OCINEBRA. 119 



M. HYBRIDUS, Aradas and Benoit. PL 36, fig. 415. 



A rare shell found at Palermo. Length, '5 inch. It has 

 seven ribs forming a coronaj of spines at the shoulder ; the lip is 

 denticulate within, and the short canal is closed. 



M. ACICULATUS, Lam. PI. 36, figs. 405, 407, 408, 409; pi. 31, 



fig. 441. 



Brownish, with numerous ribs ; canal short, open. 

 Length, -5 inch. 



Channel Islands, stony and rocky ground, at low water mark and in the 

 laminarian and coralline zones. Canary and Azores Islands^ Med- 

 iterranean 4 to 40 fathoms. Fossil, Coralline Crag, England; 

 Italian tertiaries. 



The animal is coral-red or scarlet, sometimes speqkled with 

 light yellow ; the tentacles are paler in color, extensile, micro- 

 scopical^ ciliated, especially at the bluntly pointed tips. Mr. 

 Jeffreys has seen the barrel-shaped, strong^ corrugated ova- 

 capsules, attached, solitary, to the under side of the shell ; the 

 ova being elliptical and prismatic. Monterosato makes two 

 varieties of this species, the first being Fusus minutus Desh. = 

 F. Titii, Stossich ; the second, Fusus Hellerianus Brusina = 

 Murex Weinkauffianus, Crosse, (fig. 441). 



M. badius, Reeve, (fig. 401), and M.pistacia, Reeve, (fig. 405), I 

 refer to this species as suggested by Kobelt. M. pereger, 

 Brugnoiie, (fig. 408), appears to me to be very much nearer related 

 to this species than to M. erinaceus to which it is referred by 

 Monterosato. It is found in African sponges. 



M. SCALAROIDES, Blainv. PI. 30, fig. 276 ; pi. 36, fig. 416. 



Six varicose ; white or yellowish ; canal short ; aperture 



rounded. Length, *5 inch. 



Mediterranean ; rather rare. 



M. INERMIS, Sowb. PL 36, fig. 417. 



White ; the varices narrow, six in number, canal rather long, 



open. Length, '5 inch. 



Japan. 

 Has some resemblance to M. svalaroides, Bl.
