THE 23 species here recorded were taken by the “Scotia” during a short 
stay at St Helena on her return voyage from the Antarctic. Though all 
have been previously described, yet, as a result of this capture, four now fall 
to be included iu the fish fauna of the island. 
These are— 
Gonorhynchus grey. 
Hxocetus speculrger. 
Thynnus pelamys. 
Sargus rondeletw. 
Little importance can be attached to the occurrence of Hxocetus speculiger 
and Thynnus pelamys, as these are typical open Atlantic forms and widely 
distributed, though their appearance at this island seems rare. 
As Mr J. T. Cunningham (1) has already stated, the fish fauna of the 
island is extremely interesting owing to its wide relationships. Its members 
show affinities with the fishes from Ascension, Cape Verde Islands, Madeira, 
Azores, and the Mediterranean; and also with those from Brazil and the 
West Indies, and from the Cape of Good Hope. 
To Dr Harmer, Keeper of Zoology, British Museum, I wish to express 
my indebtedness for granting me all facilities to compare my material with 
the type specimens; and also my cordial thanks to Mr C. Tate Regan, whose 
method of description I have adopted throughout, for kindly assisting me 
in the identification of several of the species, and for personal supervision 
of my work. 
The following are the “Scotia” species, with a detailed description of 
two—Gonorhynchus grey and Synodus synodus. 
Gonorhynchus greyi (Richardson). 
Depth of body 73 to 10 in the length; length of head 43 to 53. Snout 
1? to 24 as long as diameter of eye, which is 43 to 54 in length of head ; 
interorbital width 4 to 5. Lips fringed and papillose; barbel reaching 
margin of upper lip. Gill rakers, 12 to 15 in lower anterior arch. 
Dorsal 11 to 12 ; first ray three-fifths of second, which is about two-fifths 
length of fourth; fourth and fifth rays the longest, 12 to 2 in length of head.
