TURBO. 205 



viride, minutissime granulatum. — A very variable species. 

 The smooth marbled form (fig. 45) represents T. porphyrites\ 

 the ribbed form, with greea articulated spots ^fig. 40;, 

 T. versicolor; fig. 42 represents a ribbed shell of a plain 

 reddish-brown colour. Another specimen I have before me 

 is scarcely ribbed, but spirally striated, of a reddish-brown 

 colour, with a conspicuous yellowish central zone. — Hab. 

 Philippines, Australia, &c.

 Testa globosa, interdum perforata, plerumque albida, viridl 

 et fusco tincta, interdum rufo-fusca ; spira plus minusve 

 depressa ; anfractus circ. 5, superne levissime declives, spi- 

 raliter nodulosi, plus minusve corrugati, nodulis vel squamis 

 elevatis ad sutura coronati ; anfractus ultimus plerumque 

 biseriatim squamatus, inferne productus ; apertura circularis, 

 vel subquadrata ; columella lata impressa. Operculum extus 

 valde convexum, granulatum, lividum. — A very variable 

 species, illustrating the futility of depending on any one 

 character for the establishment of a species. Fig. 51 repre- 

 sents the typical form, 52 Hempritchi, 53 lugubris, 54 creni- 

 ferus. Some specimens are deeply and openly umbilicated, 

 others slightly so, and others again have not the slightest 

 indication thereof. Having examined a large number of 

 specimens of different sizes, forms, and stages of growth, I 

 am compelled to treat them as one species. — Hab. Indian 

 Ocean, Red Sea, China Sea, &c.
