band, Pectoral pale, lengthwise brownish streak along upper

Two from Maui, We also include 3 Hawaiian examples in the 
Academy, 
A comparison with 3 hawaiian examples 
(Steindachner), in the Academy, shows that species differs 
in no important structural character, Examples 178 mm, long 
have 72% basal radiating striae on the scales, Its dark color 
is therefore the only remaining distinction. The Wilkes ma- 
terial being much older than that recently obtained in the 
Hawaiian Islands by the Academy, is much darker, though of 
course much paler than in our examples of I. niger, 
Cymoleytes lecluse(Quoy and Gaimard). Pay
