Do 12-> Wee ES) 
Length of head equals its distance from ventrals, and is 7.3 
in total length. Snout produced spatulate nearly equals post 
ocular part of head, its pre-oral portion being about 2.3 in its 
length. The eye is contained about 4 times in the oe and 
is equal to the interorbital space and about 4 post-ocular portion 
of head. The maxillary scarcely reaches the eye. 
The dorsal is a little behind ventral and consists of 12 rays, 
the first small, about + the length of the second. The rays are 
unbranched ; the succeeding are branched with the exception 
of the last two. V.entrals 1} times in pectorals. 
Seales of lateral line enlarged, provided with photophores, 
15 before the ventrals and 28 in front of anus. There appear 
to be at least 2 series of scales between the lateral line and the 
anal fin at its anterior end. 
Mr. Regan, who has been kind enough to examine a duplicate 
of this specimen, is of opinion that it agrees in every way with 
H. affinis, which is probably not, however, distinct from 
H. rostratus.

Halosaurus sp. 
A single specimen of this species was procured off Cape Point 
(N.E. + N., 46 miles) by shrimp trawl, from a depth of 760 
fathoms. It is apparently different from the two species de- 
scribed above, the ventrals being well in advance of dorsal, 
and the end of the maxillary falling under the posterior margin 
of the eye. Owing to the condition of the specimen, due to 
damage in trawl net, further description or specific a 
tion might be misleading.
