yelagic or bathypelagic. A large shark appears to be the southern 
representative of the arctic Somniosus microcephalus ; the Mycte- 
phide are Myctophum antarcticum, a widely distributed species, 
and Lampanyctus brauert, previously known from off Coats Land 
and from N.H. of the Falklands. A new genus and species, 
Notesudis hamiltoni, is of doubtful position, but seems to have much 
in commen with Scopelosaurus, Bleek., and IJdiacanthus aurora, 
described as new, appears to be a synonym of J. niger, Regan. 
Examination of the type of the last-named species shows that it 
has the number of vertebre and of branchiostegals given by Waite ; 
of the supposed differences the backward position of the ventrals 
and mere forward position of the anal relatively to the ventrals are 
discounted by the statement that ‘‘ having floated off with the skin 
the actual position of the ventral fins cannot be ascertained with 
certainty”; differences in the preservation of the specimens and in 
method of measurement may account for the apparently larger eye 
of Jf. aurora, and the fact that the barbel is attached to the hasi- 
hyal and has no fixed point of origin in relation to the mandible 
explains an apparent difference in its position. 
The coast-fishes of Macquarie Island are of much greater interest 
than the pelagic or bathypelagic species that happened to be taken 
near it. The determination of four of the five species listed by 
Waite cannot be questioned, but the other, which he calls Nothena 
coriiceps, Var. macguariensis, appears to differ from NV. coriiceps in 
the fewer dorsal rays and broader interorbital region—just the 
characters used to define NV. rossit in my synopsis of the genus. 
Comparing the fish described and figured by Waite with examples 
of NV. rossit, of which there is now a large series from South 
Georgia in the Natural History Museum, I conclude that it belongs 
to that species, the type of which is from an unknown locality, 
but was quite likely taken at Kerguelen.

It is very interesting to find that the relationship with Kerguelen, 
more than 3000 miles distant, but on nearly the same isotherm, 
appears to be closer than with the subantarctic islands of New 
Zealand, only some 400 miles to the north-east. 
A new genus and species of Bovichthyide—Aurion effulgens—is 
described from a specimen taken in 50° 60° §., 165° E. ‘This has 
many features in common with Bovichthys decipiens, Giinth., also 
taken in the open sea (50° 8., 170° W.); but re-examination of the
