are a few little stiff setee, such as are arranged in lines on the 
fingers of all the ambulatory limbs, but only the penultimate 
joint of the fourth legs shows a trace of the felting. 
The dimensions and localities have been already mentioned. 
Dr. Ortmann’s specimen was nominally from New Zealand, 
but he warns the reader that the habitat assigned could not be 
entirely trusted.

Alcock’s definition is as follows :—‘‘ The front is cut into 
lobes or teeth by the antennular fossae, which are visible in a 
dorsal view as deep clefts ; the lower border of the orbit curves 
down into line with the prominent anterior border of the buccal 
cavern ; the external maxillipeds do not completely close the 
buccal cavern, but they do not leave a wide rhomboidal gap, 
they are not traversed by any oblique hairy crest, their palp 
articulates near the antero-external angle of the merus, and 
their slender exposed exognath has no flagellum. The antennal 
flagella are short. The male abdomen fills all the space between 
the last pair of legs.”
