 white. 



West Indies, Central America, Florida. 

 The young of this species has been described under the 

 name of N. pi^oxima, C. B. Ad. (fig. 59). N. lemniscata, Phil, 

 (fig. 60), and N. affinis, Busch (fig. 61), appear to me to be 

 merely j'oung. faded-out examples of this species, although the 

 first has been identified somewhat doubtfnlh- with a West African 

 shell (Jahrb. Mai. Gesell., iii, 244). Another synon^an is N. 

 pennafa, Schroter. 



N. ALA-PAPiLiONis (Chemn. in part), Auct. PI. 4, figs. 62-6'7. 



Slightly flattened at the suture, umbilicus large, with a central 

 entering callous ridge; fleshy fawn-colored, with three or four 

 subequidistant narrow white zones filleted with chocolate, the 

 interspaces of the first and second and of the third and fourth 

 zones usually darker colored. Length, 25-35 mill. 



China, Philippines, Australia, Seychelles, Zanzibar, 



Guaymas and Cape St. Lucas, W. Coast of Mexico. 



The above remarkable distribution is fully confirmed by speci- 

 mens before me. The West Coast shells are known under the 

 name of N. zonaria, Lam,, but Carpenter acknowledges their 

 identit3\ N. crenata, Recluz (fig. 63), N. articulata, Phil. (fig. 

 64), and N. tseniata, Menke, are sj'nonj'ms. 



Yar. Broderipiana, Recluz. Figs. 65-67. 



Whorls longitudinally plicately grooved ; orange-fawn color, 

 with tliree white bands articulated with chestnut. 



West Columbia, Mazatlan. 



N. Taslei, Reel. (fig. 66), and N. iostoma, Menke (fig. 67), are 

 synonyms of this variety. The latter has been differently 

 identified, with N. marochiensis, Gmel., but Philippics figure of 

 the original t3'pe sets this (question at rest. 



N. PICTA, Recluz. PI. 4, figs. 68, 69. 



TJmbilicated , the umbilicus mostly filled hy a white entering 

 callus, smooth; orange fawn-colored, white at the suture and 

 base, covered with longitudinal short zigzag chestnut lines, and 

 two or three subequidistant narrow or broader white bands
