TleadSf ; depth 2| ; eye 5A; interorbital space flat, 12 in head, I diam- 

 eter of eye; maxillary 2 in head, equal to pectoral fin; .i>ill rakers 9 + 20, 

 the longest I length of eye. D. 72 to 83; A. 58 to 64. (In 7 specimens 

 examined the rays are : Dorsal 72, 79, 81, 81, 82, 83, 83 ; anal 58, 60, 60, 62, 63, 

 63, 64.) VertebriB 10 + 28; scales weakly ciliated, with small accessory 

 scales, 105 in the lateral line; length of the arch contained 4 times in 

 straight part of lateral line, 2 in head ; height of arch 4i in head. Fonr 

 of the 7 specimens are sinistral. Color pale chocolate brown. Specimens 

 small, 6 to 9 inches in length. Taken at Shoal Point, at mouth of the 

 Colorado River, Mexico, by the United States Fish Commission steamer

 by its numerous fin rays and many gill rakers. It is nearest related to

Head 41; depth 2!. D. 70 to 75; A. 54 to 60; scales not very small, 

 about 100 in course of lateral line; interorbital space rather broad and 

 ilattish, f diameter of eye; eyes small, 5 J in head; gill rakers rather short, 

 4 + 15, the longest al)out 'j; eye; pectoral 1^ in head; curve of lateral 

 line high and short, 4 in straight part, its height If in its length; mouth 

 moderate, the maxillary 2i in head; teeth rather few, the anterior canines 

 large. Color dark brown, more or less mottled and spotted with paler. 

 South America; said to range northward to Guatemala. Here described 

 from numerous specimens from Rio Janeiro and from Maldonado, in the 

 Museum of Comparative Zoology. The locality "Guatemala" given by 

 Giinther seems to be somewhat doubtful, and the species may not occur 

 in West Indian waters at all. (hrasilicnKis, living in Brazil.)
