FISHES OF THE PHOElSriX AND SAMOAN ISLANDS 33 



This new species differs from all others in the genus Uropterygius 

 that have a single nasal opening over the eye and two rows of teeth 

 on the jaws in its color pattern of light-brownish cross bands or bars 

 on upper sides separated by pale interspaces dorsally and roundish 

 blotches along the midaxis. 



Named reidi in honor of Earl D. Reid, senior scientific aide, division 

 of fishes. United States National Museum, in recognition of his ichthyo- 

 logical contributions and help in connection Vv'ith the first sorting of 

 my collections from the Phoenix and Samoan Islands.

The young of this species have but two rows of maxillary teeth and 

 two rows of mandibular teeth. At a total length of from 250 to 350 mm. 

 the extra rows of teeth appear. The vomer begins with a single row 

 and in very large ones may have three rows of teeth anteriorly. No 

 doubt other species of this type of eel have dental changes occurring 

 with increase in length and age.
