70 MORMYROPS HENRYI. 



The adipose fin appears to be a little more developed 

 than in K. adansonii. 



Only one specimen ol this species was captured: in a 

 specimen of E. adansonii of about the same size there was 

 no trace either of bands or punctuation.

This species was hitherto only known from a descrip- 

 tion of Gill based upon a specimen in the Philadelphia 

 Museum. He made it the type of a new genus Isichthys , 

 which has afterwards been united with Mormyrops by 

 Günther. The locaHty from whence this specimen had 

 come could however no more be traced, although Gill 

 states that he is disposed to believe that it was collec- 

 ted in Liberia (Proc. Ac. Nat. Sc. Philad. 1862, p. 444). 

 This suggestion is now confirmed by the second specimen 

 on record which has indeed been captured in the St Paul's 

 river by our travellers.
