new or rare Crustacea from Scotland. 245 
superior antenne, the peculiar arrangement of the hairs at the 
base of the flagellum of the same antenne, the longer 
mandible-palp, and the form of the largely developed basal 
joint of the last pereiopods. 
As was pointed out by the Rev. Mr. Stebbing several years 
ago, there appears to be comparatively little difference between 
Cyproidia, Haswell, and Stegoplax, G. O. Sars. The only 
characters of any value that appear to separate the two genera 
are the apparent presence (Cyprotdia) or absence (Stegoplax) 
of a minute secondary appendage to the superior antennae, 
and the hands of the second gnathopods being larger than 
(Cyprotdia) or similar to (Stegoplax) the hands of the first 
enathopods ; the difference of length of the rostrum can only 
be of specific value. The Moray Firth specimen, in possessing 
mo secondary appendage to the superior antenne, agrees 
better with Haswell’s amended description than with that of 
the Rev. Mr. Stebbing, as well as exhibits a close affinity 
with Stegoplax.
