We have the following specimens from Paumotu Islands: — 



Nos. A54, 05776, 05777, M. C. Z. 29581, 4 to 9^ inches long from Fakarava, 

 and 05787, two small specimens from Makemo, M. C. Z. 29471. 



In No. A54 the color in alcohol is dark olive-green, thickly marbled with 

 darker ; fins at the end of the tail not noticeably lighter. 



In the smaller (young) examples, in which we can detect no other tangible 

 differences, the color is uniform purplish brown without evident marbling, fins 

 at the tail yellowish white. 



U. marmoratus and concolor are very probably the same species. In very 

 young individuals we can find no differences except a slight difference in color 

 and these do not show in alcoholic specimens.
