Sub-class Teleostei. Scombroids. 



We have one very rare species of tins genus, occasionally found 

 on our coast, viz : 



Gybium maculatum, Slorer. 

 Spanish Mackerel. 

 This is characterized as large, — numerous greyish brown spots 

 distributed along the sides. Length one to two feet. 



This species has been placed by Prof Gill into the Orcyninse 

 sub-family and into the genus Apodoniis of Bennet. Its specific 

 name under this arrangement is Apodontis maculakis, Gill, and is 

 synonymous with the Scomber colias, (Storer) and la maquereau 

 colias of Cuvier and Valenciennes. 



Genus Vomer, Guv. 



Gen. Char. Body compressed. No filaments or prolongations of the fins 

 Profile nearly vertical. 



Sub-family Caeangin^. Vomer setipinnis, Ayres. 

 Blunt-nosed Shiner. 

 This species is inserted here on the authority of another. I 

 have never met with it in our waters and have considei-ed, on the 

 statement of DeKay, that New York, or the southern coast of 

 Massachusetts was its northern limit. It has been described as 

 the body of a lustrous silvery tint, passing into a leaden tint on 

 the back. Iris yellow ; membrane of the second dorsal minutely 

 dotted with black, tinged at its base with light yellow. Pectorals 

 olive green, verging to dusky. 



First dorsal composed of short isolated rays deeply hidden in 

 a groove. 



Ray formula — 



D. 7, 1, 22; P. 1, 18; V. 1, 3, A. 1, 18. 

 air bladder very large with two horns behind. 



This has very recently been placed into the sub-family Garangince 

 (Bona.) Its synonymes are 



Vomer Brownii. Cuv. 

 Zeus setapinnis. Mitch. 



Sub-family Seriolin^. Genus Temnodon, Guv. 



Gen. Char. The tail unarmed, the little fins or detached spines are before the 

 anal as in Seriola. The first dorsal, fragile and long, the second and the anal cov-
