80 BRITISH COPEPODA. 



the first three *br four joints much thicker than the 

 rest, fourteenth and fifteenth joints the smallest, and 

 together about equal in length to the terminal joint. 

 The secondary branch of the lower antenna (fig. 12) 

 is much more slender than the primary, and is com- 

 posed of six small joints of nearly equal length. The 

 first pair of swimming feet are very small, and they, as 

 well as the following three pairs, have both branches 

 composed of three joints. The fifth pair of feet (fig. 

 15) are 1-branched, 3-jointed, the first joint broad and 

 short, the second somewhat narrower, but of about 

 the same length, the third longer and a little more 

 slender ; the first two joints each bear a stout apical 

 seta, the third three more slender setae. Last joints 

 of the abdomen very short, tail segments (fig. 16), 

 about as broad as long. 



I had until lately seen but one example of this 

 species, which was taken off Hawthorn (Durham 

 Coast) on a sandy bottom in a depth of 27 fathoms, 

 but while these sheets have been going through the 

 press I Lave found other examples in a dredging from 

 Portin cross (Ayrshire), and in washings of Laminaria 

 roots from Mulroy Lough (Donegal). It would appear 

 to be of rare occurrence, as M. Boeck also had met 

 with only one specimen. Though placed by that 

 author amongst the Cyclopidse, I prefer to associate 

 Misophria with Pseudocyclops and Cervinia as a 

 distinct family. These genera must be looked upon 

 as transitional forms occupying a position between 

 the families C'alanidce and Cyclopidce. There are 

 some slight discrepancies between the description
