ZEUXIS. 38 



The synonyms are N. Panamensis, C. B. Ad., N. Fontainei, 

 d'Orb. (tig. 102). and N. moexta, Hinds (fig. 101). I give the 

 locality Viti Islands on the authority of Mr. A. Garrett, and 

 Solomon Is. on that of Mr. John Brazier, who personally col- 

 lected it at those pla< 



A". Fontaine i. d'Orb. (fig. 102), from the Coast of Peru, is 

 larger than the Panama specimens of exilis, yet immature ; of 

 its identity there can be no doubt ; form, sculpture and colora- 

 tion being the same. 



X. COMPLAXATA, Powis. PI. 10, figs. 105-107. 



Olive or ash. with M yellow band above the periphery. Ob- 

 liquely granosely ribbed, ribs and granules frequently obsolete 

 on middle and lower portions of the body whorl. Aperture 

 dark within, but showing the light band. Length. '5 inch. 



W. Columbia, Panama. 



Proportionally wider than N. e.?://i>, but with the same colora- 

 tion, its form being intermediate between that species and N. 

 te<i>ila, Reeve. N. sccibriuscula, C. B. Ad., and N. Wilsoni, C. 

 B. Ad. (fig. 106), are synonym^. Possibly N. gemma, Phil. (fig. 

 107), may also belong here, as suggested by Mr. Mnrrat.

Pacific Islands. 



Evidently immature, and the figure, rather inaccurate. It is a

 remarks upon its resemblance i> A", ('nn'rri.
