DOUBTFUL SPECIES. 
TuE Gammarus nolens, Johnston (Zool. Journ. iii. p. 
179) has been referred to the present family, as a species 
of the genus Typhis of Risso, without sufficient founda- 
tion,* and probably in consequence of its supposed rela- 
tionship to Montagua monoculoides, which was mistaken by 
White and Gosse for a Typhis. Vide page 54, It is de- 
scribed as about three or four lines long, and not much 
compressed. The antenne are not more than one-third the 
length of the body, the superior pair being the shortest ; 
the first and second pairs of legs monodactyle ; the first 
with a small hand, the second with the hand more dilated ; 
the legs monodactyle and spinous; the two pairs of 
caudal processes having mucronate branches, and the 
middle tail-piece is simple, terminating in a papilla, 
without any terminal processes. 
It is described as not being rare near Berwick-upon- 
Tweed, and as inhabiting conferve, but we have not 
seen a specimen.
