1898. No. 1. LYCODES SARSII. 15 
The dark lines from the eye to the nostrils have almost entirely 
disappeared. 
Colourless (whitish) remain but the lower jaw, the back 
portions of the upper jaw, and the margin of anus. 
The belly is of a darker hue than the other portions of 
the body. The mouth cavity is blackish. 
At this stage (in which the scale-covering is complete) the 
scales nearest the dorsal and anal form 3—4 regular horizontal 
rows, whilst (as in all other Zycodes) the scales are elsewhere 
distributed without order over the body. These rows are best 
seen at some distance behind the commencement of the dorsal 
and anal, 
Lateral Line and Slime Pores. 
The lateral line is ventral, and indistinct, and difficult to trace along 
most of its course. It is more perceptible in the front portion, especially 
on the neck (where the body is bare). 
It rises in the neck, a little above the upper flap of the gill covering, 
and runs obliquely down towards the anus, whence it follows the ventral 
line for some way along the tail. In the largest individual where the 
scales lying nearest to the ventral line form three regular rows, the lateral 
line runs just above these rows. The distance which separates each pore 
of the lateral line is about as great as that between each scale. 
No trace can be found of any medio-lateral line. 
On the head and neck the slime-pores form very perceptible lines. 
A row of 8 pores runs along each side in one line from the eyerto 
the commencement of the side line. 2 pores form a transverse line on 
the neck between the 5th pair. 
On the preopercle 4 pores extend downwards, and continue to run 
forwards in the large slime-holes which (in all Zycodes) run along the 
upper jaw. 
These large slime-holes number 5 or 6 along the upper jaw, 7 or 8 
along the lower jaw. 
Food. 
In two large individuals, caught in the Arendal Channel on the 28th 
July 1897, the stomachs contained small Molluscs, viz., several specimens 
of Yoldia lucida, a few Yoldia frigida, and a few young of Peeten 
abyssorum, all being entire.
