NERITINA. 87 



N. ZEBRA, Brug. PI. 10, figs. 93-95. 



Somewliat shining, yellowish olive or orange brown, with un- 

 dulating radiating broad black stripes ; aperture whitish. 



Diam. 21-23 mill. 



Northern So. America to Brazil; Porto Ricof, Panama?. 



I find no characters by which to distinguish this from varieties 

 of jSf. ziczac, unless it be by the less angulated patcern of the stripes 

 and their greater width ; moreover, I know of no such American 

 form, and I cannot help thinking that, at least as to some of the 

 identifications, the mistake has been made of confounding ^vith it 

 varieties of N. reclivata and N. virginea. Entirely similar shells 

 are in the Philadelphia Collection, received from Cuming as from 

 Taheiti. N. lineolata (? Lam.), of Sowb., Reeve, etc., and N. so- 

 hritia, Recluz (fig. 95), are referred here by INIartens.
