SHORE FISHES OF GALAPAGOS ISLANDS 353 



Range. Cosmopolitan. 



This widely distributed species was taken by the Albatross (1887- 

 *SS) at Chatham and Hood islands, Galapagos Archipelago. 



30. MUGIL THOBURNI Jordan & Starks. 



Mugil thoburni JORDAN & STARKS in Jordan & Evermann, Fishes North and 

 Mid. Amer., I, 812, 1896, Galapagos Islands. 



Range. Pacific coast of tropical America ; Galapagos Islands. 



Specimens taken in Tagus Cove and Elizabeth Bay, Albemarle ; and 

 in shallow lagoons of the mangrove swamps on the east coast of 

 Narboro. 



We have numerous young individuals taken in a seine from the surf 

 on a beach north of Tagus Cove, Albemarle. These are certainly 

 the young of Mugil thoburni; they have the same number of fin rays, 

 and the black base of the pectoral, characteristic of the adult, is con- 

 spicuously present in all. The head, however, is very strikingly dif- 

 ferent in shape from that of the adult, being compressed and deep 

 rather than wide and depressed ; but the specimens present a perfect 

 gradation in this respect from the smallest to the largest. In a speci- 

 men 27 mm. long, the interorbital space is .22 of the length of the 

 head; in a specimen 38 mm. long .25 ; in one 62 mm. long .31 ; and 

 in an adult 159 mm. long .38. The ridges on the rows of scales are 

 present on specimens 40 mm. long, but on specimens smaller than this 

 they are not yet developed. The adipose eye-lids are slightly de- 

 veloped in specimens 65 mm. long; the smaller ones have the eye- 

 lids simple.
