AMERICAN GOBIID^ AND CALLIONYMID^. 53 



West Indian fauna from South Carolina to Para; Panama. 



The specimens in the Museum are from Charleston, S. C, Mobile 



Bay, Barbadoes, Sao Matheos, Cuba, Hayti," Porto Rico, St. 



Thomas, Martinique, Para, Gurupa and mouth of Rio Grande. 



Specimens 1^ inches long, collected by Mr. Samuel Gar- 

 man at Martinique, have interrupted cross bars of light and 

 dark. Numerous specimens of the same length from canals 

 in Para have similar, but fainter, markings; while many of 

 them have longitudinal lines formed by the occurrence of a 

 black spot on the centre of each scale. 



There seem to be two forms of the adult — one with the 

 profile gibbous, the dorsal outline forming a regular curve; 

 the other having the profile depressed over the eyes, the 

 anterior portion being sub-horizontal. The specimens from 

 Gurupa and the Rio Grande have the profile depressed; all 

 the other specimens have a gibbous profile. 



A comparison in detail of the two forms is appended. 

 Only extreme differences are given.
