Alciopidcs. 
Clapar^de & Panceri describe (1. c.) a larval form of an Alciope found living 
in the external tissues of Cydippe densa, Forsk. The development of these 
forms was traced from a stage when the head was not distinct from the body, 
when there was no vestige of cephalic appendages, and no indication of the 
division of the body into segments, and when it was provided with cilia. The 
largest larval forms examined were from 6 to 10 millims. long, and were found 
in the stomachs of the Cydippe j and the authors Suggest that the Cydippee\i\\et 
swallows the ova of the Alciope or that the young Alciope penetrate into the 
substance of the Cydippe. In either case, the fact of their endoparasitism 
is the same ; and though it may seem strange that so highly developed a form 
ns Alciope should be parasitic, yet may it not be that this is so, to en- 
able the eyes and feet to have time, as well as favourable conditions, in 
which to develop and grow. Although it is not possible to assign such 
larval forms to any known genus of this family, yet as it can be even now 
determined that there are four antennse and two tentacles of the oral seg- 
ment, and that the first three pairs of feet differ from the rest, there can be
