406 BULLETIN OF THE BUREAU OF FISHERIES. 



This handsome species is rather common on the soft bottom behind the coral reefs of Apia. It is 

 closely related to Amblygobius bynoensis, the genus being characterized by the presence of rather strong 

 canines on the side of the jaw. Scales small, covering top of head, and extending on operc.le above; 

 pectorals with no silk-like rays; dorsal vi, 15; anal 14. 



Life colors of a specimen from Apia, dark olive; 5 dark brown bands, each edged on both sides 

 with light blue, the bands broader than the grayer interspaces; from middle of each brown band a 

 narrower bar crosses the back; head with many oblong and round sky-blue spots darker than the 

 interspaces; 2 rows of orange spots on each side of nape; a round black shoulder spot; some bluish 

 oblong dashes on front of side; first dorsal olive, with a black central blotch and a black edge; second 

 dorsal mottled gray, then edged with light yellow, black and brown; caudal brownish, dusky behind; 

 a black ocellus near base above; anal grayish with a row of whitish spots at base and a black edge; 

 ventral black, paler centrally; pectoral bright golden yellow, with a blue horizontal streak and 2 blue 

 spots at base. Body compressed, the scales rather small. 



Another specimen, male, has 4 plain black cross-bars and 5 ocelli on caudal irregularly placed; 

 the black margin broader, the dorsal with 2 rows of bluish dots, the anal wdth a bluish streak. 



A third specimen from this locality was olive-green with round spots of grayish blue on head 

 surrounded by dark blue streak; first dorsal olive with a black spot; second dorsal olivaceous mottled 

 with dark brown; caudal light brownish with 2 black spots; a black spot above gill-opening; lower 

 fins pale. 



Seven specimens from Apia. 



1473. Arnblyg-obius papuanus (Peters). New Guinea. 



Gobius papuanus Peters, Berl. Mon. 187(3, 839, New Guinea. 



1474. Amblygobius sphinx (Cuvier & Valenciennes). New Guinea; East Indies. 

 A very robust species with black cross-bands. 



CRYPTOCENTEUS Ehrenberg. 



Cryptocentrus (Ehrenberg) Bleeker, Arch. Neerl. 1875, 322 (cryptocentrus). 

 This genus, as understood by us, comprises species allied to RItinogobius but covered with small 

 scales, instead of large ones. 



1475. Cryptocentrus leucostictus (Giinther). Tonga. 



Gobius leucostictus Giinther, Proc. Zool. Soo. 1871, 664, Tonga. Giinther, Fische der Siidsee, 176, Tonga. 

 This species, which we have not seen, seems to belong near Cryptocentrus. 



VITEARIA Jordan & Evermann. 



1476. Vitraria clarescens Jordan & Evermann. Haw 7 aii. 



PSELAPHIAS Jordan & Seale, new genns. 

 Pselaplnas Jordan & Seale, new genus of Gobiidse ( Gobius oj>hthahaonemus) . 



This genus is close to Gobionellus (liastatus) , and still closer to Oxyurichlhys (belosso), differing from 

 both in the presence of a tentacle above the eye. 



1477. Pselaphias ophthalmonemus (Bleeker). Samoa; Fiji; Akyab; East Indies. 



Gobius ophthalmonema Bleeker, Nat. Tijds. Ned. Ind. 1856, xn, 208. 



Euctenogobius ophthalmonemus, Giinther, Fische der Siidsee, 180, taf. Ill, fig. B, Tonga, Fiji, Akyab. 



Life colors of an Apia specimen, a black bar below eye; dull olive with quadrate and other blotches 

 along side; back mottled; no pale spots; no bright colors; fins much, mottled; dorsal with a black 

 blotch on last rays. 



Three specimens from a sluggish bayou of Vaisigano River at Apia. Dorsal filamentous.
