202 GOBIES OF THE PHILIPPINES 



interorbital space less than width of pupil; the mouth oblique 

 at an angle of about 45, the lower jaw projecting, the posterior 

 angle of maxillary under front margin of eye ; the outer row in 

 upper jaw has enlarged, curved, widely spaced teeth, followed 

 by two rows of very small teeth, the middle ones of inner row 

 enlarged; the lower jaw has two rows, the outer one enlarged; 

 the dorsal spines slender, the second one longest, 2.25 times in 

 head, none reaching second dorsal when depressed; the second 

 dorsal and anal longest posteriorly, not reaching caudal when 

 depressed, higher than first dorsal, the longest dorsal ray 1.75 

 times in head, the anal a little lower, its longest ray 1.85 in 

 head; the caudal peduncle depth 2.5 times in head; the rounded 

 caudal 1.25 times in head; the pectorals round-pointed, a trifle 

 shorter than head; the ventrals 1.1 in head, not reaching the 

 short, thick, rounded anal papilla. 



Color dark brown banded by 12 narrow white, dark-margined vertical 

 bands which completely encircle the body and are of much less width than 

 the interspaces; four of these bands are on the head, the first over the 

 snout just in front of eyes and down to angle of mouth, the second from 

 outer part of nuchal region down through eyes, the third and fourth from 

 nuchal region down sides of head, the fifth from origin of dorsal over 

 base of pectorals, the remainder at regular intervals on body, there being 

 one around the middle of caudal peduncle and another at base of caudal; 

 these last two indistincc. Vertical fins uniform dark grayish, pectorals 

 and ventrals yellowish white. [Seale.] 



The type and sole specimen is No. 5505 of the Bureau of 

 Science collection, obtained by Alvin Scale at Puerto Princesa, 

 Palawan. Its length is 35 millimeters. It is now badly dam- 

 aged, most of the fins are broken, and the white bands much 

 faded. It must have been very handsome in life. 



So far as I am aware, no such genus as Pleurogobius has ever 

 been published, and it is not recognized by Jordan in his work 

 on the genera of fishes. In the Bureau of Science accession 

 book the specimen was cataloged under the name of Pterogobius, 

 but from that genus it is far removed. 



Genus 40. ABOMA Jordan and Starks 



Aboma JORDAN and STARKS, Proc. Calif. Acad. Sci. II 5 (1895) 497. 

 This genus is distinguished by the presence of seven or eight 

 dorsal spines ; the head is naked, rounded in profile, narrow, not 

 depressed between the eyes; the mouth moderate, not very 

 oblique, the chin not very prominent, the tip of tongue not 

 notched, the outer teeth somewhat enlarged; dorsals and anal
