1892, Temora turbinata, Giesb., op. cit., p. 329, pl. xvii. fig. 14 et seg. 
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 m the North 
Atlantic.

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° 43’8., 17° 15’ E., 
and Station 477, 34° 21’S., 18° 29’ E. The Rev. T. R. R. Srepsine records the species as 
“abundant south and west of Cape Colony” (Annals of the S. African Museum, vol. vi. 
pt. iv. p. 535, 1910). 
Metiidia gerlachei, Giesbrecht. 
1902, Metridia gerlachei, Giesbh., Hapéd. Antarct. Belge, ‘‘Copepoden,” p. 27, pl. v. 
This species was obtained in two gatherings, in one from 200 fathoms collected 
on 28th February 1903 in 69° 22’ 8, 26° 36’ W., Station 273; and the other from 
500 fathoms collected on 2nd March in 68° 40’ §., 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. Kntom, Soc. Lond. (N.S.), vol. iv. p. 22, pl. 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. 0° 42’ S., long. 
31° 20’ W., Station 56; very few specimens were observed. 
Pleuromamma gracilis (Claus). (PI. XIII. fig. 7.) 
1863, Pleuromma gracilis, Claus, Die freilebenden 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.
