V. — A Colled ion of Fishes from Lagos. 

 By (J. Tate JlEGAN, M.A. 



(Published by permission of the Trustees of the Dritish Museum.) 



The collection here reported on has been made and presented 

 to the British Museum by Mr. J. Cadinau, of the Western 

 Fisheries, Ltd. Tlie majority of the fishes were trawled off 

 Lagos at a depth of 10 to 35 fathoms, and this was certainly 

 the case for the seven sj)ecies described below as new. Some 

 o£ the coast-fishes of West Africa are identical with those 

 of tiie Mediterranean, others are known from the Cape, and 

 there is a ceitain proportion of species found so far away 

 as the coast of Brazil and the Indian Ocean ; to illustrate 

 this the known distribution of the species, other than those 

 restricted to West Africa, is given. 



1. Squaiina africana, Regan. 

 Ann. Natal Mus. i. pt. 3, 1908, p. 248, pi. xxxviii. 



This species was originally described from Natal ; it 

 would be of interest to ascertain whether either of the Medi- 

 terranean species of Squaiina occurs at Lagos. 



2. RhijnchoJiatus atJanticus, sp. n. 



Very similar in form, structure, and coloration to the 

 Indian U. djeddensis, Forsk. First dorsal fin farther back, 

 originating behind base of pelvics ; distance from end of 

 snout to origin of first dorsal more than four times the inter- 

 space between dorsals. S|)ines stronger and fewer, similarly 

 distributed except for the presence of a scries on each side 

 of the rostral cartilage and the absence of a median scries
