118 MITRA. 



brown, hair-like lines ; deep orange within the aperture ; epider- 

 mis smooth, blackish, seldom present upon cabinet specimens. 



Length, 2-4 inches. 



So. and W. Australia. 



Specimens are not usually over two inches in length. M. 

 buccinata, Quoy, described ten years later, is identical. 



M. DECLIVIS, Reeve. PL 34, figs. 39, 41. 



Whorls smooth, with very faintly impressed revolving lines, 

 angularly bent around the upper part; ashy flesh to orange- 

 color. Length, 2 inches. 



Australia. 



The locality is given by Sowerby ; it was unknown to Reeve, 

 whose specimen was in the Korris Collection. The epidermis 

 is said to be very black, and there is no trace of the brown 

 revolving lines of M. glabra ; still I strongly suspect that this 

 will prove to be a deformed specimen of that species. 



M. FULGURITA, Reeve. PI. 34, fig. 43. 



Revolving strise closely punctured ; yellowish bay, slightly 

 banded with pale longitudinal streaks. Length, 2 inches. 



Habitat unknown. 



A common enough but characteristic species, of which excel- 

 lent specimens are before me. 



M INQUINATA, Reeve. PL 34, figs. 40, 44. 



Whorls encircled by distant, punctate, impressed lines ; 

 whitish, tessellated longitudinally with chestnut-brown, some- 

 times broken up into quadrangular spots by the revolving 

 sculpture. Length, 2-3 inches. 



Japan (M. Wrighti). 



Described from a single specimen without locality. It is 

 difficult to point out distinctive characters from the last species, 

 and I suspect that they are identical ; M. Wrighti, Crosse (fig. 

 44), is evidently the same species as inquinata. 



M. BARBADENSIS, Gmelin. PL 35, figs. 45, 46, 48, 49. 



Yellowish brown, polished, sometimes faintly, narrowly zoned 

 with chestnut, flaked here and there with white. 



Length, 1-1-75 inches. 



West Indies, on coral reefs. 



M. tessellata, Kiener (fig. 48), is a short shell of this species,
