ENTOMOSTRACA OF THE SCOTTISH NATIONAL ANTARCTIC EXPEDITION. 587 
Fam. HaLocyprip&. 
The Halocypride being for the most part pelagic in their habits, are widely 
dispersed throughout the Atlantic, Pacific, and Indian Oceans, but appear to be more 
frequent in tropical regions. The species recorded here are chiefly from these regions, 
and were collected by the s.y. Scotva on the outward voyage to the Antarctic; no 
Halocypridze were observed in the collections from the South Orkneys.

This species was obtained in gatherings from Stations 21, 26, and 59, the first 
m 18° 28’ N., 24° 28’ W., the last in 2° 30’ &, 32° 42’ W. The specimen 
represented by the drawing measures 1°65 mm. ‘The species is widely distributed 
in the Atlantic, the Pacific, and Indian Oceans, and appears to be subject to some 
amount of variation, and has been described under several names (cf. G. W. MULLER, 
op. cit.).

H. globosa was obtained in a gathering from Station 16, 20° 29’ N., 
23° 16’ W., collected 29th November 1902. In this species the shell has a short 
rotund form; seen from the side, the dorsal margin is flattened, but the lower is 
boldly arched in the form of a semicircle, the depth across the middle being equal to 
about four-fifths of the length. The specimen represented by the drawing (fig. 32) 
measured °85 mm.

This widely distributed species occurred in surface gatherings from Stations 14, 16, 
and 59; the first in 21° 28’ N., 22° 40’ W., the last in 2° 30’ S., 32° 42’ W., collected
