STERNARCHORHYNCHUS MORMYRUS ( Steindachner.) 



In the gene nil contour of the head these specimens agree with A'. 

 cunurostrls Boulenger, but in the shape of tlie snout thev agree more 

 nearh' with aV. )norinyrus Steindachner; in the number of anal ra3^s 

 (101-11*4) the specimens are intermediate between the two species. We 

 are inclined to think, therefore, that cHrr/i'ostrls will prove identical 

 with inonni/riis.
