Depth of body 5 to G in the length, length of head 3 to 3^. A small concealed antrorse spine at the angle of 

 the prffioperculum. Dorsal VI, I 8. Anal I 8. 60 to 70 scales in a longitudinal series. Back and 

 sides obscurely spotted or clouded with blackish ; lower parts with pale spots ; fins with series of small 

 dark spots on the rays and with irregular markings on the interradial membranes.

Here described from several specimens, measuring up to 380 mm. in total length, 

 from the Eio Presidio and from Ecuador. This species is very close to the Atlantic 

 E. 2)isonis, which has a deeper body and a shorter and broader head. 



3. DOEMITATOE, Gill, 1862. 



Dormitator, Jord. & Everm. Bull. U.S. Nat. Mus. xlvii. 1898, p. 2195. 



Eody oblong, compressed ; head broad, obtuse. Mouth moderate, more or less oblique ; jaws ecpal anteriorly-, 

 with bands of small, movable, slender teeth with truncate apices ; palate toothless. Eyes rather 

 small ; interorbital region broad. G ill-openings moderately wide, extending forward nearly to below 

 the angle of prajoperculum, the gill-membranes attached to the isthmus. Scales ctenoid, rather large, 

 covering the body and the greater part of the head ; no lateral line. Two dorsals, the first of 7 flexible 

 spines, the secoiid of a slender spine and 8 branched rays; anal similar to the second dorsal, with a 

 slender spine and 9 or 10 branched rays; caudal rounded; pectoral of moderate length, symmetrical, 

 rounded ; ventrals below the base of the pect-orals, close together but not united, each with a short 

 concealed spine and -5 branched rays. 



This genus is now usually considered to contain a single species, subject to 

 considerable variation in form and colour. I find, however, that it is always possible 

 to distinguish between specimens from the Atlantic and Pacific, and, although the 

 differences are but slight, the two forms may provisionally be recognized as specifically 

 distinct.
