196 GOBIES OF THE PHILIPPINES 



of caudal in a conspicuous elliptical spot ; there is a black spot at 

 top of membrane between first and second dorsal spines, the rest 

 of the fin specked with black ; the second dorsal and caudal cross- 

 barred by several rows of faint blackish spots; the other fins 

 colorless. 



Here described from a specimen, 34 millimeters long, collected 

 at Canigaran, near Puerto Princesa, Palawan, by R. C. Mc- 

 Gregor. 



In life this delicate little fish is translucent, with spots of 

 dark orange and pure black. Our specimen is almost an exact 

 duplicate of the one figured by Jordan and Seale. 



I have since discovered three specimens of this species in the 

 Bureau of Science collection. They were collected by Alvin Seale 

 at Puerto Galera, Mindoro, in 1912, and are in very bad condi- 

 tion, the scales almost entirely gone. They are all of the same 

 length, 40 millimeters. 



This unique, easily recognized dwarf goby has been recorded 

 previously from Ponape of the Caroline Islands, and from the 

 Samoan and the Society Islands. 



Genus 37. PANDAKA g. nov. 



The minute gobies placed under this title are distinguished 

 by their teeth and fins. There are two rows of very small, 

 slender, pointed teeth in each jaw, or the upper jaw may have 

 three rows, the outer row in upper jaw larger and more widely 

 spaced, the inner row excessively minute; the two rows in lower 

 jaw of approximately equal size; the first dorsal short, well in 

 advance of second, the anterior rays highest; the second dorsal 

 and anal are both short and lower than first dorsal. Dorsal VI, 

 1-6 or 7; anal I, 5. The body covered with large, firm ctenoid 

 scales, about 22 in longitudinal series, the head and nape naked 

 back to origin of first dorsal ; the caudal round pointed, shorter 

 than head; the gill openings restricted, the isthmus broad, the 

 branchiostegals 5. Generic type, P. pusiUa, sp. nov.

Key to the species of Pandaka.

a*. First spine of dorsal not elevated, 1.25 times in depth; body much 

 slenderer, depth 4 to 4.8 in length in females, 5 to 5.6 in males; length
