 logue Fish. North America, 106, 1885. 



Habitat. — Grulf of Mexico. 



This strongly marked species has no near relative among our Gobies. 

 The many specimens before us are all from Pensacola, where it is a com- 

 mon inhabitant of the grassy bays. 



42. Microgobius thalassinus.

 (Charleston Harbor) ; Jordan, Catalogue Fish. North America, 106, 1885 

 (name only). 



Habitat. — South Atlantic Coast of United States ; Charleston. 

 This species is known, as yet, only from the original types taken by 

 Professor Gilbert in Charleston Harbor. 



43. Microgobius signatus.

 (Cuba) Jordan, Proc. U. S. Nat. Mus., 1886, 49 (Havana, Cuba). 



Habitat. — West Indian fauna ; Cuba. 



The numerous specimens of this species examined by us were ob- 

 tained by Dr. Jordan in the Havana market. The sexual differences

 the species shows.
