Eleotris pictus, Jord. & Everm. Bull. U.S. Nat. Mus. xlvii, 1898, p. 2201 *, 
Depth of body 5 to 6 in the length, length of head 3 to 33. A small concealed antrorse spine at the angle of 
the preoperculum. Dorsal VI, 18. 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.

Panama !.—Kcuador. 
Here described from several specimens, measuring up to 380 mm. in total length, 
from the Rio Presidio and from Ecuador. This species is very close to the Atlantic 
E. pisonis, which has a deeper body and a shorter and broader head. 
3. DORMITATOR, Gill, 1862. 
Dormitator, Jord. & Everm. Bull. U.S. Nat. Mus. xlvii. 1898, p. 2199. 
Body oblong, compressed ; head broad, obtuse. Mouth moderate, more or less oblique; jaws equal anteriorly, 
with bands of small, movable, slender teeth with truncate apices; palate toothless. Eyes rather 
small; interorbital region broad. Gill-openings moderately wide, extending forward nearly to below 
the angle of preoperculum, 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 second 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 pectorals, 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.
