BULLETIN 100, UNITED STATES NATIONAL MUSEUM. 



table has been drown up, in which the number of specimens of each 

 species dredged by the Albatross is given for eight different regions; 

 in addition the six or seven species * dredged in the East Indies only 

 by the Siboga are marked by a cross (X) in the column for that 

 region. No attempt is made to define the subdivisions in the East 

 Indies for the Macrouroid fauna. 



Ten columns are used, corresponding to the following regions : 



1. Known also from the Indian fauna. 



2. East Indian subregion. 



3. Tawi Tawi (or Sulu) Archipelago, and the Gulf of Davao, 

 southern Mindanao. 



4. Philippine subregion (q. v.). 



5. Eastern Mindanao. 



6. Eastern Luzon. 



7. Northern and northwestern Luzon. 



8. Formosa. 



9. Off Hongkong, China. 

 10. Known also from Japan. 



Distributional lists of the species. 



1 Possibly one or two others should be included. 



- 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 

 distribution of Matacocephalus adustus and Cetonurus robustus.
