NKRITINA. 55 



area greenish white, convex, wide, margin sinuate and minutely 

 dentate. Diam. 7*5 mill. 



Florida, West Indies, Mediterranean Sea. 

 It is N. pallidula (DaCosta), Risso, N. Feuilletii, Audouin. 



N. RANGIANA, Recluz. PL 18, figs. 89-92. 



Somewhat less oblique than X. viridis, usually with a subangu- 

 lated shoulder on the body Avhorl, greenish, occasionally varying to 

 yellow or rose color, with short white flames below the suture, and 

 spiral bands formed of longitudinal white lines, occasionally coal- 

 lescing, or absent, and sometimes intermingled with reddish spots in 

 spiral series ; columellar area convex, wide, white, margin distinctly 

 toothed. Diam. 8 mill. 



Red Sea, Indian Ocean, Madagascar, Mauritius, Philippines, 

 Australia. 



I think that the unfigured N. puella, Gould, from the Loo Choo 

 Is., and N. viridissima (figs. 91, 92), of Tapparone Canefri, fall 

 within the range of variation in form and color usually attributed 

 to N. Rangiana. The latter is a New Guinea species. 



N. SOUVERBIANA, Montrouzier. PL 18, figs. 93-97. 



Smooth, shining, corneous yellow, variously longitudinally stri- 

 gate, fasciculated, or reticulated with black lines, sometimes inter- 

 rupted to form spiral bands, and three or four spiral series of white 

 maculations ; columellar margin sinuate and minutely denticulated, 

 area convex. Diam. 5-7 mill. 



New Caledonia, New Guinea, Pt. Jackson, Australia. 



It is N. semen, Tapparone-Canefri (figs. 96, 97), N. pulcherrima, 

 Angas (figs. 94, 95). 



It is possibly only a variety of N. Rangiana. 



Var. HELLVILLENSIS, Crosse. 



Besides the brown or black strigations and white maculations, 

 there are two or three orange bands. 



N. PAULUCCIANA, Gassies. PL 18, figs. 98, 99. 



Moderately thick, shining, white, yellowish or light pink, dis- 

 tantly or closely reticulated with red or black, sometimes with spiral 

 bands ; aperture yellowish, columellar margin edentulous, area sub- 

 granular. Diam. 4'5 mill.
