18. Bollmannia Jordan gen. nov. 



Diagnosis. — This new genus differs from Lepidogobius by having no 

 fleshy processes on inner edge of shoulder girdle, the iuterorbital area 

 narrower and without trace of median keel, and by the very large etenoid 

 scales. From Gobius proper it is distinguished by the presence of 7 

 dorsal spines and by the presence of large scales on the cheeks. 



I have named this genus in honor of my late colleague, Mr. Charles 

 Harvey Bollmau, whose untimely death while engaged in the explora- 

 tion of the rivers of Georgia, took place while this paper was passing 

 through the press. — D. S. J.
