CANTHOCAMPTUS.

foot-jaws consist, as in the preceding species, of two 
articulations, and a tolerably strong hook, which points 
upwards. 
The first pair of feet (t. XXVII, f. 3 a) has the ex- 
ternal or superior stalk much smaller and shorter than 
the other, and is divided into three joints, the last of 
which is terminated by three rather strong setae, or small 
hooks. The internal or inferior stalk is much the longer 
of the two, and is composed of two articulations, the first 
being very long in proportion to the second, which is ex- 
ceedingly short, and terminated by a curved hook. The 
three succeeding pairs of feet are precisely similar to 
those of C. minutus. The fifth pair is rather larger than 
in preceding species, and is formed of a broad, flat body, 
which is rounded at one side, and furnished with several 
rather long and finely-serrated setae; the opposite side 
giving off an appendage, provided likewise with setae 
serrated on their edges. 
When I first noticed this species, I considered it as the 
Cyclops brevicornis of Midler, w T ho professes to take the 
species from Strom, in the ‘ Acta Hafniae,’ * and who, 
among other characters, describes it as “ setis caudae 
brevissimis” Upon referring afterwards, however, to 
Strom’s paper, and finding his description of it as “ setis 
caudae lonyissimis” I gave it the name of Cyclops Strornii, f 
and having since that seen the figure he gives of the 
species he describes, I have no doubt of this being quite 
distinct.
