This Cone varies much in its colouring and raarkings. Some va- 

 rieties present fantastic figures likę Con.Augur; in others thebrovvn 

 patches are iarge and likę cloudy shapes ; in all, the brown and while 

 tessellated necklaces are to be seen, as well as the violet rim on the 

 inside of the lip. As in most of the Cones which have that peculi- 

 nrity, some individuals are much riiore granulose than others.

Sometimes the ground colour is ash-colour, with longitudinal 

 chestnut stripes.

CONUS GEOGRAPHUS. 



Varietas nana, rosea: long. 2, lat. 1 poli. 



Hab. in Oceano Pacifico. (Annaa.) 



I do not find sufficient grounds for distinguishing this shell from 

 Con. geographus. It is rather more dense in proportion to its size, 

 and the spire is somewhat more elongated and contracted than that 

 of the Iarge variety : but these differences cannot be depended on 

 as specific distinctions when set against the resemblance to Con. 

 geographus in general form, and in the texture of its markings. 



Found on the reefs. — W. J. B. 



CoNus Princeps. 



Var. a. Con. testd conicd, croced veljluvd lineis castaneis freąuen- 

 tibus longitudinalibus tenuibus inscriptd : long. 24^, lat. 1 J poli. 



Hab. ad Sanctam Elenam. 



I cannot distinguish this shell specifically from Con. Princeps. In 

 some individuals, there is a blank intervaf without any lineations. 

 The only epidermis \vhich I have seen is smooth and thin.

Var. /3. long. 2i, lat. U poli. 



Hah. ad Panamam. 



This much resembles the lašt, but the lineations are less regular, 

 and in some individuals almost entirely absent : the shell too is 

 somevvhat more ponderous than that of var. a. The only epidermis 

 which I have seen is rather thick and tufted, likę that of Coh Prin- 

 ceps.
