very rare and its habits little known. "We dug two specimens 

 out of the sand near low-water mark, where they burrowed to the 

 depth of a foot or more. When placed upon moist sand they 

 burrowed into it, tail foremost, with surprising rapidity, disap- 

 pearing in an instant. 



At Fire Island on the southern side of Long Island, Mr. S. I. 

 Smith observed last August a species of worm (^Heterwiereis) of 

 a reddish colour and two or three inches Ions:, swimmins: in lar2;e 

 numbers at and near the surface. These were at that time the 

 favourite food of the Blue-fish (Temnodon saltator). 



AtEastport in Maine, and at Grand Menan, during several years 

 past, I have made many observations on this subject, but mostly 

 relating to fishes of which the habits are better known, like the 

 cod, hake, haddock, etc. 



The Wolf-fish (^Anarrhicas vomerinus) is not at all particular 

 as to its food. At Eastport I took from the stomach of a large 

 one at least four quarts of the common round sea-urchin {Eury- 

 ecJiinus Drohachiensis,) , most of them with the spines on, and 

 many of them quite entire. From another I took an equal quan- 

 tity of a mixture of the same sea-urchin and the large whelk 

 (^Buccinum unclulatuiii). Many of the latter were entire or but 

 slightly cracked. 



The Sculpins not unfrequently swallow entire, large specimens 

 of several crabs (^Cancer irroratus, Hijas coarctatus, etc.) 



The Haddock is addicted to the same habit, but is a general 

 feeder, swallowing all sorts of mollusca, worms, fishes, etc. 



The Herring (^Cliipea elongata) in the Bay of Fundy feeds 

 very extensively, at least during all the months when I have ob- 

 served them (June to November), upon several species of My sis 

 and of ThysanojJoda^ called 'shrimp 'by the fishermen, which 

 swim free, at and near the surfiice, in extensive ' schools,' and are 

 persistently pursued by the herring. The commonest species, 

 apparently a Thysanopoda, is about an inch and a half long, of 

 a pale reddish colour. The species of Mysis are smaller and 

 paler ; the two genera often occur together. Young Pollock or 

 Coal-fish, four to ten inches long, pursue the same species in 

 large schools, often coming around the wharves of Eastport in 

 great numbers in eager pursuit of their prey, and by leaping out 

 after them, produce a great commotion in the water. When 

 thus pursued the Thysanopoda will leap out of the water to the 

 height of a foot or more. The common Sebastes, or Red Perch,
