394 BULLETIN OF THK BUREAU OF FISHERIES. 



Of tluH species we have 8 specimens fnnii Ana, mi the imrth slmrc "f Tiituila, 9 from Pago Pago, 

 50 from mouth of Vaipigono River at Apia, ami 1 fri>m Apia collecttMl by Dr. Lung, U. S. N., in 1890. 



This extraordinary little fish is very abundant in the sluggish and brackish waters in the mouths 

 of the streams of Samoa. It abounds especially in muddy bayous, freely leaving the water to climb 

 bushes, to skip through the grass or to lurk under piles of stones to await the returning tide. It is 

 exceedingly quick of movement and very tenacious of life. Specimens placed in a pail of formalin 

 escaped when the lid was raised. 



Life colors of one from a mud puddle at Apia, mottled gray; speckles on head pure white, others 

 dull whitish; silvery cross-streaks on side, some light and a few dark streaks on body; dorsal with 

 spots of pure bluish white below, then black, then edged with dull white; second dorsal reddish 

 brown above, then a white band, then a black one, then dull olive reticulations around pale spots; 

 caudal lislit and dark olive; anal pale grayish; ventral gray, with dusky center; upper surface black, 

 [ii\\v edgc'.l; under side of head livid gray, with pale or white spots; pectoral dotted much like caudal. 



A specimen taken in coral sand in the sea at Pago Pago was olive, bai'k with nine dark cross-bands, 

 unequal, some of them oblique; head and sides with gray dots and marblings; a dark bar from front 

 of eye down and forward; one down and back from posterior part of eye; first donsal very small, vii, 

 with a dark bar at base; second with oblique black cross-streaks; caudal with four or five dark cross- 

 streaks; pectoral with a black dot at base above and faint cross-streaks; ventral and pectoral pale; 

 ventral separate. In spite of the small number of dorsal rays, this specimen is probably identical with 

 the others of this variable species. 



PEKIOPHTHALMODON Gill. 



This genus is close to Feriophthalmus, differing in the shorter spinous dorsal, the ventrals mostly 

 united in the adult.

CHLAMYDES Jenkins. 

 Chlamydes Jenkins, Bull. U. S. Fish Comm., xxii, 1902 (1903), 50.3 {lalicepn). 

 This genus has the general character of Gohius, including the silk-like fring'e to the pectorals, but 

 the cheeks and opercles are covered with scales.

GNATHOLEFIS Sleeker. 



Gnatholepis Bleeker, Arch. Neerl. 1875, 318 (mjereiisis). 



Hamis Jordan & Snyder, Proc. U. S. Nat. Mus., xxiv, 1902 (1901), 51 {otakii). 

 This genus has the character of Rhinogobius, except that the cheeks and opercles are covered 

 with large scales. The species are small, pale in color, and live about the coral reefs. Gnatholepis 

 thumpnorii is found in the West Indies, Gnatholepis otak-li in Japan. The tongue is notched in 

 Gnrdholepis (lelloides, thompsoni, knighti, and otakri. Gnatholepis anjerensis we have not seen, but the 

 scanty description approaches G. delloides. 



1437. Gnatholepis deltoides (Seale). Guam; Samoa.

ftxnalhulepu anjerensis Bleeker, Arch. Neerl., ix, 318, 1875. "Caput superne lateribusque squamatum." 

 This species apparently differs from Gnatholepis anjerensis (Bleeker), the type of the genus Gnath- 

 olepis, in the smaller scales and more elongate body. The scanty description of the latter, with no 

 reference to the color, renders it diflScult to make a positive identification. The longer caudal, 4J 

 instead of 5 in total length, also may be diatmctive. 



Gnajhdepis knighti from Hawaii is very close to the present species, but has smaller scales, 32-9. 

 The coloration is very smiilar to that of our specimens called Gnatholepis samoensis.
