 Tub Robin-red-breast Triton. Shell ovately oblong, 

 thick, with six prominent varices ; spire obtuse ; 

 whorls transversely granulously ridged, sometimes, 

 but rarely, armed at the back with a single blunt 

 tubercle, ridges divided into two over the varices, 

 interstices between the ridges decussately striated ; 

 bright orange-red, ornamented round the lower 

 part with a narrow orange belt, varices spotted 

 with white ; columella red, crossed with white 

 wrinkles, interior of the aperture white ; lip solid, 

 thickened, margin-toothed within. 



Variety ft. (Fig. b and c.) 

 Testa anfractibus medio lutcscentibus, supra et infra 



fuscis. 

 Shell with the whorls pale yellow in the middle, and 

 brown above and below.

low water) ; Cuming. 

 The three beautiful varieties of this species above 

 enumerated are very distinctly figured by Martini 

 (Conch., vol. iv. pi. 132. f. 1259 to 12G7). The first va- 

 riety (a) is of an uniform bright orange-red, with the 

 varices ornamented with large blotches of pure white ; 



the second variety (ft) is belted with lemon-coloi 



brown; and the third variety ( y ) is of bright orange 

 with all the interstices between the ridge.- blackish 

 brown, excepting that one which corresponds with the 

 orange belt in variety a.

The lamp Triton. Shell ovately conical, ventricose 

 at the lower part, with ten or more holed varices ; 

 spire acuminately turreted ; whorls somewhat an- 

 gulated at the upper part, transversely ridged and 

 ribbed, ribs and ridges knobbed in a rather irre- 

 gular crisped manner, strongly tuberculated, tuber- 

 cles compressed, arranged in two rows ; whitish 

 or cream-colour, stained and variegated with pale 

 orange-brown ; columella very finely wrinkled ; 

 canal very short, twisted ; lip denticulated, strongly 

 channeled at the upper part ; columella and in- 

 terior of the aperture fleshy orange, sometimes

Murex lampas, Linnaeus. 

 Lampas hyans, Schumacher. 



Hub. Philippine Islands (found on the reefs) ; Cuming. 

 This species, which is exceedingly variable in size, is 



remarkable for the channeled structure of the lip at its 



junction with the columella after the manner of that of 



the Ranella bufonia.
