504 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 



List of species inhabiting sandy and gravelly bottoms. 



In the following list I have included nearly all the species that 

 ordinarily occurred on those bottoms in which sand predominated, even 

 though some of them are more strictly muddy-bottom species. Others 

 belong more properly on rocky, stony, or shelly bottoms, but are intro- 

 duced here because they occur attached to the scattered shells and stones 

 that are always liable to be met with on sandy bottoms. 



In order to designate those species that are more strictly character- 

 istic of the clear sandy bottoms, I have prefixed to them a dagger, 

 (thus : t.) To show the character of the fauna on the bottoms Of mixed 

 or intermediate character, I have selected a single locality, 86, b, south" 

 west of Cuttyhunk Island and opposite the mouth of Buzzard's Bay, 

 where the depth was twenty-five fathoms, and the bottom consisted of 

 fine sand mixed with some mud and gravel, with a few small scattered 

 stones, and have prefixed an asterisk (thus : *) to such species as occurred 

 at that particular locality, though most of them occurred also at other 

 localities.
