SQUALID/E. 



Pise. III. p. 13, tab. II. figs. 3, 4. This species has only 

 as yet been met with on the coast of Brazil. 



No. 3. Zygoena Blocln'i, Cuv. Regne An. t. ii. Bloch, 

 pi. 117. The locality from which this species was obtained 

 is unknown, but specimens are still preserved. 



No. 4. Zygoena laticeps, Cantor. This is a new species 

 lately described and figured by Dr. Theodore Cantor, who 

 obtained it in the Bay of Bengal, and in which the head is 

 still wider than in either of the other known species ; a 

 straight line drawn from the one eye to the other is equal to 

 about one half of the total length of the fish. 



In shape the fins are like those of the four species already 

 known ; the only difference I have observed, says Dr. Cantor, 

 is the situation of the anal fin, which in the present species is 

 somewhat anterior to the second dorsal, while these fins in the 

 others are opposite.
