STRIGATELLA. 155 



M. MACULOSA, Reeve. PI. 45, figs 327, 328. 



Chestnut color under a deciduous corneous epidermis, a broad 

 white band above the middle, and brown revolving lines, punctate 

 with white towards the base. Length, 15-21 mill. 



Red Sea, Australia, Polynesia. 



M. Arabica, Dohrn (fig. 338), does not differ. Typically it is 

 distinct enough from M. litter ata, but there are varieties which 

 certainly approach extreme examples of that species very closely. 



M. TRISTIS, Swainson. PI. 45, fig. 329. 



Shell white or light-chocolate, under a persistent, smooth dark 

 olivaceous or black-brown epidermis, with a yellowish band at 

 the top of the whorls; frequently slightly round-shouldered, and 

 rudely folded at the sutures, forming obsolete tubercles ; aper- 

 ture chocolate-colored. Length, '75-1-25 inches. 



Galapagos Is. ; Panama to Mazatlan. 



M. CHRYSOSTOMA, Swainson. PL 46, figs. 330, 331. 



Whitish or yellowish, tessellated or strigated longitudinally 

 with orange-brown or chocolate, interrupted by a white, irregu- 

 lar band on the periphery. Length, 1-35-2 inches. 



Polynesia, Philippines, Mauritius. 



Kiener has figured this species m error for M. contracta, Swn. 

 (= abbatis), and Phillippi, discovering that this figure did not 

 represent Swainson 's species, has called it M. Kieneri. 



M. SCUTULATA, Lam. PL 46, figs. 332-337. 



Chocolate-brown, sometimes with merely an irregular, or 

 interrupted yellowish or whitish band below the sutures ; 

 sometimes irregular small spots of the same color are on the 

 lower portion of the body-whorl ; sometimes these spots unite 

 longitudinally into strigations above and below, but always 

 leaving a central chocolate space which thus becomes defined 



as a broad band. Length, 1-1'75 inches, 



Philippines, Polynesia. 



M. amphorella, Lam. (fig. 334), M. decurtata, Reeve (fig. 335), 

 and M. oleacea, Reeve (fig. 336), and M. sertum, Duval (fig. 337), 

 are synonyms. 



M. LITTERATA, Lam. PL 46, figs. 338, 339.
