 mud, and off Fairland Point, Cumbrae, in 20 fathoms. 



In the former Catalogue this species was pre-

 jilace of capture.

Habitat. Dredged on north side of Little Cumbrae, 

 in 20 fathoms, gravelly mud. 



The species of this genus appear to be very 

 closely related. Hansen, Overs. Dijmphna- Togtet 

 inds. Krebsdyr, p. 229, supposes that possibly Boeck's 

 species is not the same as that of Goes. In the 

 specimen examined, the iinier plate of the first 

 maxillae is surmounted by seven setae, the third joint 

 of the second gnathopods is produced to a sharp 

 point, and the first joint of the fifth peraeopods has 

 the lower hinder angle a little produced. These 

 points seem to distinguish the species from Boeck's 

 Melphidippa longipes, which has recently been shown 

 to be Melphidippa macra, Norman 



MELPHIDIPPA MACRA, Norman.
