This species is known from a smgle young spechncu, obtained by^ 

 Dr. E. Hartert at Brass, mouth of the Niger. It occupies a perfectly 

 isolated position in the genus, and I have therefore proposed to make 

 it the type of a section, under the name of Teenier emias, of which a 

 definition is given above, p. 228.
