4 DR. T. SCOTT ON COPEPODA 



in tlie first pair in PseudotacJiidius coronatus the inuer are 

 longer than the outer branches. 



The second, third, and fourth pairs are somewhat simihir to 

 the same appendages in Pseudotacliidms 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 sj^ecies 

 referred to, but the armature is somewhat difterent, and there 

 appears to be no distinct secondary joint (fig. 8). 



The furcal joints are very short. 



No males were observed. 



Bemarhs. — The species just described may be distioguished 

 from Pseudotacliidius coronatus, T. Scott^ the only other member 

 of the genus, by the difference in the structure of the antennulea, 

 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 

 xas observed.

We owe the discovery of this interesting species to the 

 Eev. A. M. Norman, who captured three specimens at Oban in 

 July 1877, while dredging there f. 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.
