orbitse. Chelae ad primum et pedarum secundum paria digitos longos 
et graciles habent. Dactyla ad pereipoda et posteriores cum dentibus or- 
natis. 
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 antennae is developed on the inner side into 
a squamiform tooth which reaches beyond the first 
articulation. External antennae 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. 
The long and elegantly formed hands, and large 
size 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.
