Gammarus puteanus (Koch). P. de Rougemont, Naturges. Gamm. 
[^suprd, p. 2] pp. 26-40, from observations made at Munich and Neu- 
chatel, comes to the conclusion that this animal is able at a very early 
stage to produce eggs, even when it has attained no more than one-tenth 
of its maximum size, but that it undergoes considerable transformations 
by subsequent moults. He distinguishes the following 5 forms, or stages 
of development, all of them being found in the same well at Munich : — 
I. G. minutvs (Gervais) = Crangonyx suhterraneus (Bate) ; ll. Ni- 
phargus hochianus (Bate) ; III. G. puteanus (Caspari, Hosius) = N. 
fontanus (Bate) ; iv. G. puteanus (Koch) ; v. N. stygius (Schiodte) 
= G. puteanus (Lavalette, Plateau) ; vi. a very large specimen, 85 mm. 
in length, including the antennae and caudal appendages, the body alone 
33 mm. The differences are situated chiefly in the appendages of the post- 
abdominal segments and in the development of the prehensile hand. 
He thinks therefore that the genera Niphargus and Crangonyx are to be 
cancelled.
