-convevis, oblique

margine basali muricato-squamato ; bast circa callosi- 
tate squamato-liratda.
