AMBLYGOBIUS 231 



the pectoral equals depth ; the ventral short, 1.36 times in depth, 

 its tip lacking six scales of reaching the short blunt anal papilla. 

 The color in alcohol dusky brownish above, very pale below; 

 a narrow, dark brown band runs around snout on upper lip 

 to eye, and from its posterior margin continues on back to 

 upper part of base of caudal, the posterior part very faint; a 

 similar band encircles chin, goes from corner of mouth across 

 preopercle and opercle to base of pectoral, where it apparently 

 stops, but really continues beneath pectoral back along middle 

 of side to a large, circular, blackish brown spot on base of 

 caudal; five wide blackish bands with indefinite margins cross 

 back and descend on sides, thus forming six oblong whitish spots 

 along middle of side, between the two longitudinal bands; each 

 scale on back and side has a more or less evident, small, central 

 whitish spot, these spots forming longitudinal rows; the top of 

 snout dark brown; the dorsals and anal brownish, the mem- 

 branes faintly specked with minute brown dots; the other fins 

 without distinctive markings.

PLATE 18, FIG. 4 



Dorsal VI, 1-13; anal I, 12; there are 60 scales in a longitu- 

 dinal series and 16 in a transverse series. 



The slender wedge-shaped body less elevated than in our other 

 species of Amblygobhis, its depth 4.7 times in length ; the head 

 broader than trunk, and contained 3.7 times in length ; the short, 

 blunt, convex snout equals eye and is contained 3.5 times in 

 head; the distance from tip of snout to posterior margin of 

 eye equals postorbital length of head; the breadth of the in- 

 terorbital space 0.75 that of snout or eye; the mouth strongly 

 oblique, the posterior angle of maxillary extending beneath cen- 

 ter of eye; the pores on head typical of the genus; the nape 

 covered with scales smaller than those on sides and there is a 

 small patch of tiny scales along forward part of upper margin 

 of opercle; the depth of caudal peduncle 1.25 times in its length; 

 the pectorals equal head and are longer than the ventrals, which 

 are about 0.7 of the distance from their origin to anus; the 

 caudal exceeds head in length; the fifth dorsal spine most 

 elongated, its length more than the greatest depth of body; the 

 second dorsal and anal similar in outline, their posterior rays 

 extending upon caudal when depressed and much longer than 

 depth of body beneath them.
