attend some difference in function as compared witli the other forms ; the 

 differentiation in structure attests this, but whether in the direction of tac- 

 tile, electrical, or light producing Axcilities cannot be deterniiucd 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 chandjer and abdomen black; pec-

Depressed and pointed at the snout ; compressed and narrow in the body 

 and tail ; body cavity more than half of tlie 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 suiall, 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
