as is also the bouito, as many as three of the latter being sometimes 

 found in the stomach of a single individual. Other animals that serve 

 as food are the herring, horse-mackerel, skate's eggs, crabs, and lob- 

 sters. Wood's Holl, Mass., 1871. E. Palmer. 

 Eulamia Milberti Gill. Blue Shark. 



A large specimen caught at Wood's Holl, in August, contained a 

 quantity of small bivalve shells, Yoldia sapotilla. 



The common food of this species was the squeteague (Cynoscion re- 

 galis), and the bonito (Sarda pelamys). One individual contained a five- 

 pound mackerel ; another had a large codfish hook and piece of line. 

 Scup, the common skate, sea bass, and a small shell (Yoldia sapotilla), 

 also served as food. Three bonitos were often found in a single speci- 

 men. Wood's Holl, 1871. E. Palmer. 

 Caleocerdo tigrlnus Mull. & Henle. Tiger Shark. 



Specimens caught at Wood's Holl, in August, contained large uni- 

 valve shells, Buccinum undatum and Lunatia heros. 



One contained a quantity of pork in large pieces, while others had 

 fed upon sea turtle, the common ray, sting-ray, bluefish, dogfish ; quan- 

 tities of feathers and eel-grass were also found in the stomachs of this 

 species. Wood's Holl, 1871. E. Palmer. 

 Mustelus canis De Kay. Dogfish. 



Several specimens caught at Wood's Holl, in August, contained lob- 

 sters, Homarus americanus ; spider-crabs, Libinia, canal iculata ; rock- 

 crabs, Cancer irroratus; Tautog (Tautoga onitis) ; and butterftsh (Poro- 

 notus triacanthus). Wood's Holl, 1871. E. Palmer. 

 Eugomplwdus Uttoralis Gill. Sand Shark. 



Many specimens taken at Wood's Holl, in July and August, contained 

 lobsters, Homarus americanus, in abundance; Cancer irroratus; and 

 squids, Loligo Pealii. » 



Also menhaden, Brevoortia tyrannus; eels; and common flounder. E. 

 Palmer, 1871. 

 Squalus americanus. 



Specimens taken in the rivers near Eastport, Me., in 1871, associated 

 with herring, were full of the latter fish. A. E. Verrill, 1871. 



A Gephyrean worm is often used for bait by the fishermen on some 

 parts of the coast of Maine. It has not been well described but it is appa- 

 rently the Holothuria clirysacantliophora of Couthouy and the Echiurus 

 chrysacanthophorus of Pourtales. It has been generally considered a 

 rare species, and specimens of it are uncommon in museums. At Harps- 

 well the fishermen sometimes dig it in immense quantities. It lives in 

 the mud, just above the low-water mark, and is'as readily obtained as 

 clams. It is used in catching several species of fishes, but is specially 

 desirable for hake. Its irregularity of occurrence seems to be the only 

 reason why it should not be more extensively employed.
