Heterorhabdus austrinus, Giesbrecht. 
1902, Heterorhabdus austrinus, Giesb., Expéd. Antarct. Belge, ‘‘Copepoden,” p. 28, pl. vi. 
H. austrinus occurred in gatherings from 200 and 500 fathoms. Only one or 
two specimens were obtained. ‘These gatherings were collected on 2nd March 1908 ; 
Station 280, 68° 40’ S., 30° 18’ W.

A single specimen of this Haloptilus was obtained in each of two gatherings, in 
one from 200 fathoms, the other from 500 fathoms, collected on 2nd March 1903 in 
68° 40’ S., 30° 18’ W., Station 280. These specimens are more than twice the size 
of those recorded by Dr Girsprecut, and on that account were considered at first 
as belonging to a different species. A careful examination of them, however, did not 
reveal any difference sutticiently important to separate them from H. acutifrons.

This was a tolerably common form in the Scotia plankton collections, and appeared 
to be widely distributed. It was observed in samples collected at twenty-eight 
different stations, extending from Station 7 in 26° 23’ N., 20° 20’ W., to Station 
95: in 32° 15/.8., 47° 30) We

This Candacia was obtained sparingly in gatherings from the following five 
stations, viz. 31, 32, 35, and 49 in the North Atlantic, 11° 10’ N., 25° 20’ W., to 
1° 53’ N., 27° 26’ W., and Station 59 in 2° 30’ S., 32° 42’ W. This species is found in 
the Red Sea, and its distribution extends both to the Atlantic and Pacific Oceans.
