attend some difference in function as compared with the other forms; the 
differentiation in structure attests this, but whether in the direction of tac- 
tile, electrical, or light producing facilities cannot be deterinined at present. 
The glandular layer is deeper near the middle of the band, and it may be 
the centra are obscured by partial maceration. Apart from the shapes and 
absence of centra, accord with the system in Gadus, Phycis, and the Brotu- 
loids is evident. The mucus chambers on the top of the head are large, 
larger than on the sides. Along the courses of the tubes, at their edges or 
over them, there is a row of small closely set pores, most noticeable close 
above and below the nostrils and forward from them to the end of the snout. 
Top of head, middle line of back, dorsal and caudal brown; upper por- 
tions of flanks brownish; sides and lower surface of head and lower portions 
of body silvery to whitish; linings of gill chamber and abdomen black ; pec- 
torals marked with blackish or black posteriorly.

Depressed and pointed at the snout; compressed and narrow in the body 
and tail; body cavity more than half of the total length. Head about two 
ninths of the total, or two thirds as long as the distance between ventrals 
and anal, wider than deep, narrower on the top, flattened to slightly con- 
cave at the interorbital region, with a keel-like suborbital ridge. Snout 
longer than the eye, less than one third of the head, extending beyond the 
intermaxillaries one half the length of the eye, rather sharp at the end, 
broad and flat, edges continued back in a low keel along the side of the 
head below the eye. Nostrils small, close together, immediately in front 
of the eye, posterior much larger than the anterior, from which it is sepa- 
rated by a valvular flap. Mouth very wide; maxillary narrow, reaching 
a vertical from the hind border of the orbit. Teeth small, in narrow villi- 
form bands on the jaws and in a small bunch on the vomer. Eye large, one 
fourth as long as the head, equal to the interorbital space, one and one
