THE PTEROPODA 



who, (luring the years 1878 — 1880, collected some species, 

 also by means of surface nets, in the Atlantic and In- 

 dian Oceans. 



Furthermore it may be remarked that only Euthecosomata 

 (in the sense of Meisenheimer) are fairly well represented, 

 while Pseudothecosomata (Cymbuliidae as they are generally 

 called) and Gymnosomata are almost wanting ; and to my 

 great regret I can contribute scarcely anything to the 

 distribution of these small, but most interesting groups.
