The species is chiefly characterised by the sliortness of its eye- 

 stalks, and the great reduction of the cardiac area of the campace. 

 It is apparently allied to P. setosus, a species from New Guinea, 

 insufficiently described by H. Milne-Edwards, but if Ortmana (Zoolo*'-. 

 Jahrb., Bd. vi., Abth. f. Syst., p. 281, taf. xii., fig. 9, 1892) is correct ia 

 his identification of the latter, the two are distinct. The species 

 figured by Ortmann has slightly longer eye-stalks, a longer antennal 

 acicle, and an entirely different configuration of the cardiac area of 

 the carapace ; in his description there is but slight reference to the 

 other characters. According to Milne-Edwards the colour of his 

 species was reddish yellow.

Station 150, off the north Maldive Atoll, depth 719 fathoms. An 

 adult male in a shell of Bathyhemhix woodmasoni, E. A. Smith, invested 

 by an anemone. 



The anterior portion of the carapace is moderately convex, both 

 from side to side, and from before backwards ; the surface is slightly 

 uneven, with a few tufts of hair near the lateral and anterior margins. 

 The median frontal projection is fairly prominent, while the lateral 

 projections are scarcely indicated at all. The portion of the carapace 

 behind the cervical grooves is membranous, and even the cardiac area 

 is uncalcified. The eye-stalks are slightly concave on their inner 

 surface, and a few rather long hairs are found on the upper surface 

 of each ; the corneae are small, but deeply pigmented. The ophthalmic 

 scales are small and laterally compressed, each terminating in four 

 small apical denticles. The antennal peduncles are broad, and exceed 

 the eye-stalks by about the length of the last peduncular joint ; the 

 acicle has a slight sigmoid curve, and extends to the end of the 

 peduncle, while its inner margin is provided with a row of spinules. 

 The external prolongation of the second joint of the antennal peduncle 

 is acute, but very short ; the terminal joint of the peduncle is broad, 

 and flattened from above downwards. The antennal flagellum is more 

 than twice the length of the body. The antennular peduncles exceed 

 the eye-stalks by the whole of their terminal joint, and about two- 

 thirds of the length of their penultimate joint. 



The chelipedes are elongated and slender, with the joints faintly 

 pubescent, and armed with subspiniform granules. The carpus is about 

 one-fourth of its length longer than the merus ; it is practically cylin- 

 drical, and the whole surface is uniformly granulated, but the granules 

 or spinules as they might almost be termed, are most marked on the
