CRUSTACEA DECAPODA— BORRADAILE. 83 



L. reynaudi. I would poiut out, however, tliat the differences between these species 

 have not yet been wholly disposed of. Bate's specimens, which are quite faithfully 

 represented by the figure in the " Challenger" Report, still fail to agree with Kemp's 

 redescription (Linn. Trans, loc. clt.) of Dana's species. In them the last leg does not 

 nearly reach the end of the neck, and the latter is from once and three-quarters to 

 more than twice as long as the rest of the cephalothorax. The size of the specimens 

 makes it impossible for these discrepancies to be due to ditferences in age, but it is 

 quite possible that they may be accounted for by variation. In any case, however, the 

 matter needs further investigation. 



Numerous specimens of L. hatei were taken l:)y the Expedition at Stations 45, 46, 

 47, 50, 53, 61, 63, 64, 65, 66, 67, 68, and 126.

Specimens taken in the sub-tropical Atlantic by the Expedition evidently belong 

 to the species described by Faxon and Brooks from more northerly waters of the same 

 ocean. 



Twelve specimens were taken at Stations 39, 40.

Lucifer hanseni, Nobili, Bull. Mus. Paris, 1905, p. 394 ; Ann. Sci. Nat. Zool. (9), IV, p. 25,

Lucifer inermis, Borradaile, Ann. Mag. Nat. Hist. (8), XVI, p. 229 (1915). 



I regret to have altogether overlooked Nobili's papers in my recent enumeration 

 of the species of Leucifer. 



Numerous specimens were taken in Melbom'ne Harbour.

12. Pasijyhciea longispina, Lenz and Strunck, 1914. 



Pasiphaea longispina, Lenz and Strunck, Deutsche Siidpolar Exp. XV, iii, p. 315, pi. XIX. 



Lenz and Strunck's specimen was damaged. Those which were taken by the 

 " Terra Nova " enable me to add the following facts to the German authors' description. 



The rostrum slightly outreaches the eye, and has a sharp, downwardly hooked tip. 

 The length, in the mid-dorsal line, of the sixth abdominal segment equals that of the 

 telson, and is twice that of the second segment. The sixth segment has no spine 

 behind. The telson is little shorter than the sharp-tipped endopodite, and a good deal 

 shorter than the round-ended exopodite of the uropod. Its dorsal surface is deeply
