The first rays of the first Dorsal are longest; the 
seventh, eighth and ninth rays are next in length : 
in other words, this fin at first sight appears as if 
divided, or as two fins. Delicate tentaculæ are sus- 
pended from the extremities of the rays of this fin. 
Just back of the first Dorsal arises the second, 
appearing as if connected, and hence described by 
Mitchell as one fin ; height of this fin to its length 
as one to three. 
The Pectorals are very large, when expanded re- 
sembling a wing; the rays are uncommonly dis- 
tinct. These fins arise from the entire lower edge 
of the branchial aperture: height to length as four 
to two and a half. 
The Ventrals arise just back of the first rays of 
the pectorals ; they are composed of three rays—the 
first ray shorter than the segond, and exceedingly 
stout. 
The Anus is situated sai distant from the ven- 
tral and anal fins. - 
The Anal fin commences and terminates on the 
same plane with the second dorsal : the rays of this 
fin are deeply divided at their extremities: length of 
fin to its height as three and a half to one and a 
half. 
Length of Caudal fin to its height as two. to 
three :—the color of rays similar to that of the body. 
The fin rays are as follows: D. 16, 13; P. 18; 
V. 3; A. 15; C. 19.
