210 PSEUDOMUBEX. 



C. NUX, Reeve. PL 66, fig. 368, 374. 



Shell white, without and within. Length, '75-1 inch. 



Mazatlan to Panama, Gallapagos Isles. 



This solid, white little shell has many synonyms ; among them, 

 C. osculans, C. B. Ad., C. distans, Carp., C. niveus, C. Galifor- 

 nica and G. asper of A. Ad., and C. parva of E. Smith (fig. 374) 

 from Grallapagos. 



C. CORONATA, Barclay. PL 66, figs. 373, 372. 

 Light rose-purple, darker within the aperture. 



Length, -88-1-25 inches. 



Mauritius. 



The form of this shell is very distinct. I unite with it C. 

 Barclay ana, H. Ad. (fig. 372), from same locality ; being merely 

 a better grown or older specimen. E. A. Smith has referred to 

 C. Barclayanu, a specimen collected at the Andaman Islands, 

 and removes the species to the genus Muricidea. 



[Genus PSEUDOMUREX, Monterosato.] 



An aberrant form, referred by authors to Murex, to Corallio- 

 phila and to Latiaxis. I cannot find any good characters by 

 which to separate it from Coralliophila. It includes four species 

 and numerous varieties, all inhabiting the Mediterranean Sea. 



C. BRACTEATA, Brocchi. PL 66, figs. 378-380, 384, 386. 



Whitish or yellowish. Length, 1-1 '3 inches. 



Mediterranean ; found on corals at considerable depths. 



Very variable in form and ornamentation. Monterosato has 

 distinguished six varieties, which have mostly been described as 

 species : 



Var. 1. G. lamellosa (Jan), Phil. (figs. 378, 385). 



Var. 2. C. minor, Mont. 



Var. 3. C. lacerata, Desh. (fig. 379). 



Yar. 4. G. Babelis, Requien. (fig. 380). 



Var. 5. G. Panormitana, Mont. 



Var. 6. C. brevis, Bl. (fig. 384). 



C. MEYENDORFFI, Calcara. PL 66, fig. 382. 



Whitish. Length, 1-1*5 inches. 



Mediterranean, Canaries^ Madeira.
