THE FISHES OF SAMOA. 



403 



Those found in lava are largely black. The young have black cross-bands which vanish with 

 age. Those from Panama and Clarion islands show a little spotting of white and a trace of a black 

 lengthwise band. 



We have thus far failed to separate the Pacific species called Gobius albopuncHUus from the widely 

 diffused and very common Gobius i ,r Mapo soporator of the American coasts.

Head 3 in length; depth 4.75; eye 4.5 in head; dorsal vr, 10; anal 9; scales 32 counting from 

 posterior margin of opercle; interorbital very narrow, scarcely wider than profile of eye; snout 3.75 in 

 head; tongue emarginate. 



Body elongate, compressed, largest at head, the cheeks being extremely gibbous, the head being 

 as wide as long, and much wider than deep; cheeks and interorbital region, naked; mouth rather 

 large, with several rows of small sharp-pointed teeth; angle of jaws not reaching to below middle of 

 eye; jaws equal in length; opercle and preopercle entire; about 12 fine silky rays on upper base 

 of pectoral; depth of caudal peduncle 2.95; origin of spinous dorsal posterior to a line with axil of 



'/zin. 



Fig. 92. — Mapo crassiceps Jordan & Seale, new species. Type. 



ventrals; base of spinous dorsal 2 in length; base of soft dorsal 1.75 in head, its longest ray 2.5 in head; 

 base of anal 2. IS in head, longest ray about 2 in head, origin of anal midway between base of caudal 

 and posterior margin of preopercle; pectorals 1.1 in head, the tips on a line with origin of soft dorsal: 

 ventral disk 2 in head, the anterior membrane of the fin with 3 points; caudal rounded, 1.25 in head. 



Color in spirits, whitish with slight dusky wash, a small black dot just back of eye; opercle and 

 base of pectorals usually darker; posterior part of spinous dorsal with a black blotch; soft dorsal dusky, 

 darker in middle;, caudal dusky; anal dusky, lighter on base, pectoral and ventral dusky. 



Life colors of a specimen from Apia, yellowish-olive, mottled all over with blackish and grayish; 

 grayish spots on cheeks; fins all dusky, more or less barred; axil dusky. 



The species is very close to Mnpr, fiiscus, differing in the tumid cheeks and plain coloration. 



Nine specimens from Apia taken in the mouth of the river Vaisigano and one from the Bay of 

 Apia. The type is no. 51777, CJ. S. National Museum, from Apia, length 2.1 inches. 



GLOSSOGOBITJS Gill. 

 1463. Glossog-obius vaisiganis Jordan & Seale, new species. Samoa. 



Head, to tip of lower jaw, 3 in length; depth 5.5; eye. 6 in head; dorsal vi, 10; anal 10; scales 29; 

 snout 3.6 in head; interorbital very narrow, scarcely greater than pupil; eyes on dorsal profile. 



Body elongate, compressed, largest at j^ectoral girdle; head pointed, the lower jaw the longer, 

 about one-half the width of eye, longer than upper jaw; mouth large, the angle below the posterior 

 margin of eye; several rows of fine sharp-pointed teeth in the jaws and on vomer; tongue deeply 

 forked; caudal peduncle 3.25 in head; anal papilla distinct; origin of spinous dorsal slightly posterior 

 to line with axil of ventral, its base 3 in head; base of soft dorsal 1.5 in head, its longest ray 2 in head; 

 anal fin similar to soft dorsal, its size slightly smaller and its origin a little posterior to line with origin 

 of soft dorsal, its origin nearer to base of caudal than to eye; pectoral extending to a line with origin 

 of soft dorsal; origin of ventrals directly below base of pectoral, their tip extending to anal papilla: 

 ventral fins united and with a shallow membranous cup; caudal rounded, 1.5 in head.
