OCINEBRA. 127 



The varices vary in number. Can this be a depauperate state 

 of M. Japonicus ? 



M. TANTILLUS, A. Ad. 



Small, ovately fusiform, white, with laciniated lamellae widely 

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

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

 flected, sub-sinuate behind ; canal very short. 



Satanomosaki, Jap. ; 55 fathoms. 



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

 to be a relative of M. Japonicus, etc. It may be the young 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 line ; 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. PL 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 be 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 

 locality incorrectly for this species. 



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



This has somewhat the appearance of M. (Cerostoma) 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 bod} 7 . Length, 1'66 inches. 



Japan. 



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

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