Moniez, R. (1) Les nymphes de Rhabditis. Rev. Biol, iii, pp. 470-473. 
Leuckart watched the metamorphosis of Rhabditis coarctata, n. sp. [see 
Leuckart (2)]. The free-swimming Rhabditis fixed themselves on the 
Aphodius, became immobile, and the contents of the body detached them- 
selves from the cuticle and fused into a mass. A' moult then ensues. 
Author says he himself described this process two years ago.

i. Sur des larves de Tr&matodes qui se fixent & la surface de la coquille 
d 'Ostracodes d’eau douce et sur le corps des Hydrachnides. 
Author is inclined to assign the larvae which are encysted on the Ostra- 
cods , to the Distoma perlatum, Nordm., of the tench ; while he is unable 
to identify those on the Hydrachnids. It is probable that the develop- 
ment of the forms represented by these larvae is comparatively simple, 
without the intervention of Ccrcaricc , &c. 
il. Sur les Cysticerques des Ostracodes d’eau douce. 
Cysticercus of T. coronula occurs in Cypria ophthalmica and Candona 
Candida in north of France. Mrdzek has found it in Cypris ovum , Jur. 
Cysticercus of T. anatina in Cypris incongruens , from Lille ; and that of
