The flowery Strombus. Shell oblong-ovate, thick- 

 ened, sharply grooved at the base, spire generaUy 

 rather sharp, sometimes exserted, whorls spii-ally 

 finely ridged and lineated, margined next the sutures, 

 then obtusely angled, obliquely tubercled at the 

 angle, tubercles sometimes fading away, colmnella 

 laminately thickened, finely wrinkled throughout, 

 aperture oblong, interior finely wrinkled, lip tliick- 

 ened, slightly dilated at the upper part, as if to form 

 a tubercle ; whitish, sometimes yellow-stained, va- 

 riously blotched or streaked with orange-brown or 

 purple-black, interior of the aperture delicate scarlet- 

 pink.

Hnh. Island of Ticao and Bohol, Philippines, and Society 

 Islands (on the reefs) ; Cuming. 



This species, as 5Ir. Swainsou's name for it indicates, is 

 very changeable both in form and colouring. Its charac- 

 ters of sculptm-e are constant. The spire is mostly rather 

 short, but sometimes it is elongated as in the specimen re- 

 presented at Fig. \\c,d. The more acuminated the spire 

 is in this genus, the more noduled it is. This pecidiarity is 

 well illustrated in the specimens of S. floridus represented 



in the accompanying plate, and we have a remarkable 

 instance of the attenuated nodulous spire in S. T/icnlfrs of 

 the preceding plate. In S.Jloridus the columellar lamina 

 is unusually thickened, and the outer lip is callously dilated 

 where it joins this on the body-whorl, as if to form a tu- 

 bercle. 



Species 13. (Mus. Brit.)

The hawk-wini; Stuo:\ibus. Shell somewhat sipiarely 

 ovate, stout, thick, ponderous, abruptly recm'ved at 

 the base, spire short, shai-j), spirally many-ridged, 

 obscurely nodose, whorls radiately rather obscurely 

 ribbed, depressly concave round the upper part, no- 

 dosely tubercled at the angle, dorsal tubercles of the 

 last whorl very large, columella callous, lip angidarly 

 dilated, often very much thickened; fawn-white, 

 sometimes faintly red-banded, covered with a thin 

 brown epidermis, columella aud interior of the aper- 

 ture reddish or white.

 Eadem var. Strombus iiiermis, Swainson. 

 Strombus costal us, Gmelin (not of Da Costa). 



Hab. West Indies. 



Distinguished by its compact massive form and noduled 



spire, which, though short, is always sharply acuminated. 



The specimen here figured from the British Museum is 



tinged with red, but the species is mostly white, sometimes 



acquiring with age a dark metallic hue.
