Rostrum armed with ten teeth above, and one below ; a long spine 

 at the lower margin of the orbit ; first and second pair of hands with 

 fingers long and slender; the last joint of each leg 

 fringed with teeth ; and one stout hair curved in 

 a contrary arch, springing from the posterior ex- 

 tremity of the penultimate joint. 



This species was sent me by the Rev. G. Gor- 

 don, from Moray Frith, among other Macroura, 

 including P. Jeffreysii. The basal joint of the in- 

 ternal antenna) is developed on the inner side into 

 a squamiform tooth which reaches beyond the first 

 articulation. External antenna? with the tooth at 

 apex of squamiform scale, remote from upper ex- 

 tremity. Central plate of tail (telson) terminates 

 in a minute and central point. Three stout hairs 

 on each side. Lateral margin with two stout, 

 articulated, short spines. 6, exte^al antenna. 



The long and elegantly formed hands, and large d ' internal antenna, 

 si zc of second pair of feet, separate it from the other known British 

 species. 



I have named it after ,its discoverer, the Rev. G. Gordon, of Elgin.
