FISHES OF THE GULF OF MAINE 335 



Hook-eared sculpin, Artediellus uncinatus (Reinhardt) l0 



This sculpin is now known to be generally distributed in the Gidf of Maine in 

 depths greater than 20 to 30 fathoms. Thus, in addition to the Massachusetts Bay 

 records of many years ago, we have recently taken it repeatedly near Mount Desert, 

 off Cape Elizabeth, near Jeffrey's Ledge, around Cashes Ledge, along the northern 

 slopes of Georges Bank, in the southeastern part of the basin of the gulf, and at the 

 entrance to the deep gully between Georges and Browns Banks, in depths ranging 

 from 20 to 150 fathoms. Individual hauls have yielded up to six or eight specimens, 

 both on hard and on soft bottom. 



After examining specimens from New England waters and comparing published 

 drawings of European fish, we can find no major differences between the hook-eared 

 sculpins of the eastern and western Atlantic. 11 



Mailed sculpin, Triglops ommatistius Gilbert 



This sculpin is not as rare in the Gulf of Maine as was formerly supposed, for 

 during the past few years we have trawled specimens near Mount Desert, in Mas- 

 sachusetts Bay, off Cape Ann, off Cape Cod, and around the northern slope of Georges 

 Bank, in depths of 20 to 140 fathoms, in various months from spring to autumn. 

 The most southerly locality was about 10 miles east of Chatham. 



Longhorn sculpin, Myoxocephalus octodecimspinosus (Mitchill) 



Numerous young specimens 1% to 2 inches long taken in September, and 3 to 3% 

 inches in February, suggest that the longhorn sculpin is about 2 to 3 inches long at 1 

 year of age, spawning as it does in late fall. 



Deep-sea sculpin, Cottunculus microps Collett 



A specimen, about 2 inches long, trawled by the Albatross II on the northern 

 slope of Georges Bank, in a depth of 120 fathoms, on July 24, 1931, is the third 

 record for the Gulf of Maine proper. 



Sea raven, Hemitripterus americanus (Gmelin) 



The fact that fish of both sexes with gonads only partially developed have recently 

 been found on Nantucket Shoals late in June, added to previous captures of ripe 

 females off southern New England in November and December shows this to be a 

 late fall and early winter spawner. The sea raven is a prolific fish, for a female 20 

 inches long that we caught off Boothbay Harbor, Maine, in April 1925, contained 

 about 10,000 eggs. The fact that these were definitely of two sizes, the smaller 

 averaging 1 .5 mm in diameter, the larger about 3 mm, raises the interesting question 

 whether individual sea ravens may spawn more than once during the year. 



The sizes of the few young sea ravens that have been taken in the Gulf of Maine 

 suggest that they reach a length of 2 to 4 inches by the middle of the first summer, 

 when 6 to 8 months old; and about 6 inches by the following April, at an age of 1% 

 years. 



10 Given as Artediellus atlanlkus Jordan and Evermann by Bigelow and Welsh (1925, p. 314). 



" Jordan, Evermann, and Clark (193d, p. 377) in the Check List of Fishes placed Artediellus attavticus Jordan and Evermann 

 in the synonymy of A. uncinatux Reinhard*t
