posed of 96 to 102 long, flexible, simple rays, their tips apparently ex- 
tending far beyond the connecting membrane. The length of the longest 
rays (14) is double the least height of the body at the base of the tail 
(7). 
The anal fin originates at a distance (22) from the snout contained 
four times and one-half in the length of the body. It is composed of 
76 to 81 rays, the longest of which are as long as the head. 
The pectoral is inserted close to the gill-opening and far below the 
lateral line (midway from the black stripe upon the lateral line to the 
black stripe at the base of the interspinous processes of the anal fin). 
The pectoral upon the blind side is short, its length (2) equal to the 
diameter of the orbit, composed of about four or five rays; that upon 
- the colored side longer, its length (3) equal to that of the snout, and com- 
posed of about twelve rays. The ventrals are both crowded upon the 
ventral keel, their bases prolonged upon the keel, their tips embracing 
the origin of the anal. 
Radial formula: D. 96-102; A. 76-81; P. 12 left, 4-5 right. 
Color: In life colorless, translucent. In alcohol yellowish white. 
Three prominent blackish longitudinal stripes or lines upon the left side. 
The stripe running from the branchial cleft to the base of the tail is less 
prominent than the two at the bases of the interspinous processes. On 
the lateral line of the right side there is no stripe, though the two lateral 
stripes are aS prominent as upon the other side. Eyes black.
