specimens are taken by the cod and halibut schooners on George's 

 and other fishing banks at the depth of 80 to 400 fathoms. 



Family ALEPOCEPHALID^. 



135. Alepocephalus Bairdii Goode & Bean. Proc. U. S. National 

 Museum, ii, 1879. BAIRD'S ALEPOCEPHALUS. A single specimen about 

 two feet long was taken by one of the Gloucester fishing vessels on 

 the off-shore banks. Other genera of this family have recently been 

 described from the abyssal faunae of the mid-Atlantic and Pacific. 

 The genus Alepocephalus has heretofore been known only from the 

 Mediterranean. 



Family CLUPEID^E. 



136. Clupea harengus Linnaeus. HERRING. Clupea elongata 

 Storer, Hist. Fish. Mass., 1867, p. 152, pi. xxvi, fig. 1. The herring 

 schools make their appearance in October and November. They 

 spawn near the shores in November and December and on George's 

 banks later in the winter. 



137. Alosa sapidissima ( Wilson) Storer. SHAD. Alosa prces- 

 tabilis Storer, Hist. Fish. M'ass., 1867, p. 154, pi. xxvi, fig. 2. Shad 

 enter the rivers in May in large schools for the purpose of spawning. 

 They are often taken at sea in the fall. The Essex Institute has a 

 specimen from Salem harbor. 



138. Pomolobus vernalis (Mitch.} Goode & Bean. ALEWIFE. 

 Alosa tyrannus Storer, Hist. Fish. Mass., p. 156, pi. xxvi, fig. 3. Po- 

 molobus pseudoharengus Gill (in part). The alewives enter the rivers 

 with the shad in spring. They frequent the coasts in large schools in 

 summer, and some of them perhaps spawn at sea. 



139. Pomolobus sestivalis (Mitch.) Goode & Bean. BLUE BACK, 

 KYACK. Alosa cyanonoton Storer, Hist. Fish. Mass., p. 161, pi. xxvii, 

 fig. 1. Pomolobus pseudoharengus Gill (in part). This species, which 

 much resembles the preceding, from which it may be distinguished by 

 its smaller eyes, lower fins, and black lining of the abdominal cavity, 

 does not make its appearance until late spring and early summer. 



140. Pomolobus mediocris (Mitch.} Gill. HICKORY SHAD. 

 Alosa lineata Storer, Hist. Fish. Mass., 1867. p. 162, pi. xxvii, fig. 2. 

 Capt. Atwood and Dr. Storer speak of this fish as abundant at Prov- 

 incetown, and it doubtless occurs at the Essex County side of the bay. 

 It is easily distinguished from the common alewife by its projecting 

 under jaw. 



141. Brevoortia tyrannus (Latrobe) Goode. MENHADEN, POGY. 

 Alosa menhaden Storer, Hist. Fish. Mass., 1867, p. 158, pi. xxvi, fig. 4. 

 A common summer visitor, appearing in enormous schools in May and
