No. II, confined to dark brown ckromatophores on the tip of tke 
tail. The pectoral tins still have embryonic fin rays, which is also 
the case in the vertical fins, but distinet interspinal elements are 
now developed to the number of about 112 in the anal fin and 
about 140 in the dorsal fin; (damage of the fins caused some 
difficulty in the exact counting of the interspinalia). 
Fig. 9 represents the head, which is not so distinctly marked 
from the body and has a more depressed form than in the above 
mentioned specimen. In the upper jaw there are 4 smaller and 8 
larger teeth on each side, but the foremost tooth, which has a 
slight curvature at the base and is fastened outermost at the upper 
side of the upper jaw, was broken and is not figured. The lower 
jaw has 3 smaller and 8 larger teeth on each side. For the rest 
the teeth are exaetly as those mentioned above. 
The number of segments is about 91 præanal and 67 post¬ 
anal, or about 158 in all.

In „Leptocephalids in the University zoological museum of 
Upsala“ by Dr. Pehr Stromman, a species is described under the 
name Leptocephalus lanceolatus, which agrees in several regards with 
my specimens Nos. II and III; unfortunately the number of segments 
is not indicated. Meantime Dr. Joh s. Schmidt in his recently 
published „Contributions to the biology of some North Atlantic 
species of Eels u (Yidensk. Medd. Naturh. Forening København, Vol. 64. 
1912), after having examined the type specimens of this species, 
gives the number of myomeres as ca. 160, of which about 88 pre- 
anal. After this it can scarcely be doubted that my specimens 
| Nr. II and III are really this species.
