BATHYGOBIUS HI 



the teeth in several rows in jaws, the external row much larger 

 than the inner rows in upper jaw, those of lower jaw scarcely 

 larger, no canines or caninelike teeth; the mouth slightly ob- 

 lique ; the oculoscapular groove conspicuous ; the head and nape, 

 back to first dorsal, entirely naked; about 22 large scales in a 

 longitudinal series; anal appendage oblong conical; the dorsals 

 basally approximate, the highest dorsal spines flexible, produced 

 anteriorly, scarcely higher than body; the soft dorsal obtuse, 

 angulate posteriorly, the first ray flexible ; the pectorals rounded, 

 the upper rays threadlike, 5* or less, the ventrals 6, the obtusely 

 rounded caudal about 3.8 in length of body; the anal not lower 

 than second dorsal, angulate posteriorly. 



The color of body dilute green, with a violet-black band from 

 eye to operculum; a few violet-green spots on head and body, 

 those on sides large to medium, about nine, oblong, irregularly 

 transverse, and disposed in longitudinal series; the second dor- 

 sal dilute violet, the apex becoming yellow, with two or three 

 longitudinal black stripes; the other fins yellowish, the dorsal 

 and caudal rays spotted with violet; the ventrals violaceous in 

 the middle. 



The above is a translation of Bleeker's original description. 

 It is given here because specimens collected by Jagor at Tibi, 

 Albay Province, Luzon, were determined by Peters as this 

 species. 



According to Giinther it inhabits the coasts and rivers of 

 Java, Madura, and Sumatra. 



Genus 26. BATHYGOBIUS Bleeker 



Bathygobius BLEEKER, Arch. Neerl. Sci. Nat. 13 (1878) 58. 

 Mapo SMITT, Ofv. Vet. Ak. Vorh. (1899) 543. 



Dorsal VI, 1-8 to 10; anal I, 7 to 8; scales in a longitudinal 

 series 35 to 42 ; the nape is always more or less scaled. 



This genus agrees in most respects with Gobius, but the 

 tongue is more or less notched, instead of having the tip rounded. 

 In Bathygobius the tongue is not of uniform thickness, but the 

 central part of the tip seems as though it had been mortised 

 out and is much thinner than the sides, so that these not only 

 rise higher but seem to project farther forward than they 

 actually do. When seen from below, as in opening the mouth, 

 ordinarily, the tongue appears to be strongly notched. When 

 viewed from above and the tip flattened, it is seen to be more 

 or less notched, or subtruncate with indented tip. The scales 

 are a little smaller than in Gobius.
