348 COTTID^. 



Aspidophorus of Lacepede and Cuvier. Another Greenland 

 species (Coitus porosus) is added in the 'Histoire des Poissons' 

 (t. viii.) ; and Professor Reinhardt, of Copenhagen, notices two 

 others, Cottus uncinatus and Triglops Pingelii. Kroyer (Nat. 

 Tidskr. N. Rakk.) subdivided the northern Cotti, making the 

 Cottus tricuspis of Reinhardt, identified with C. gobio of Fabri- 

 cius, the type of his genus Phobetor, which wants vomerine 

 teeth, while his genus Icelus has palatine teeth, in addition to 

 the dentition of the vomer and jaws. To it belong Cottus 

 uncinatus and C. bicornis of Reinhardt, and a Spitzbergen 

 species, Icelus hamatus (Kroyer). Mr. Girard, in a Mono- 

 graph published in the ' Smithsonian Contributions to Know- 

 ledge, December, 1850,' has carried the dismemberment of 

 Artedi's genus Cottus still further. To the marine species he 

 has given the name of Acanthocottus, reserving the original 

 generic appellation to the Cottus gobio and its numerous allies, 

 inhabitants of fresh waters. The American species of Cottus, as 

 restricted by Mr. Girard, are, 1 . C. cognatus (Richardson) , an 

 inhabitant of Great Bear Lake, under the Arctic circle ; 2. C. 

 Richardsonii (Agassiz), taken on the northern coasts of Lake 

 Superior; 3. C. Franklinii (Agassiz), frequenting the southern 

 shores of the same great lake ; 4. C. Alvordii (Girard) , Fort 

 Gratiot, Lake Huron ; 5. C. formosus (Girard), Lake Ontario ; 

 6. C. gracilis (Heckel, or Uranidea quiescens of Dekay), New 

 England and New York; 7. C. gobioides (Girard), Lake Cham- 

 plain; 8. C. boleoides (Girard), Vermont; 9. C. Bairdii (Gi- 

 rard), Mahoning River, Ohio ; 10. C. Wilsoni (Girard) , eastern 

 tributaries of the Ohio ; 11. C. viscosus (Haldeman), Eastern 

 Pennsylvania and Maryland; 12. C. meridionalis (Girard), 

 James River, Virginia. 



I avail myself of this opportunity to remove a nominal spe- 

 cies from the list of American fish. The Cottus hexacornis 

 (Richardson) was found at the mouth of the Coppermine River 

 in June, 1821, on Sir John Franklin's First Expedition; and 

 a description of the recent fish was entered in my note-book 

 at the time, but the specimens were lost during the calamitous
