Holocentrus diadema Lachrbpe. 
Hist. Nat. Poiss., 1802, 4, p. 335, 372, 374, pl. 32, fig. 3; Jorpan & Seate, Bull. U.S. Bur. Fish., 1906, 
25, p. 225. 
Two specimens, Nos. 3309-10, 5 and 5 te inches long from Rikitea, Manga 
Reva. 
In smaller specimens the spinous dorsal membranes and the axil of the 
pectoral are very dark brown; in larger specimens the membrane of the dorsal 
is lighter. 
Five specimens, 4% to 5$ inches long from Manga Reva, coral reef. M. C. Z. 
29696 (2 specimens). 
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 
it is a very dark brown, almost black. 
Holocentrus sammara (ForskKAt). 
Jorpan & EverMAnn, Bull. U.S. Fish. Comm., 1905, 23, pt. 1, p. 155, fig. 56. 
Sciaena sammara ForsxKA&u, Descrip. Anim., 1775, p. 48. 
Four specimens Nos. 3296-99, 62 to 72 inches long, and three specimens 
42 to 73 inches long from coral reef, all from Manga Reva. M. C. Z. 29703 
(2 specimens). 
Holocentrus opercularis (Cuvier & VALENCIENNES). 
Jorpan & Seaxe, Bull. U.S. Bur. Fish., 1906, 26, p. 227. 
Holocentrum operculare Cuv. & Vat., Hist. Nat. Poiss., 1831, 7, p. 377 (501). 
Two specimens, No. 3294-3295, M. C. Z. 29669, 10 and 93 inches long from 
Rikitea, Manga Reva. 
The body colors are more like 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 Giinther’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.).
