I think it not unlikely that this form will prove to be only a 

 color variety of N. puUigera, from which it is distinguished mainly 

 by its lighter color and more prominent and diversified markings. 

 Like that species it has its varieties depending upon the appression 

 or erection of the sutural edge, color of interior, etc ; and as in that 

 species, so far as these differences have caused separate names to be 

 given them, I have treated them as varieties-si mply for convenience. 



This form is N. pulligera, Quoy and Gairnard, JV. Delestennei, 

 Recluz. 



Var. Bfxkii, Recluz. Figs. 20, 21, 25.

 synonmys.
