PHILIPPINE MACROUROID FISHES GILBERT AND HUBBS. 417 



7. The interdorsal space appears to be shorter, 1.0 to 1.25, instead of 1.3 

 to 2.3, times as long as the first dorsal base. 



8. The ventral filament is weaker, and shorter. 



9. The color, especially of the fins, is a little lighter. 



The slight difference in size between our specimens of the two 

 species renders wholly improbable any assumption that these dif- 

 ferences may be due to age variation. Furthermore, the dorsal spine 

 usually decreases in length with age in the species of this long-spined 

 group, and such appears to be the case with C. tydemani, but C. 

 semiscaber, though represented by smaller specimens, has a much 

 shorter spine.

Brauer considers C. lophotes to be the young of C. macrolophus, 

 a conclusion which is apparently justified. But inasmuch as Brauer 

 states that most of his specimens have seven branchiostegal rays, it 

 is highly probable that he had, in part at least, a species of another 

 genus, as all specimens of Coryphaenoides examined by us have 

 constantly six branchiostegal rays. 



C. macrolophus is not represented in the Philippine collection. 

 Radcliffe's x reference to Philippine specimens should apply to C. 

 semiscaber and to C. tydemani.
