Mahitat. — West Indian fauna 5 Nortb to South Carolina and Texas. 



This species is generally common in the West Indies. The specimens 

 before us are all from Havana, except one, a large example from St. Jo- 

 seph's Bay, Florida. 



This species differs considerably from the typical species of Gobius, 

 but a series of intermediate forms renders it impossible to detine it as 

 a distinct genus, or even subgenus. Different specimens show consid- 

 erable variations in the size of the scales, but there is not much doubt 

 that all the names included in the foregoing synonymy belong to one 

 species, for which the earliest name is that of Pallas. 



34. Gobius paradoxus. 



Gobius jiaradoxus Giinther, Proc. Zool. Soc, London, 1861, 3 (west coast Cen- 

 tral America); Giinther, Cat. Fish. Brit. Mus., iii, 549, 1861 (west coast 

 Central America); Jordan &, Gilbert, Bull. U. S. Fish Com., 1882, iii 

 (Panama); Jordan & Gilbert, Proc. U. S. Nat. Mus., 1882, 626 (Panama). 



Habitat. — Pacific coast of Tropical America; Panama. 



This species is not rare at Panama where specimens were obtained 

 by Professor Gilbert. As these are not now at hand, we are compelled 

 to fall back on Dr. Giinther's description. This species is a very pecu- 

 liar one in regard to its squamation and the development of its spines, 

 and it may be perhaps properly the type of a distinct genus. 



35. Gobius seminudus. 



Gobius seminudus Giinther, Proc. Zool. Soc, London, 1861, 3 (west coast Cen- 

 tral America); Giiuther, Cat. Fish. Brit. Mns., iii, 554, 1861 (west coast 

 Central America); Jordan & Gilbert, Bull. U. S. Fish Com., 1882, iii 

 (Panama); Jordan, Proc. U. S. Nat. Mus., 1885 (Panama). 



Habitat. — Pacific coast of Central America. 



This species was obtained by Professor Gilbert at Panama. As his 

 specimens have been unfortunately destroyed, we here use the descrip- 

 tion of Dr. Giinther. 



It is remarkable that in the Panama fauna are four gobies, not espe- 

 cially related to each other, each of which has the anterior half of the 

 body naked, this region in all our other gobies being scaled. These are 

 Gymneleotris seminuda, Gobius paradoxtts, Gobius seminudus, and Micro- 

 gobius emblematicus. Can there be any physical cause for this?
