It is thus apparent that the Macrouroid fauna most nearly related 

 to that of the East Indies and the Philippine Islands is the fauna 

 of Japan, which is probably largely derived from the southward. 1 

 These two faunas contain the largest number of species common to 

 both, and they contain the largest number of geminate species; but 

 this is not the only reason for considering them more closely related 

 to each other than either is to any other known fauna. As corrobo- 

 rative evidence we may note that the Coelorhynchus notatus group 

 of species from the Philippines and East Indies finds its only close 

 relatives in C. jordani and C. kishinouyei of Japan, and that the re- 

 markable subfamily Macrouroidinae is represented by but two 

 species : Macrouroides inflaticeps of eastern Luzon and Squalogadus 

 modiflcatus of Japan. In addition to Macrouroides and Squaloga- 

 dus, there is but one genus not common to both regions, no repre- 

 sentative of Maiaeocephalus being yet known from Japan. 



2. ANALYSIS OF THE EAST INDIAN-PHILIPPINE FAUNA. 



The fauna of Macrouroid fishes in the East Indian and Philippine 

 Islands has been compared with the faunas of other regions, and 

 found to resemble that of Japan most closely. In order to determine 

 the subdivisions of the fauna of the Philippines a distributional 



1 Excluding, of course, the three subarctic species reaching northern Japan (Coryphac- 

 voides pectoralis, C. acrolepis, and C. cinereus).
