 diameter. 



Hinagianan River, Camarines

San Jose, Leyte, 2. 



Without locality label, 15 fine 

 specimens. 



Three of the specimens from Irid River, Rizal Province, have 

 but five spines in the first dorsal ; in several of them the second 

 and third spines are greatly elongated, reaching beyond the 

 origin of the second dorsal when depressed. 



Genus 29. GNATHOLEPIS Bleeker 



Gnatholepis BLEEKER, Arch. Neerl. Sci. Nat. 9 (1874) 318; JORDAN and 



SEALE, Bull. Bur. Fisheries 25 (1906) 394. 



Hazeus JORDAN and SNYDER, Proc. U. S. Nat. Mus. 24 (1901) 51. 

 Exyrias JORDAN and SEALE, Fishes Samoa, Bull. Bur. Fisheries 25 



(1906) 405. 



This genus is separated from all other small, slender gobies 

 without silky rays on the pectoral by having the cheeks en- 

 tirely and the opercles partly or entirely covered with large 

 scales. The dorsals are close together, not elevated, VI, 1-8 

 to 11; anal I, 8 to 11; the scales are moderately large, 24 to 

 32 in a longitudinal series ; the head is convex, the mouth oblique, 

 the tongue notched in our species, except in the subgenus 

 Exyrias, the body laterally compressed and moderately elongate ; 

 the caudal is rounded, shorter or longer than the head; the 

 teeth are in two to four rows in each jaw, fixed or depressible, 

 those of the outer row enlarged; a posterior canine may be 

 present in the lower jaw; exceptionally canines may be present 

 in the upper jaw in front of the other teeth; the gill opening 

 is of moderate width, not extended forward, the isthmus broad ; 

 no silky rays above on the pectoral. 



Exyrias does not seem to me to be a well-founded genus, 

 though it might be considered a subgenus, separated by having 

 two conspicuous longitudinal grooves on the preopercle ; the tip 

 of the tongue is rounded, while in other Philippine species of 

 Gnatholepis it is notched. Some species of Gnatholepis else- 

 where are said to have it rounded.
