1 34 SCABRICOLA. 



M. VULTUOSA, Reeve. PI. 39, fig. 143. 



Orange-brown. Length, 1 inch. 



Isl. of Capul, Philippines (found on the reefs). 

 Closely allied to M. impressa, Anton. 



M. NUCLEOLA, Lam. PL 39, figs. 145-141, 151. 



Fulvous yellow, Length, -75-1 inch. 



Habitat unknown. 



The figures given by Kiener (fig. 145 ), Reeve (fig. 146), and 

 Sowerby (fig. 147) for this shell, are so different that they seem 

 to represent distinct species. The first, which is presumably 

 from the type, if well drawn, has but little affinity with the 

 present group ; M. unifascialis, Lam., as figured by Kiener (fig. 

 151), certainly appears to be synonymous with it. 



M. SPH^RULATA, Martyn. PI. 39, fig. 149. 



Whitish, yellowish or light brown, variously stained with dark 

 chocolate or blackish spots on the granules ; aperture orange. 



Length, 2-2 '5 inches. 



Philippines ; Polynesia. 



M. EBURNOSTOMA, Garrett. 



Creamy white, sparingly mottled with brown. The sculpture 

 is almost precisely the same as in M. sphaerulata, but it may be 

 at once distinguished from that species by its paler color, more 

 slender form and pure white aperture. 



Length 41, diam. 13 mill. 



Paumotus Isles. 



A very rare species, of which two examples were found buried 

 in sand in the upper region of the laminarian zone. Its distinct- 

 ness from M. sphserulata may well be doubted ; it has not been 

 figured. 



M. TEXTURATA, Lam. PL 39, figs. 150, 148. 



Shell variegated with white and rusty brown. 



Length, 1*25-1*5 inches. 



Philippines, Viti Isles. 

 Var. LIFOUANA, Crosse. Fig. 148. 



Distinguished from the type by its small size, stumpy form, 

 and uniform white coloring. Length, 16 mill. 



Lifou, Loyalty Isles.
