fusiform contour and thin texture. It differs from G. striata 

 by its sculpture and the absence of distinct dark varices. G. 

 plicatula is a smoother, more obese shell, with shorter aper- 

 ture. No other South American species is nearly related. ' '

In typical E. plicatula the spire is straightly conic, its out- 

 lines not concave near the apex; the color is reddish-brown, 

 darker towards the summit. The outer lip is drawn forward 

 near its upper insertion, and the columella is moderately con- 

 cave, less so than in the Venezuelan race. Strebel gives the 

 measurements of Sonson examples : length 60.5, diam. 27.5, 

 aperture 33.25 mm., whorls 6%, and 44, 19.75, 23.75 mm., 

 whorls nearly 61/4.
