GLOSSOGOBIUS 161 



de Bay, Rizal Province, were full of eggs and ready for spawn- 

 ing. It spawns in October and November in the region near 

 Manila. Glossogobius celebius takes the hook eagerly, and I 

 have seen old men and women catch large strings of this species 

 in the mountain streams of Nueva Vizcaya. It is one of the 

 important ipon fishes. The Bureau of Science collection con- 

 tains ninety-two specimens of ipon, 20 to 30 millimeters in 

 length, collected by E. A. Mearns "3 miles up the Laoag River," 

 which belong here. 



This species is readily distinguished from other members of 

 the genus by the eyes, by the number of scales before the first 

 dorsal, and by the distance from the tip of the snout to the rear 

 margin of the eye being greater than the remaining length of 

 the head. Specimens with the papillae greatly developed on the 

 head and with very fat cheeks present a very different appear- 

 ance from the general run of the species, and only the presence 

 of intermediary stages enables one to determine them as G. 

 celebius. The Tagalog fishermen of Lake Taal differentiate this 

 species from G. giurus without hesitation. 



Originally described from Celebes, it has also been recorded 

 from Nias, Amboina, Timor, Flores, New Guinea, and the Aru 

 Islands. 



Although Steindachner's description of Gobius pavo omits 

 some characters used in my diagnosis, I have no hesitancy in 

 pronouncing his specimen an example of G. celebius.
