FISHES OF THE GULF OF MAINE 



377 



off Gloucester, 68 and in Ipswich Bay, 69 and that 1 1 

 specimens, about 6 to 8 inches long, were taken 

 in a fish trap at Barnstable on the shore of Cape 

 Cod Bay on September 6, 1950, shows that it is 

 more likely to round Cape Cod than is the crevalle. 

 It is also reported from outer Nova Scotia. 70 

 Young fish are not rare about Woods Hole and 

 thence westward from July to November. 



Saurel Trachurus trachurus (Linnaeus) 1758 



ROUGH SCAD 



Jordan and Evermann, 1899-1900, p. 910." 



Description. — The saurel is distinguishable from 

 all allied species yet known from New England 

 waters by having about 75 bony plates along its 

 lateral lines, as contrasted with about 30 or fewer 

 in other Gulf of Maine carangids. It is a some- 

 what deeper fish than the mackerel scad but more 

 slender than the hardtail or the crevalle, its body 

 (to the base of tail) being about 3% times as long 

 as it is deep. Its first dorsal fin, of 8 spines, is 

 closely followed by the long second dorsal of 25 

 to 30 soft rays. Its soft anal, opposite the second 

 dorsal, has 24 to 26 rays, and is preceded by two 

 small detached spines. The tail is deeply forked

M Specimen now in the collection of the Boston Society of Natural History. 



70 A 5-inch specimen is reported from Port Mouton by Leim (Proc. Nova 

 Scotian Inst. Sci., vol. 17, 1930, No. 4, p. xlvi), and small ones from Pubnico, 

 and near Halifax, by Vladykov (Proc. Nova Scotian Inst. Sci., vol. 19, 1935, 

 p. 4). 



"Nichols (Bull. Amer. Mus. Nat. Hist., vol. 42, 1920, p. 479) considers 

 tbe western Atlantic saurel distinct from the eastern Atlantic saurel and 

 has proposed tbe name lalhumi for it. But this separation has not been 

 adopted generally. 



Color. — Described as bluish green above, silvery 

 below, with a black spot on the edge of the gill 

 cover above its rear angle. 



Size. — LeDgth about one foot. 



General range. — Known from nearly all warm 

 and temperate seas, sometimes common off the 

 Florida Keys. A few have been recorded from 

 the vicinity of New York, one from Newport, 

 R. I., and three from the Gulf of Maine. 



Occurrence in the Gulf of Maine. — One specimen 

 of this rare fish was taken in Casco Bay on August 

 12, a second at Castine, Maine, on October 15, 

 1930, 72 and a third at Sandwich, Mass., on Cape 

 Cod Bay in the summer of 1950. 73 



Goggle-eyed scad Trachurops crumenophthalmus 

 (Bloch) 1793 



Goggler; Goggle eye jack 



Jordan and Evermann, 1896-1900, p. 911. 



Description. — This scad resembles the mackerel 

 scad (p. 374) in general appearance, but it has 

 larger eyes aDd lacks the detached finlets behind 

 the dorsal and anal fins. Its high first dorsal fin 

 separates it readily from the pilotfish (p. 372), 

 while the fact that the forward half of its lateral 

 line is only slightly arched instead of strongly so 

 obviates any danger of confusing it with the 

 crevalle (p. 375), the hardtail (p. 376), or the saurel 

 (p. 377). Its first dorsal fin has 8 spines, its second 

 dorsal is of 1 spine followed by 23 to 26 soft rays;

 in the Museum of Comparative Zoology.
