as is also the bonito, 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. HE. Palmer. 
Hulamia Milberti Gill. Blue Shark. 
A large specimen caught at Wood’s Holl, in August, contained a 
quantity of small bivalve shells, Yoldia sidpotisias 
The common food of this species was the squeteague (C; ynoscion re- 
galis), and the bonito (Sarda pelamys). One individual contained a five- 
pound mackerel; another had a large codfish hook and piece of line. 
Seup, 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. 
Galeocerdo tigrinus Mill. & 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. EH. Palmer. 
Mustelus canis De Kay. Dogfish. 
Several specimens caught at Wood’s Holl, in August, contained lob- 
sters, Homarus americanus ; spider-crabs, Libinia canaliculata ; rock- 
crabs, Cancer irroratus ; Tautog (Tautoga onitis); and butterfish (Poro- 
notus triacanthus). Wood’s Holl, i871. EH. Palmer. 
Eugomphodus littoralis 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. IE. 
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 coastof Maine. It has not been well described but it is appa- 
rently the Holothuria chrysacanthophora of Couthouy and the Lehiurus 
chrysacanthophorus of Pourtales. It has been generally considered a 
rare species, and specimens of itare 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.
