Tliis species resembUis J'inrdlauo-pai/imiti edwardnii, Filliol,* 

 but it differs from Filhul's species in niiiiiy cliaracters, of which 

 the following are tlu; most noticeable : — The unecjual clu^he, the 

 prominent external denticles of the front, the less prominent 

 lateral teeth of the anterior sides on the carapace, and the weaker 

 character of the armature and sculpture of the ambulatory legs. 



The fifth pair of legs in P. edwardsii is represented as chelate, 

 but I failed to find any such character in the example under notice. 

 When viewed under the microscope with transmitted light, the 

 propodus is seen to terminate in two rounded denticulated lobes, 

 one about as long as broad, and the other twice as long as broad ; 

 the latter probably represents the tarsus, but there is no trace of 

 articulation at its base. 



Two males of this rare and curious form were obtained off 

 Wata Mooli, in 54-59 fathoms.

Station 44. 



Two examples of this species were obtained off Bondi. The 

 larger specimen has a parasite attached to the lower surface of 

 the abdomen — probably a species of Rhizocephala. The " Chal- 

 lenger " examples were infested with a similar form. 



The specimens differ considerably from the description and 

 figure given by Henderson. The rostrum is slightly depressed, 

 about 1 mm. long (measured from the lateral spines at the base), 

 and 0-8 mm. wide, the sides gradually sloping to a pair of smaU
