FIG. 110. Synodontis macrostigma. Younger specimen from the Kafue River. 



Colour (of preserved specimen), brown, darker above than beneath ; 

 back and sides with large, oval, dark spots in irregular lines ; head 

 and fins with small dark spots. 



One specimen, 125 mm. in length, from Kafue Eiver, tributary of 

 the Zambezi (J. Drury). 



This fish, for the determination of which we are indebted to Mr. 

 Boulenger, closely resembles his S. macrostigma, but the eye is much 

 larger proportionately, the spots are fewer and larger, as shown in 

 Fig. 110, and there are other minor differences.
