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 coronal 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. 3T, 



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 speckled with 

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

 scopically ciliated, especially at the bluntly pointed tips. Mi- 

 Jeffreys has seen the barrel-shaped, strongly corrugated ov; 1 

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

 ova being elliptical and prismatic. Monterosato makes tw< 

 varieties of this species, the first being Fasus minutus Desh. 

 F. Titii, Stossich ; the second, Fuxtis Hellerianus Brusina 

 Murex Weinkaujfianus, Crosse, (fig. 441). 



M. badius, Reeve, (fig. 407), and M. pistacia, Reeve, (fig. 405), J 

 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 l>y 

 Monterosato. It is found in African sponges. 



M. SCALAROIDES, Blaiiiv. 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. scalaroidex, Bl.
