Sternachus albifrons (Linnaeus). Peruvian Am- 

 azon. A young one from the Ambyiacu River also 

 likely this species. 



Sternarchus bonapartii Castelnau. Peruvian 

 Amazon. 



Sternarchella balaenops (Cope). This is only 

 known from the type (Sternarchus balaenops Cope, 

 Proc. Amer. Philos. Soc., 1878, p. 682) from the 

 Peruvian Amazon. It is closely related to Sternar- 

 chella schotti (Steindachner) , but differs chiefly in 

 its shorter head and the more swollen protruding 

 mandible.

EUROPEAN AND AMERICAN HADDOCK. 



In the effort to determine any racial differences, 

 if such exist, between European and American Had- 

 dock (Melanogrammus aeglifinis), a vertebral count 

 of 25 examples of the latter was recently made at the 

 U. S. Bureau of Fisheries. The comparisons were 

 made with published records of the vertebral count 

 of haddock from Scotland and Iceland (Williamson, 

 26th Annual Report of the Fishery Board for Scot- 

 land). The results as indicated below, show that 

 there is no appreciable difference in the number of 

 vertebras between fish from the several localities.
