PHILIPPINE MACROUROID FISHES GILBERT AND HUBBS. 375 



Distributional lists of the species — Continued. 



1 Known only from depths greater than 700 fathoms; owing to the paucity of dredge hauls at such depths 

 these records may have little significance; the same is true, to a somewhat lesser degree, of the distribu- 

 tion of Matacocephalus adustus and Cetonurus robustus. 



2 From western Luzon. 



3 From Palawan Passage. 



A. THE EAST INDIAN SUBREGION. y 



The East Indian subregion alone contains species supposed to be 

 identical with those of the Indian Ocean. Many of its species occur 

 also in the Philippine subregion, and three are found in Japan — 

 namely, Gadomus multifilis, Trachonurtis villosus, and Cetonurus 

 robustus; in addition to these there occurs in the East Indian sub- 

 region a species identical or closely allied with Coelorhynchus paralle- 

 lus of eastern Luzon and Japan. Gadomus multifilis was also 

 dredged off eastern Luzon, but Cetonurus robustus was not obtained 

 in intermediate localities. Of these four species Trachonurus villosus 

 is the only one known from the Philippine subregion; the other 

 three East Indian forms, found also in Japan, if now connected with 

 the Japanese population of their species, are probably so connected
