Schneider’s diagnosis is as follows : 
Pelodera Pellio. 
Seitenmembran, Haut sehr dick, Mund, Vestibulum und OEsopha- 
gus ganz Wie bei P. papillosa. Schwanz des © kegelfôrmig spitz. 
Bursa ganz wie bei P. papillosa. Keïne Drüsen am Vas deferens. 
Von Linstow regards the Anguillula lumbrici Gmelin (1)as a syno- 
nyme of this species, the description given by Diesing is hardy 
explicit enough to permit of identification. It is possible that 
Lieberkühn refers to the same species in his account of the Évolu- 
tion des Grégarines (2). 
2, — ASCARIS SP. 
In his « Die Menschlichen Parasiten » the late Professor Rudolf 
Leuckart describes a form of 4scaris which lives, not encapsuled 
but freely within the muscle fibres of the Mole. This Ascaris has a 
well marked boring tooth and it is to be recogniged also in the 
contents of the Mole’s stomach amongst a mass of fragments of 
half digesled Earthworms and Insect larvae. Leuckart points that 
Earth worms are infested by Nematodes of the same size and shape 
and provided with a similar boring tooth and he surmises that the 
Earthworm is the original home of these young Ascarids. When 
eaten by a mole the young Nematodes of the Earthworm are said 
to be quickly destroyed in the stomach of the Insectivore. When on 
theother hand the infected Moles’ flesh was given to a young Buzzard 
to eat, the lungs and liver of the latter became covered with tuber- 
cles containing the young Ascarids apparently still in the same 
state of larval development as when they were in the muscles of 
the Mole ! The whole question of this form seems to require rein- 
vestigation. 
3. — Disceuis riLaRIA Dujardin (3). 
This genus was established by Dujardin for the reception of a 
single species of Nematode which he found frequently in the 
« testicules » of Earthworms taken in his garden at Paris in the
