150 CHRYSAME. 



M. PICEA, Pease. PI. 58, fig. 685 ; PI. 44, fig. 288. 



Decussated by longitudinal ribs and revolving striae ; chestnut- 

 brown with a superior narrow white band. Length, 7-9 mill. 



P(tum,otus, Sandwich Islands. 



Sowerb}' figures a shell (fig. 288), under the same name, but 

 without author, which may be a dark, unhanded specimen of 

 this species ; if distinct, it must receive a new name. 



M. IJziELLiANA, Crosse. PL 44, fig. 289. 



Uniform yellowish brown ; cancellated. Length, 1 inch. 



? Taliiti. 



Sowerbv thinks this may be synonymous with M. lugubris, 

 but it seems to have characters of sculpture and color which 

 should distinguish it — at least until better known to oon- 

 chologists. 



M. PERRUGINEA, Lam. PI. 44, figs. 279, 280, 290. 



Yellowish or whitish, longitudinally stained with chestnut- 

 brown, the markings interrupted so as to show a light band on 

 the peripher}-. Length, 1-5-2-25 inches. 



Philippines ; Polynesia, coral reefs ; Mauritius. 



The animal is cinereous or pale luteous and slightly varied 

 with reddish brown. M. rubritincta, Reeve (fig. 280), is a short, 

 stout form, connecting with ferruginea.^ by a series of transi- 

 tional forms. M. clara, Sowb. (fig. 290), an immature specimen, 

 with a slight shoulder, appears to be merely a slender variety. 



M. PUDiCA, Pease. Pl. 44, figs. 291, 292. 



With revolving ridges and longitudinal striae ; whitish or 

 yellowish, variegated with smoky brown. Length, •7-9 inch. 



Sandioich Islands. 



With this I unite M. nuxavellana, Dohrn, an unfigured species 

 which its author concedes to be a synonym ; also 31. subrostrata, 

 Sowb. ('fig. 292 \ These are all immature shells, and are evidently 

 related to M. ferruginea. 



M. CANDIDA, Reeve. PI. 44, figs. 293, 294. 



Whitish to chestnut, closely ridged, finely longitudinally 

 striated between the ridges. Length, '8 inch. 



La Quay r a, So. America.
