I 



Professor Tycho Tullberg, Director of the Univer- 

 sity Zoological Museum in Upsala, requested me in the 

 year 1890 to examine and treat the Leptocephalids to 

 be found in that Museum. 



At that time the collection embraced, firstly, a 

 number of specimens from the Straits of Messina, col- 

 lected by Professor Hj. Theel and Dr. A. Appelloe 

 during their stay at Messina in 1888, and secondly, 

 specimens from extraeuropean waters, obtained by 

 the late Captain G. von Soheele on his extensive 

 travels in tropical seas, especially in the Malayan 

 Archipelago. 



In the meantime Dr. C. Bovallius has enriched 

 the museum with a number of specimens obtained in 

 1891 by him in Italy; and the late Captain A. Fors- 

 steom has presenter! the Museum with some Lepto- 

 cephalids from the Atlantic' But it is to the late Cap- 

 tain G. C. Eckman that the collection is especially in- 

 debted for additions. He handed over to the Museum 

 a large number of specimens, which he had procu- 

 red in the Central Atlantic. 



At present the Museum contains 29 species of 

 Leptocephalids, of which there are in all 541 repre- 

 sentatives.
