OCINEBUA. 12*7 



The varices vary in iiumbor. Can this l»o a depauperate state 

 of M- Japonicus ? 



M. TANTILLUS, A. Ad. 



Small, ovately fusiform, white, with laciuiated lamella? widely 

 cancellated with crispate lirse ; whorls six, angulate in the middle ; 

 aperture narrow, sub-ovate ; margin of lip thickened, wideh' re- 

 flected, sub-sinuate behind ; canal very short. 



Satanomosaki, Jwp. ; 55 fathoms. 



Described as a Trophon^ but the widely margined lip shows it 

 to be a relative of M. Japonicus, etc. It ma}^ be the j^oung of 

 one of the preceding species. Not figured. 



M. SCALARINUS, A. Ad. 



Ovate, rimate, pallid fulvous, tinged with red ; spire elate, 

 acute, as long as the aperture ; whorls five, with five or six 

 elevated varices and revolving lamellose larger and intermediate 

 crenulate smaller lirae ; suture profound ; aperture ovate, sub- 

 patulous, inner lip smooth, arcuate ; outer lip externally variced ; 

 canal moderately open, inclined to the left. 



Length, 1 inch, lat. •25 inch. 



M. MONACHUS, Crosse. PI. 37, figs. 449, 450. 



Chestnut-color, variegated with white ; four varicose, varices 

 white ; obsoletely tuberculate between the varices. 



Length, 1-8 inches. 



China, Japan. 



It is just possible that this may l)e a var. of Japonicus ; on the 

 other hand it recalls the genus or group Vitularia. The Japanese 

 use it as food. Sowerby (Thes. Conch.) cites author, work and 

 localit}^ incorrectly for this species. 



M. FALCATUS, Sowb. PI. 38, figs. 457-459. 



This has somewhat the appearance of M. ( Cei^ostoma) foliatus^ 

 Gmel., but differs in the number of varices and in their hooked 

 spinous prolongations from the shoulder of the whorls. Light 

 yellowish-brown, sometimes tinted with darker color on the 

 middle of the body. Length, l-GO inches. 



Japan. 



M. aduncuH, Sowb., (fig. 459), is a variety, and 31. acantho- 

 phoriis, A. Ad., (fig. 458), appears to be merely a depauperate
