EUTROPIUS LIBERIENSIS. 69 



head is finely granular. The maxillary barbel, when not 

 mutilated, reaches as far as the end of the pectoral, the 

 nasal barbel as far as the posterior border of the occipi- 

 tal fontanel. 



The colour in life is dark green with a small number of 

 minute yellow dots placed in more or less regular trans- 

 verse rows. 



The vernacular name is Soa. 



Malapterwrus electfivus. 



This fish rarely exceeds one foot in length and is more 

 common in the small creeks communicating with the St. 

 Paul's river than in the river itself. About thirty speci- 

 mens were collected ; even of the small specimens the shocks 

 can be very painfully felt. 



Vernacular name: Dobho. 



JEutropiug adansonii. 



This species, the vernacular uame of which is i^acZa, ap- 

 pears to be only caught at twilight. 



Eutropiws Hberiensis n. sp. ^ 



Closely allied to the foregoing species from which it 

 differs both in the coloration and in the number of rays 

 in the anal fin. Steindachner has fixed this number for 

 E. adansonii at from 56 to 58 , whereas in E. liberiensis 

 there are only 50 rays. The formula for the dorsal and 

 pectoral fins is D. ^/g; P. ^/jq. 



There are four dark longitudinal bands, one along the 

 back, one above and one below the lateral line, the two 

 latter only separated by a narrow silvery interspace, one 

 from the pectoral to the caudal. The whole surface of the 

 body is covered with minute dark dots which stand closer 

 together along the dark longitudinal bands. There is a 

 faint black blotch above the pectoral. The exterior border 

 of the anal is not black as in L. adansonii but lighter than 

 the inner half.
