Material. 



The present paper contains the result of 

 helniinthological research work made in fishes 

 of our coast. However, it only embraces 

 those representatives of the genus Cuculla- 

 nus, which I was the first to describe. The 

 numerous fishes examined came not only 

 from the Bay of Rio de Janeiro, but also 

 from the Ilha Grande, an island to which I 

 made an excursion at the end of 1916. 



Cucullanidae B. BARRETO. In the year 

 1916, I added the new family Cucullanldoe 

 to the already existing families of Nemato- 

 des. 



Already in 1915, RAILLIET & HENRY, 

 when studying the genus Cucullanus MUEL- 

 LER, 1777, noticed the great confusion that 

 reigned amongst the different authors 

 from DUJARDIN onwards, about the repre- 



sentative genus Cucullanus and Docnltis, 

 DUJ., 1845. They came to the conclusion 

 hat the name Cucullanus MUELLER, 1777 

 ought to be given to the species then inclu- 

 ded in the genus Dacnitis DUJ., 1845, of 

 which the type is Dacnitis esuriens, DUJ. , 

 1845. This species was identified by SCHNEI- 

 DER with Cucullanus foveolatus, RUD., 1809 

 and Cucullanus cirratus, MUELLER, 1777 

 by RAILLIET and HENRY 



The genus of MUELLER is however 

 completely different from that to which DU- 

 JARDIN and after him all the other authors 

 gave the name Cucullanus, with Cucullanus 

 elegans ZEDER, 1800 as type species. It was 

 time to change the name of this last for 

 which RAILLIET & HENRY proposed the 

 name of Cucullanus. 



I am of the same opinion as RAILLIET 

 & HENRY who think that the Dacnitis 



(1) In 1913, RAILLIET & HENRY changed the sub-family Heierakinae into a family composed of five ge- 

 nera, amongst which is Dacnitis.
