382 THE PEOCEEDINGS OF THE LTNNEAN SOCIETY 



General color, of a dark brownish grey, the lower parts of a 

 dirty white, a badly defined white stripe ou each side of the 

 body. 



I believe this fish to be very scarce at Sydney, as it was 

 unknown to the fishmongers. 



The length of the above described specimen is two feet ten 

 inches ; it was caught on the 20th February, 1878. 



By the form of its caudal it seems to differ from the Indian 

 species, but this may be owing to its old age. 



ECHENEIS NADCRATES. 



EcJieneis naucrates, Linn. Syst. Nat., Vol.1, p. 441. 



This curious fish is found in nearly all the warm seas of the 

 world ; I saw it at Sydney in the month of April. 



The color is nearly black, tinged with slatey-grey, the lower 

 parts being of a dirty white. 



Auxis Ramsayi. 



Height of the body four and a half times in total length with- 

 out the caudal fin ; head, three and two-thirds in the same ; the 

 pectorals reach nearly to the end of the base of the dorsal, six 

 finlets behind the second dorsal, and the same number behind the 

 anal ; first dorsal with nine spines, second with the same number 

 of rays, anal with sixteen rays, the last elongated, and more than 

 half as long as the third, which is the longest. 



Scales, similar to those which form the corselet, but much 

 smaller, extend along the lateral line to the vertical from the 

 fifth dorsal finlet, forming a broad stripe ; lateral line undulated. 



The general colour is dark lead, the back is black with 

 numerous oblique bands of the same colour, extending to below the 

 lateral line as in Pelamys Sarda ; no trace of wavy black streaks; 

 the fins are whitish, with the anterior part of the first dorsal, and 

 the middle of the caudal obscure, the inner side of the pectorals 

 black. 



On the 6th April, 1878, numerous specimens of this species 

 appeared in the Sydney market, the fishmongers call them Jiorse 

 macherel; it is said to be a good fish for the table. I have dedi- 

 cated this species to the learned Curator of the Sydney Museum.
