V. — A Collection of Fishes from Lagos. 

 By C. TateKegan, M.A. 



(Published b}' permission of the Trustees of the British Museum.) 



The collection here reported on has been made and presented 

 to the British Museum by Mr. J. Cadmaii, of tlie Western 

 Fisheries, Ltd. The majority of tlie fislies were trawled oft" 

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

 the case for the seven species described below as new. Some 

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

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

 there is a ceitain proportion of species found so tar 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 ofricana, 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 whetiier either of the Medi- 

 terranean species of Squaiina occurs at Lagos. 



2. Rhynchohatus ailanticus, sp. n. 



Very similar in form, structure, and coloration to the 

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

 originating behind base of pelvics ; distance from end of 

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

 space between dorsals. Spines stronger and fewer, similarly 

 distributed except for the presence of a series on each side 

 of the rostral cartilage and the absence of a median series
