 26. p. 225. 



Two specimens, Nos. 3309-10, 5 and 5 u inches long from Rikitea, Manga

The fins of two of the smaller specimens and of the largest are typically 

 colored, varying a little in intensity. In the other specimen the spinous dorsal 

 is merely mottled and streaked with brown; the white marks on the anterior 

 dorsal membranes are distinct, no black below white on first three membranes; 

 the axil of the pectoral in the smallest specimens with a slightly brownish tinge 

 formed of fine punctulations; the next in size has the axil about same on one 

 side, darker on other; the third has the axil quite dark brown, and in the largest

Two specimens, No. 3294-3295, M. C. Z. 29669, 10 and 9i inches long from 

 Rikitea, Manga Reva. 



The body colors are more hke those represented in Bleeker's Atlas, 9, tab. 

 360, Trachichth., 6, fig. 5, of H. sammara, than of his figure of H. operculare, 

 tab. 358, Trachichth, 4, fig. 3, and of Gunther's figure of H. operculare in Fische 

 der Siidsee, taf. 66, fig. A. Our specimens agree very well with the color de- 

 scription given by Jordan and Seale {loc. cit.).
