in the first pair in Psewdotachidius coronatus the inner are 
longer than the outer branches. 7 
The second, third, and fourth pairs are somewhat similar to 
the same appendages in Pseudotachidius coronatus; figure 7 
represents the fourth pair, and the second and third do not 
appear to differ very greatly from this. 
The fifth pair also resembles the fifth pair of the species 
referred to, but the armature is somewhat different, and there 
appears to be no distinct secondary joint (fig. 8). | 
The furcal joints are very short. 
No males were observed. 
fiemarks.—The species just described may be distinguished 
from Pseudotachidius coronatus, T. Scott, the only other member 
of the genus, by the difference in the structure of the antennules, 
by the inner branches of the first pair of thoracic feet being not 
longer than the outer branches, and by the difference in the 
armature of the fifth pair. 
This was one of the rarest of the copepods obtained from the 
piece of wood already referred to, and only a single specimen — 
was observed.

We owe the discovery of this interesting species to the 
Rev. A. M. Norman, who captured three specimens at Oban in 
July 1877, while dredging there t. Cervinia Bradyi appears to 
be a scarce species, for although, subsequent to its discovery at 
Oban, it has been found in a few other places in Britain, it has 
never occurred but in single, or at most few, specimens.at one 
time. ‘This, like the last, was rare in the material washed from 
the perforated wood. |
