PHILIPPINE MACROUROID FISHES GILBERT AND HUBBS. 563 



We have tabulated the measurements of "this species while com- 

 paring it with Lionurus cetonuropsis, its Japanese representative. 

 (parvipes, in reference to the reduced ventrals.) 



Genus MATAEOCEPHALUS Berg. 



This genus is not intermediate between Macrourus and Coelo- 

 rhynchus as Radcliffe x has suggested. It is really related to Lion- 

 urus in a manner analogous to that by which C oelorhynchus is re- 

 lated to Coryphaenoides (Macrourus). The similarity between the 

 two genera, consisting in the production of the snout and in the 

 correlated strengthening of the infraorbital ridge, is due to con- 

 vergence rather than to common origin.

Type 



This species seems to be distinct from Mataeocephalus micros tomus 

 (Regan) , the only one with which it might be confused.
