7EUX1S. 31 



The habitat " West Indies," given by Reeve, is erroneous, as 

 is also that of u Chili," in Kiener. A goodly number of species 

 may be referred to this form with some confidence: They are 

 N. plicata, Pease (preoccupied) = N. approximata, Pse., .A 7 . 

 , Hombr. et Jacq. (fig. 78), N. mitralis, A. Ad. (fig. 79), N. 

 -ia^ A. Ad. (fig. 81), N. cinnamomea, A. Ad. (fig. 80). In 

 N. elegans, Reeve, not Kiener (fig. 82), the style of painting 

 varies considerably from the t}'pe, but I have before me a 

 similarly painted specimen, which is undoubtedly a A 7 , tsenia. 



N. CANALTCULATA, Lam. PI. 9, figs. 83-8G. 



Ash-olive, sometimes faintly two banded with chestnut ; 

 sutures channeled and frequently crenulate ; upper whorls 

 closely ribbed, ribs sometimes apparent on the back of the body 



whorl. Length, l'l-l/5 inches. 



Philippine Islands, Polynesia. 



N. Isems (Chemn.), II. and A. Adams (fig. 86) is a synonym. 



N. STOLIDA, A. Adams. PI. 10, fig. 87. 



Bluish-ash, sparingly blotched or banded with yellow and 



brown. Length, 1'25 inches. 



Habitat unknown. 



Described from a single specimen, which is evidently of ab- 

 normal growth. 



N. UNICOLORATA, Kiener. PL 10, figs. 88, 89, 90. 



Livid ash-color, sometimes stained or banded with brown ; 

 aperture chocolate-colored within. Length, 1-1*3 inches. 



Moluccas, Australia, Neio Zealand. 



A ullia-\ikc species, normally very distinct, yet undoubtedly 

 closely connected by transition forms with N. canaliculata and 

 N. tsenia. N. unicolor, Hombr. and Jacq., is identical; the 

 figure which I give (fig. 89) probably represents a similar shell 

 to that which Gmelin called N. trifasciata. N. rutilanx, Reeve 

 (fig. 90), and probably N. glauca, Dimker, an unfigured species, 

 belong here. 



N. VARICTFERA, A. Adams. PI. 10, fig. 91. 



Whitish, with two brown bands ; whorls crossed occasionally 



by M. varix. Length, 1 inch. 



Japan.
