"SCOTIA" COLLECTION OF ATLANTIC FISHES. 387 



V. FISHES COLLECTED AT ST HELENA. 



(MS. received 13th January 1913. Read 24th February 1913. Issued separately, 30W /n*1913.) 



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 in the fish fauna of the island. 



These are 



Gonorhynchus greyi. 



Exoccetus speculiger. 

 Thynnus pelamys. 

 Sargus rondeletii. 



Little importance can be attached to the occurrence of Exoccetus 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 Eegan, 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 greyi and Synodus synodus. 



Gonorhynchus greyi (Richardson). 



Depth of body 7| to 10 in the length ; length of head 4f to 5^. Snout 

 If to 24 as long as diameter of eye, which is 4^ to 5^ 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, 1| to 2 in length of head.
