Temora turbinata (Dana). 



1849, Cnlanus turbinatus, Dana, op. tit., vol. i. p. 12. 



1892, 'I'emora tiirliimitu, Giesb., op. cit., p. 329, pi. xvii. fig. 14 et seq. 



The only two samples in which this species was observed were collected at Station 

 12, 22 19' N., 22 07' W., and Station 14, 21 28' N., 22 40' W., both in the North 

 Atlantic. 



Fam. METRIDIID^E. 

 Genus Metridia, Boeck, 1864. 



Metridia lucens, Boeck.

A number of specimens were obtained in one or two samples collected on the 4th 

 and 5th of May 1904 off Cape Peninsula, South Africa, Station 476, 34 43' S., 17 15' E., 

 and Station 477, 34 21' S., 18 29' E. The Eev. T. E. E, STEBBING records the species as 

 " abundant south and west of Cape Colony " (Annals of the S. African Museum, vol. vi. 

 pt. iv. p. 535, 1910). 



Metridia gerlachei, Giesbrecht. 

 1902, Metridia gerlachei, Giesb., Exped. Anfarct. Beige, " Copepoden," p. 27, pi. v. 



This species was obtained in two gatherings, in one from 200 fathoms collected 

 on 28th February 1903 in 69 22' S., 26 36' W., Station 273; and the other from 

 500 fathoms collected on 2nd March in 68 40' S., 30 18' W., Station 280. 

 The distribution of Metridia gerlachei is apparently limited more or less to deep 

 water, for although it was obtained at a number of stations by the Belgian Antarctic 

 Expedition of 1897-1899, none of the samples in which it occurred were surface 

 gatherings, but were from depths ranging from 100 to 500 metres. 



Genus Pleuromamma, Giesbrecht, 1898. 

 Pleuromamma abdominalis (Lubbock). 



1856, Diaptomus abdominalis, Lubbock, Trans. Entoni. Sac. Land. (N.S.), vol. iv. p. 22, pi. x. 



The only gatherings in which this species occurred were collected at Stations 26 and 

 56, the one in 14 33' N., 25 09' W., Station 26, and the other in lat. 42' S., long. 

 31 20' W., Station 56 ; very few specimens were observed. 



Pleuromamma gracilis (Glaus). (PI. XIII. fig. 7.) 



1863, Pleuromma yracilis, Glaus, Diefreilebenilen Copepoden, p. 197, Taf. 5. 



This species was only observed in gatherings collected at Stations 14, 18, 39 ; all 

 in the North Atlantic, 21 28' N., 22 40' W., to 6 43' N., 25 48' W.
