On the postlarval stages of the species of Paralepis 
Inhabiting the North Eastern part of the Atlantic 
incl. the Mediterranean. 
Preliminary note 
by 
Vilh. Ege, M. sc. 
(From the Danish Oceanographical Expeditions 1908—1910, 
Leader: Dr. Johs. Schmidt.) 
TVhe material upon which the present survey is based, comes 
mainly from the cruises of the Danish Research-Steamer "Thor" 
In the Mediterranean and in the Atlantic Ocean along the distance 
from Gibraltar to Iceland. Moreover supplementary material has 
been brought home by various other vessels fishing for the Danish 
Committee for the Study of the Sea. Through these supplementary 
Collections, mostly made in warmer parts of the Atlantic than those 
Visited by the ,Thor", the bulk of the material was considerably 
Increased and several new species were recorded. The study of 
this second part of the material at hand is, however, not so far | 
advanced that I have been able to include the new species in the 
Present survey. 
Key to the Mediterranean species. 
I. Pectorals prolonged (longer than head). 
Isolated large stellate chromatophores are present at base of 
Unpaired fins. Their position is as follows: 1) one at base of 
dorsal fin; 2) one at base of anal fin; 3) at end of tail near 
base of caudal fin there are two of which one is placed above, 
the other below medio-lateral line. 
Ånus behind middle of body, even in the smallest stages (abt. 
I cm in length). 
Paralepis (Sudis) hyalinus Rafinesque.
