the abdomen in length, and so different from that of Branchipus 

 (B. stagnalis) that I cannot doubt of the generic distinctness of 

 Branchinecta. The terminal joint of the claspers in the female 

 is very much abbreviated. The external male genital appendages 

 are slender, and armed with a curved spine-like fleshy process 

 near the base.

Several specimens, including both males and females, were taken 



from a species of Cod caught by line in 100 fathoms in the North 



Sea in lat. 58° 53' N., long. 1° 2' E., and, unlike the Laphjstius 



slurionis, occurring on the same fish, this species was distributed 



over the whole body of the animal.

Three specimens were obtained in the rich haul off Hare 



Island, and two were taken from the " Greenland Shark " at 



Umenak. Mr. "Whymper notes that they are usually, but not 



always, found attached to the eyes of the fish. The specimens are 



in fine condition.
