88 CHICOREUS. 



spine. M. Gambien&is, Reeve (fig. 521), from the mouth of the 

 Gambia, W. Coast of Africa, is evidently the same species, and I 

 suspect that M. uncinarius, Lam., from Cape of Good Hope, 

 will prove to be the young ; I find no other difference than size 

 between them. 



M. SPECIOSUS, A. Adams. PI. 41, fig. 532. 



Ovate fusiform, whorls seven, spire acute; varices three* 

 foliate, dilated into spines posteriorly ; surface with revolving 

 ribs and nodulous ; aperture oval, canal straight, closed. Whitish 

 tinged with red. Length, 3 inches. 



No dimensions or habitat given in the original description, but 

 said to be somewhat allied to M. alabaster. Mr. Sowerby 

 has recently figured the species, and assigns Yokohama, Japan, 

 as the habitat. 



M. UNCINARIUS, Lam. PI. 40, figs. 521, 523. 



Shell whitish or light brown. Length, "75 inches. 



Cape of Good Hope. 

 Probably the young of M. osseus. 



M. ANGASI, Crosse. PI. 40, fig. 522. 



Light 3^ellow, with a violet band. The body whorl appears to 

 be somewhat more swollen below than in M. uncinarius and the 

 spines are shorter and more direct than in that species. De- 

 scribed as a Typhis, and as having two internodes, but the figures 

 show only one large node. Length, '75 to 1 inch. 



Under rocks and stones low water. 



Port Jackson, Austr .; New Zealand ( Murex eos, Hutton). 

 M. QUINQUELOBATUS, Sowb. PL 41, fig. 528. 



Yellowish ; the varices developed into five hooked fronds, con- 

 nected by a narrow web-like lamina at their base. 



Length, 28 mill. 



Hab. unknown. 



Possibly only a form of M. uncinarius, Lam. 



Sub-genus Chicoreus, Monti. 



The species are mainly oriental in distribution, yet there art 1 

 well-defined groups inhabiting the seas of the West Coast of 

 Africa, and the West Indies.
