head to caudal, two dark streaks from eye to mouth ; fius 

 variegated with brown, as in Gohhts banana ; a brown mark 

 on ujiper ])art of base of pectoral. 



One specimen in the British-Museum collection, from 

 Surinam, 3 inches long. 



Euctenogobius Jahis, sp. n. 

 D.6i. A.l. L.lat.60. 



The depth of the body is contained eight times and a half 

 in the total length, being less than half the lengtli of the 

 head, which is very large and broad, its length one fourth 

 of the total, its breadth more than half its length and much 

 greater than its depth. Muzzle prolonged, broad and flattened 

 above, nearly half the length of the head ; upper jaw over- 

 lapping the lower. Teeth rather stout, in one series only in 

 the upper jaw. Eyes small, on the upper surface of the head ; 

 their diameter equal to the interorbital space, and one third of 

 the length of the snout. Head naked. Scales small in front 

 of dorsal, large on the body ; thirteen series between dorsal 

 and anal. Ventral not reaching to vent ; pectoral longer ; first 

 dorsal rather higher than the body and than tlic second dorsal ; 

 caudal rounded, rather more than one sixth of the total length. 

 Reddish or yellowish brown, with dark bro^^^l si)ots and varie- 

 gations on the sides ; fins ban'cd and spotted with dark brown ; 

 the second dorsal with regular variegations between the rays ; 

 anal grey. 



This species presents a considerable resemblance to Gohius 

 banana and G. transandeanus • but the teeth are distinctly 

 those o£ Euctenogobius. We are not told Avhether Gobius 

 doh'chocep/ialus, Cope, Trans. Amer. Phil. Soc. xiii. p. 403, 

 has the teeth in one or more series in the upper jaw ; but 

 a comparison with the descriptions of that species and of 

 Euctenogobius badius, Gill, Ann. Lye. N. H. New York, vii. 

 p. 45, shows that the present species differs considerably from 

 both of them. 



One specimen in the collection of the British Museum was 

 collected by Dr. Wucherer at Bahia. Length 6^ inches.
