This species has sometimes been united with 

 P. bclcheri, Bennett, from West Africa, but an examina- 

 tion of specimens from both localities shows that the 

 two are distinct. The principal differences are as 

 f olloAvs : 



I. Depth of body 2J to 2 in the length, length of head 3i to 

 3; lower jaw 3j to 4 in length of body; 24 to 28 scales in 

 a transverse series between lateral line and middle of 

 back, 34 to 38 round caudal peduncle; caudal fin without 



dark spots 1. erumei. 



II. Depth of body 2 to 2 in the length, length of head 3i to 3|; 

 lower jaw 4 to 5 in length of body; 21 to 22 scales in a 

 transverse series between lateral line and middle of back, 

 29 to 30 round caudal peduncle; caudal fin with vertical 

 rows of large dark spots 2. belcheri
