Leptocephalus Hjorti n. sp. 
Fig. 1 is a pliotograph in 5 Is times enlargement. Fig. 2, 
wtiich represents the same specimen, drawn with piism, shows 
the extension of the pigment. 
This consists of apparently black, 
but in reality brown, mostly 
branched chromatophores, which 
chiefiy follow the chorda and the 
upper margin of the alimentary 
canal, as shown in the figure. 
On two places only, at a distance of respectively 6 and 11 mm 
from the point of the snout, there are great, branched chromato¬ 
phores on the under side of the alimentary canal. At the tip of 
Fig. 2. ca. 5:1. 
the tail the chromatophores form a continuous row above and below 
along the base of the tail fin. For the rest the form of the body is 
— as in other Leptocephalids — very strongly compressed. The 
vertical fins are little developed; in the extreme part of the tail 
fin only embryonic fin rays are 
to be seen. Interspinal elements 
are still wanting. The pectoral 
fins are nearly rudimentary. 
Fig. 3 shows the head; the lower 
jaw is more projecting than the 
upper, which has 6 forward point- 
ing teeth on each side; the hind¬ 
most tooth is verv small (not shown in the figure). In the lower 
jaw only 5 projecting teeth are seen on each side. All the teeth 
are long, straight and pointed, except the 2 foremost in the uppei 
and lower jaw; these have namelv a slight curvature at the 
Fig. 3. 17 :1.
