DISCOVERY REPORTS 



Conchoecia obtusata Sars var. antarctica Miiller. 



For description and synonymy see Skogsberg, 1920, p. 647. 



The species occurred in moderate numbers at Stations WS 976, 977, 996, 997 and 998. The pre- 

 viously recorded range of distribution of the species was in the Atlantic from 53 S. (Skogsberg, 1920) 

 to 26 S. (Miiller, 1906). The present records thus extend the distribution in the Benguela current 

 further north to 22 39' S. Miiller (1906, p. 149) considered that although the variety is typically 

 Antarctic in its distribution its range is extended northward by the cold Benguela current. The 

 present records are not then surprising.

Moderate numbers of this species were present in the samples from Stations WS 976-8, 986, 

 996 and 997. 



Conchoecia symmetrica Miiller. 



For description and synonymy see Skogsberg, 1920, p. 719 and figs, cxxxviii-cxliv. 

 Moderate numbers were present in samples from Stations WS 976-8, 986, 996 and 997. 



Halocypris brevirostris (Dana). 



For description and synonymy see Skogsberg, 1920, p. 584; figs, cxn-cxv. 



A single juvenile of this species was found in the sample from 250-100 m. at Station WS 997. 



Cypridina sp. 



A single unidentified juvenile of the genus Cypridina was found in the 250-100 m. sample from 

 Station WS 978. 



DISTRIBUTION OF SPECIES 



Owing to the wide range of variables involved in the present limited series of samples available, it is 

 not yet possible to interpret the distribution of species fully. As Fowler (1909) has pointed out there is 

 an almost hourly variation in the distribution of Ostracods. Some numerical data are, however, worthy
