PHILIPPINE MACROUROID FISHES GILBERT AND HUBBS. 545 



a*. A conspicuous pearly body in a sheath between the ventrals ; mouth notably 

 oblique, spinules on scales arranged in quincunx order (Lucigadus, new 

 subgenus) hicifer. 



Three species, atherodon, nigromarginata, and lucifer are sharply 

 distinguished from the others, and may serve as the respective types 

 of the new subgenera Atherodus, LucigadeUa, and Lucigadus. 



(Vent?*ifossa, in reference to the scaleless fossa present in the typical 

 species between the ventral fins.) 



Subgenus Ventrifossa Gilbert and Hubbs.

Type. 



This species is related most closely to V. misakia, of Japan and* the 

 east coast of Luzon.

1914, p. 306, pi. 38, fig. 2 (not Coryphaenoides asjw Giinther). 



A single specimen of this well-marked species, hitherto known only 

 from Japan, was collected during the Philippine cruise ; it was 

 dredged at Albatross station 5445, off the southeastern coast of 

 Luzon ; depth, 383 fathoms ; bottom temperature. 44.3° F. 



Dorsal rays, II, 10; ventral rays, 8. 



We compare this specimen in the following table with two, includ- 

 ing the type, from Japan. Certain differences are indicated which 

 render somewhat doubtful the reference of our specimen to V. 

 m isakia. The snout is longer ; the barbel much longer ; the distances 

 greater between the anus and the origin of the anal fin and between 

 the ventral base and the isthmus.
