ALEPOCEPHALUS FUNDULUS. 293 
Total length of the largest specimen twelve inches. 
Deep black over the surface and on the linings of the interior. 
Further differences between this form and A. fundudus are seen in the 
shorter head, shorter snout, obsolescent ridges along the top of the head, 
sinaller number of branchiostegal rays, and larger number of ventral rays.

Elongate and compressed in body and head, greatest depth one half the 
length of the latter. Head length one third of the distance from the snout 
to the base of the caudal, width seven tenths of the depth; lower profile 
nearly horizontal, upper in a very low arch above the orbits; crown of 
moderate width, somewhat concave transversely. Snout one and one third 
times as long as the eye, narrow between the nostrils, concave from the eye 
forward, broadened at the mouth, blunt at the end, with a sharp projection 
below the mandibular symphysis. Eye large, one and one half times the 
interorbital space, shorter than the snout, nearly one fourth as long as the 
head. Mouth large, rising but little forward, cleft to the suborbital region ; 
maxillary broadened and rounded posteriorly, sharp edged and toothless 
below, edging nearly half of the mouth, extending below the anterior third 
of the eye; edges of premaxille turned downward. Teeth small, sub- 
conical, on premaxille, palatines, and dentaries; absent from maxilla, 
vomer and hyoid. Opercles broad, thin, membranous toward the edges, 
longer below the middle. Gills four; lamelle short, narrow ; membranes 
not united, free from the isthmus; openings very wide ; rakers seven plus 
tourteen, broad, thin, less than half as long as the eye. Pseudobranchixe 
well developed. Pyloric cxea fifteen. Lateral line very distinct. 
Scales small, strong, rather firm, slightly roof-shaped, edged with mem- 
brane ; those of the lateral line narrower. Head scaleless. 
Dorsal origin near five eighths of the distance from the snout to the end 
of the caudal, little backward of a vertical from the vent; base shorter than 
that of the anal. Vent midway from the bases of the pectorals to the bases 
of the median caudal rays. Origin of the anal slightly backward of that
