116 OCINEBRA. 



M. RORiFLUUS, Adams and Reeve. PI. 35, fig. 390. 



Light chocolate-brown, the varices white, lip-tooth prominent. 



Length, 1-3 inches. 



Corea. 

 Evidently a young shell. 



M. FESTIVUS, Hinds. PI. 35, fig. 383. 



Whitish, closely encircled by incised lines, which are brown, 

 varices reflexed, widely laminar, crossed })y close rows of elegant 

 semicircular scales. No tooth. Length, 1*5-2*5 inches. 



California. 



Subgenus Ocinebra, Leach. 



This group, as well as Muricidea, is made by Messrs. Adams 

 an omnium gatherum, including true Murices, purpuroid Murices, 

 Purpurse, Fusidse, etc. Muricidea as defined b} T them has no 

 really distinctive characters from Ocinebra, and Swainson in- 

 cluded spiecies of Trophon, Triton, etc. I have suppressed 

 Muricidea, and retained Ocinebra for a group of small Murices 

 with numerous varices and purpuroid operculum ; the species 

 having muricoid operculum are relegated to Phyllonotm, from 

 which they do not differ. A number of species the operculae of 

 which are unknown, are ranged arbitrarily in Pht/Uonofus or 

 Ocinebra, and with regard to these I claim the indulgence of 

 brother conchologists who may have similarly found themselves 

 in the predicament of being compelled to place something some- 

 where just to get it off their hands. 



. :: . ;: -. ; ;. European Group. 

 M. ERINACEUS, Linn. PI. 36, figs. 400-404. 



Four to seven Varicose, nodulous, encircled by prominent 

 cord-like, raised ribs, alternately smaller, the smaller ones 

 minutely scabrous ; varices sometimes frond ose, sometimes 

 lamellated, occasionally appressed. Occasionally the larger re- 

 volving ribs thickly overlap the varices, forming a succession of 

 elongated nodules (var. torosus (fig. 404). Yellowish-brown ; 

 whitish within. Length, l'5-2 inches. 



Europe, from Norway to Black Sea, Azores, Madeira ; range, shore to 

 30 fathoms ; fossil in European tertiaries and quarternaries.
