﻿COPEPODA i,c 



Y^ (St. V). Size of specimen from Thor St. 88 was 3-16 111111.; anterior division 251 mm.; uro.some 

 0-65 mm. 



Ill the .shape of the body etc. it is scarcely different from the adnlt female, bnt the lateral 

 corner of the thorax is more pointed, sho\vin_>f, however, a similar difference between a more pointed 

 left and a more rounded right corner. In one of fi\'e females a strong spine, similar to that of the adult, 

 directed upwards and slightly backwards was found dorsally near the posterior margin of the first ab- 

 dominal somite on the right side; in two other specimens the spine was represented by a single tooth, or 

 a few only; along the posterior margin of the second abdominal somite no short teeth were fonnd. The 

 appendages are in the main like those of the adult females; the Re of the ina.xillnlae po.s.scss as usual 

 only 10 setae, of which the median are the shortest; the Se of Re II pes I is shorter than in the adult 

 female, but longer than in the adult male, reaching somewhat beyond the middle of the following seg- 

 ment. The male is always easily distinguished from the female by the presence of a rather short and 

 clumsy ////// pair of legs, of which the left is the longer (text-fig. 35 g). 



Occurrence. The Iiigolf E.xpedition has taken 2 females, of which one with spermatophore.

Distribution. This species seems to have a world-wide distribution. It has been recorded from 

 the warm area of the Faeroe-Shetland channel, from the west coast of Ireland as far north as 54° L. N. 

 "at depths of from 400 to iioo fathoms". It has been taken by the Monaco Expedition and by the 

 Gauss Expedition in the Mid- and South Atlantic as far south as 35° L. S. By the Siboga Expedition 

 it was found rather common in the Malay Archipelago; it was recorded by Giesbrecht from the 

 Pacific (6°20 L. N. 166 — 173 L. E.) and by Esterly from the Bay of California. 



Remarks. In spite of a few minor differences I am fairly convinced that this species is identical 

 with that described by Giesbrecht. Though Scott's fig. 8 PI. XXII is wanting in details I think his 

 male is identical with that described here. Scott is possibly right in identifying Lubbock's I'/uiina 

 plninosa with this male, in .spite of minor differences, especially in the structure of the right filth foot, 

 which may, however, be due to a mi.stake; as Lubbock's description is rather incomplete, I do not at 

 present accept the name U. plniiiosa. 



I think Scott is right in referring the female of Brady's Eiiclurte pnlchra Lubb. to U. iiiiuor. 

 As far as I understand Scott, he refers Brady's Evcli(rtc pulclira^ and his E. ausiralis '^ to the same 

 .species, but when we coini)are Brad>'s fig. 5 PI. 21 ami fig. 6 PI. 14, it is ea.sily realised that the two 

 animals are probably not identical, especially on account of the different shape t>f the genital somite. I
