CEROSTOMA. 113 



M. GouLDi, A. Adams. 



Ovate fnsifoi'm, fuscous, sparsely maculated with chestnut ; 

 spire acute, whorls flattened arid somewhat shouldered ; trans- 

 versely lirate, the lines unequal ; varices shortly foliated, folia- 

 tions each ending in a posterior recurved spine ; aperture ovate, 

 closed, the lip margin broadly fimbriated ; canal straight, closed, 

 longer than usual in the group. 



No dimensions given ; not figured. 



Tsu-Sima, Japan. 



M. CENTRiPUGA, Hiuds. PI. .34, fig. 3*7*r. 



Light brown. Length, Vlb inches. 



W. G. of Verugua, N. Grenada ; 



dredged in 52 fathoms, sandy floor. 



M. EURYPTERON, Rccve. PI. 34, figs. 3t4, 879. 



Light yellow. Length, 2 inches. 



Japan. 



M. expansus, Sowb. (fig. 3t9), supposed to come from China, 



is evidently the same species. 



M. TRiALATUs, Sowb. PI. 34, figs. 372, 375 ; pi. 3.5, fig. 387. 



Decidedly too close to M. eurypteron. Light yellow, usually 

 banded with a darker color, The want of a tooth on the lip, 

 the usually' smaller size, and the strong development of the 

 single node between the varices suffice to distinguish it from M. 

 foliatus. Length, 2'5-3"25 inches. 



Todas Santos Bay, L. Galifornia (H. Hemphill). 



M. Galifornicus^ Hinds (figs. 375, 387), is a sjmonym. 



This shell is wrongly referred to Muricidea by Carpenter and 

 others ; it has three varices, and its relationships are certainly 

 with Cerostoma. Carpenter in his Mazatlan Catalogue describes 

 M. f erinaceoides var. indentata, which I think maybe a sj-nonym 

 of M. Calif ornicus. His variety has three varices, whilst the 

 true M. erinaceoides (= lugxd)ris^ Brod.) has six. 



M. FOLIATUS, Martyn. PL 34, figs. 370, 371, 373. 



White, usually banded with light chestnut. Length, 2-3 

 inches. 



Sitka to Santa Barbara, Gal., Asia ?
