Hah. llakodaili, 5 fathoms. 



The dimensions of this species, whieh arc not given by the. 

 author, are, length 43 milL, diam. 25 ; aperture oval, purplish 

 within, 11 mill, long, G] broad. Both the length and breadth 

 of the shell will vary considerably according to the extent of 

 the closed canal and the longitudinal varices ; but the size of 

 the a])erturc is more constant. 



22. Murex [Cerastoma) enJermonis, sp. nov. 



Testa ovata, spira turrita, fuscescens; anfractus 6 supcrne decliviter 

 tabulati, pauhilum supra medium aiifjulati, infra aiigulum coii- 

 vexiusculi, varieibus 7 laciniatis supL'rncquo uuciuatis iiistructi, 

 liris spiralibus intcqualibus scabrosis cincti ; rcgio innl)ilicalis valdo 

 perforata ; apertura ovata, intus fusco-purpurea ; labrum varice 

 ultimo fimbriato incrassatum, intus denticulatum, raarginc serra- 

 tum, versus basim den to magno prominent! munitum ; columella 

 ca^ruleo-alba, medio fusco-purpureo maculata; canalis clausus, 

 breviusculus, leviter rccurvus. 



Long. 33 mill., diam. 14. 



Hab. Endermo Harbour, Yesso, 4 to 7 fathoms, sandy 

 mud. 



Some of the spiral lirations, that at the angle of the whorls 

 and three or four others in the last whorl, are much larger 

 than the rest, and with the varices produce a coarsely cancel- 

 lated aspect. The base of the prominent tooth is purple-brown, 

 and the point white. 



Murex taliemvhanensisy Crosse, and M. inornatus^ Rdcluz, 

 are allies of this s])ecies ; but both lack the labral tooth. 



It is only in young specimens that the varices are produced 

 upward in a somewhat hooked manner ; in the adult state the 

 extremities are generally worn otf.

This species, which was founded upon a specimen in very 

 bad condition new in the ]\Iuseum collection, is allied to 

 C.foliatvm^ Gmelin, from Sitka, A'ancouver, and other loca- 

 lities on the west coast of North America. 



The specimens dredged by ('a])tain St. .John at the ab()\'e 

 hicality arc in good condition.
