16 AUSTRALASIAN ANTARCTIC EXPEDITION. 
Family KUCALANIDA. 
Genus RHINCALANUS Dana, 1852.

There are no points of difference, so far as appears from the published descriptions 
and drawings, between the species named above. The feet of the fifth pair in the 
female (Plate I., fig. 7) are quite characteristic, and, so far as I know. are unlike those 
of any other species. 
Drawings of some of the more interesting details of the male animal are here 
given. The head and rostral filaments are rather deeply pigmented, and in one of the 
specimens there is a circular black pigment spot in the median line at the back of the 
head. The proximal joints of the anterior antennee—at least seven or eight of then— 
bear club-shaped sensory sete as well as fascicles of branched and simple hairs. The 
outer branch of the posterior antenne is eight-jointed, nodose, and is much the shorter 
of the two branches. The foot of the right side in the fifth pair is simple, three-jointed, 
with a very long falciform apical claw near the base of which are two or three short 
spine-like seta; the foot of the left side consists of a stout basal joint, from which 
spring a bi-articulate endopodite and a single-jointed exopodite, both of which are finely 
setiferous; the abdomen is 4-articulate. 
R. gigas occurred plentifully in gatherings from the following Stations :— 
7, 8, 9, 13, 14, 16. | 
Three or four specimens of more than the usual size were also found washed up 
on a sandy beach after a storm at Macquarie Island. 
2. RHINCALANUS CORNUTUS Dana. 
Rhincalanus cornutus Dana, 1852, p. 1083, plate 77, figs. 2-a-d.

" Giesbrecht 1893, p. 153, plates XII and XXXYV. 
Two examples only of this species were observed, from Stations 14 and 16.

1. PARACALANUS PARVUS Claus. 
Calanus parvus Claus, 1863, p. 173, plate XXVI, figs. 10-14, plate XXVIT,—

Paracalanus parvus, G. O. Sars, 1901, p. 17, plates VIII and IX, 
Fairly common at Stations 8, 13, and 18, and almost the only recognisable species 
a gathering from Carnley Harbour, in the Auckland Islands—-Station 17.
