118 GOBIES OF THE PHILIPPINES 



Genus 27. CHLAMYDES Jenkins 



Chlamydes JENKINS, Bull. U. S. Fish Comm. 22 (1903) 503. 



This genus agrees with Gobius except for the presence of scales 

 on the sides of the head, the opercles and preopercles being 

 more or less completely scaled, and in the tongue being de- 

 cidedly notched. The cheeks are full and rounded, the teeth 

 in bands in each jaw, with the outer series in the upper jaw 

 enlarged; the ventrals are short, very broad, with a thick bi- 

 lobed frenum, forming a sucking disk like that of the gobies of 

 mountain torrents. 



Previously known from a single specimen captured at Hono- 

 lulu by Dr. O. P. Jenkins. 



49. CHLAMYDES LEYTENSIS sp. HOT. 



PLATE 8, FIG. 3 



Dorsal VI, 1-8 or 9 ; anal I, 7 or 8 ; there are 36 to 38 scales 

 in a longitudinal series, 13 or 14 in a transverse series, and 

 about 22 before the first dorsal. 



The body wedge-shaped, narrowed dorsally and broader below, 

 the sides of posterior half strongly compressed, the dorsal and 

 ventral profiles nearly parallel, the depth 4.5 to 4.9 times in 

 length; the large, broad, rather depressed head 2.75 to 3.1 times 

 in length; the cheeks full, the width of head 0.7 to 0.85 of its 

 length and about a half more than its depth ; the snout broadly 

 rounded, slightly convex, 3.5 to 4 times in head, and a little 

 more than eyes, which are almost on top of head, dorsolateral, 

 4 to 4.25 times in head; the postorbital portion of head equals 

 or slightly exceeds distance from snout to posterior margin of 

 eye; the interorbital region is ^ or an eye diameter; the 

 mouth terminal, with very thick, fleshy lips, fringed within, 

 slightly oblique, the posterior angle of maxillary beneath middle 

 of pupil; the outer row of rigid teeth in upper jaw much en- 

 larged, followed by a band of three rows of fine depressible 

 teeth, the inner teeth larger than those of the other two; the 

 lower jaw has a band of three or four rows; anteriorly the 

 outer and inner rows enlarged ; posteriorly the inner row much 

 the largest, though not as large as the outer row in upper 

 jaw ; in one specimen there is a pair of small lateral canines in 

 lower jaw ; the scales before first dorsal are much smaller than 

 those on sides of body and extend forward to eyes, from which 

 they are separated by a mucus channel; the opercles covered 

 on upper half by tiny scales, which also may occur on upper
