B. Gabriel, JB. schles. Ges, Ivi. p. 120, is led by observation of Ore- 
garince in the Earth-worms to the belief that certain of these develop 
directly out of protoplasmic bodies, which represent Monera in sim- 
plicity of structure, thereby passing over the amoeboid stage, and are 
called by him primitive protoplasms. 
Robert, tom. cit. p. 139, has a short note on the Psorospermice of the 
Rabbit. 
R. Hallez figures, Travaux de Tlnstitut Zoologique de Lille, fasc. ii. 
p. 85, pi. V. figs. 26-33, various forms of Gregarines found in Planaria 
fuaca ; and mentions, 1. c. pi. v. fig. 34 & 35, some cysts visible to the 
naked eye, which are probably Psoroapermice^ and, p. 86, pi. v. fig. 36, 
some small amoeboid masses, possibly a transition stage of a Gregarina.
