collected in eight fathoms, off Wednesday Island, Cape York) 

 as Ginelin's species, I mean simply that it agrees with shells 

 bearing Gmelin's name in the British Museum. My own 

 opinion is, that these are the same as others marked C. 

 Laniai'ckii (Gray), and that both are distinct from C. erosa 

 (L.), of which Dillwyn (Vol. I., p. 461, No. 50) regards 

 Gmelin's species as the young, while Deshayes simply unites 

 them, followed herein by Gray {Zool. Jour. Vol. I., p. 504), 

 who, however, at the same time resuscitates the Cyprcea 

 niiliaris (Gm.) in the form of two new species, C. Laniarckii 

 and C. Listeri, of his own making, but one of which at least, 

 if they be good species, ought to have borne Gmelin's name." 

 He then quotes Kiener, Reeve, Sowerby, and Wcinkauff as 

 further complicating the question. 



I think the following distinctions amply serve to diffe- 

 rentiate successfully any examples of the species that puzzled 

 Mr. Watson : — 



C. niiliaris (Gmel.). A^^z^^r possesses lateral spots ; dorsal 

 surface covered with small white round spots, which are 

 never eyed, or, at all events, extremely rarely. 



C. Lamarckii (Gray) always has lateral spots, dorsal 

 surface with spots larger, round, and often ocellated. 



C. Hnngerfordii (Sowb.), 1888. This very handsome 

 addition to the genus, procured by Dr. Hungerford at 

 Hong Kong, is conspicuous for its pyriform shape and coronal 

 of spots wreathing the dorsal surface. Sides white enamelled, 

 thickened. Teeth fine, about twenty-four labial. Base as in 

 C. ca r7zico lor {D\xc\os). Long. ly. inch ; lat. Js inch. I think 

 should be placed between onyx, spadicea, and p/iysis ; to 

 var. achatidea of this latter it approaches, but not very 

 nearly. 



C. subviridis (Reeve). Conch. Icon., pi. xii., f 48 ; 

 Sowb., Thes. Conch., pi. xxii., 176 — 178. Differentiated 

 successfully by Mr. Reeve in 1835, having till then been 

 confounded with ei^rones. A local species ; the dorsal
