AMBLYGOBIUS 237 



base of tail very narrow; on the first three the black marginal 

 lines extend only halfway down; the lower half of each of the 

 crossbands, except the fifth, bordered on each side by a wide, 

 pearly white band; on upper half of body these pearly bands 

 are continued as two pearly white spots; a dark blue band on 

 tip of snout from eye to eye; a wide blue band from angle of 

 mouth diagonally upward across preopercle and opercle, and 

 forming a horizontal bar on base of pectoral; between it and 

 eye a broad, pearly white band upward and backward to base 

 of pectoral, and a similar band below it and extending upon 

 base of pectoral; a dark blotch behind eye and another at up- 

 per posterior angle of opercle; the fins marked approximately 

 as in the Sitankai specimen. This specimen lacks the red spots 

 on nape, but agrees in essentials with A. phalaena. 



Other Philippine localities are Cagayancillo, recorded by Jor- 

 dan and Richardson, and Samal Island in Davao Gulf, where 

 it was obtained by Scale. 



I collected, on September 15, 1925, eleven specimens at Cebu, 

 65 to 108 millimeters long. They are all big-headed, thick, 

 robust fishes ; the largest two are spawning females, their depth 

 3 and 3.5 times in the length. I received seven more from 

 Tagbilaran, Bohol. 



This very handsome goby occurs only in the sea. It was first 

 collected at Vanikolo, and occurs throughout the East Indies and 

 from the Pelew to the Samoan and Society Islands.

Dorsal VI, 1-14; anal I, 14; there are 52 to 54 scales in a 

 longitudinal series and 20 in a transverse series. 



The body oblong, compressed, with convex anterior profile, 

 the depth equal to head and about 3.4 in length ; the short snout 

 is 3.45 to 3.6 in head and equals or very little exceeds eye, 

 which is 3.6 to 3.8 in head ; the interorbital space 4.4 to 4.7 in 

 head; the mouth rather large, strongly oblique, the angle of 

 maxillary reaching a point beneath front margin of pupil; the 

 teeth larger and more prominent than in A. phalaena; the pores 

 on head present as in A. bynoensis and A. phalaena, but they
