320 GOBIES OF THE PHILIPPINES 



Genus 69. PERIOPHTHALMODON Bleeker 



Periophthalmodon BLEEKER, Arch. Neerl. Sci. Nat. 9 (1874) 326. 



The teeth in upper jaw in two rows, the outer one with ca- 

 nines present anteriorly, the inner row sometimes wanting; in 

 lower jaw there is a single row, of which part may be canines ; 

 the pharyngeal teeth in few rows, most of them strong and coni- 

 cal. The ventrals united in adults, separate in the young; the 

 first dorsal exceedingly variable, spines to XV, second dorsal 

 I, 11 or 12 ; the pectorals have an exceedingly thick, long, mus- 

 cular base, the fin scaled for more than half its length ; the scales 

 are moderate, 48 to 60 in a longitudinal series, cycloid, not 

 smaller anteriorly except on the sides of head and on snout. 



Jordan, in his work on the genera of fishes, states that Pe- 

 riophthalmodon is a synonym of Periophthalmus, as restricted 

 by Gill. As I am unable to get a copy of Gill's paper, I have 

 followed what seems to me to be Schneider's arrangement, 

 as restricted by Bleeker, vide Bloch and Schneider, Systema 

 Ichthyologica.

Poiss. 12 (1837) 148. 



Dorsal 0, XV, 1 to 12 ; anal 1, 12 ; there are 48 to 60 scales in a 

 longitudinal series and 16 to 20 in a transverse series. 



The variety named P. freycineti by Valenciennes is most- 

 characteristic of this species in the Philippines and is repre- 

 sented in the Bureau of Science collection by a fine male spec- 

 imen, 101 millimeters long, collected at Iloilo; it has 4 dorsal 

 spines, the base of the first dorsal very short, scales in longitu- 

 dinal series 49, in transverse 16. The following description is 

 based upon this specimen : 



Body plump, laterally compressed, the depth 5.3 times in 

 length; the subcylindrical head somewhat flattened dorsally, 3.8 

 times in length, its breadth equal to depth of body and slightly 

 more than its own depth, 1.6 times' in its own length; the con- 

 vex snout nearly vertical anteriorly, bluntly rounded, 2.6 times 

 in head and twice the prominent, stalked, erectile eyes; the
