AUSTRALASIAN ANTARCTIC EXPEDITION. 
Just as there is a variety of H. spin os a (Lagisca antarctica or L. vesiculosa), so 
here we have a variety of H. tuberosa, differentiated by the great size of the tubercles ; 
but here they are conical, rather than spherical, and recall those figured by Kinberg 
for H. pat agonic a (1857, pi. V, fig. 22 H). 
Localities .— 
Boat Harbour, winter quarters, Station A, fathoms (one individual). 
Station B, 25 fathoms (fifteen). 
Station C, Commonwealth Bay, 15-20 fathoms (one). 
Station D, 45-50 fathoms (one). 
Station E, 55-60 fathoms (two). 
Station 1, 350-400 fathoms (one). 
Station 3, 157 fathoms (one). 
Station 8, 120 fathoms (two). 
Distribution .— S. Victoria Land; Bouvet Island (Elders). 
Harmothoe abyssorum McIntosh. 
Eunoa abyssorum McIntosh (1885), p. 73, pi. XI A, figs. 14-16. 
(Plate 6, figs. 30-35.) 
Three specimens of this species were obtained, and as the type was dried up, so 
that McIntosh was unable to say much about its anatomy, an opportunity occurs of 
adding to that brief account. 
The largest of them is 29 mm. long, with 35 segments, but is imperfect. It is 
broadest at about segments 7-12, thence tapering. Here it measures 5 mm. across 
the body, 10 mm. over the parapods, and 12.5 mm., including the chsetse. At segment 
20 these numbers are 3 mm., 6 mm., and 9 mm. respectively, so it is clear that only 
a few segments are missing. 
The ventral surface of the body is purplish, darker posteriorly, and the pigment 
extends on to the feet, where, however, it becomes fainter. The dorsum is devoid of 
pigment. 
There aie fifteen pairs of elytra, which are present on one of the smaller 
individuals. I hey are colourless, translucent, and rather thick, but towards the 
external marg.n they become slightly yellowish and opaque. They are smooth not 
only to the naked eye, but even microscopically, except that over the outer area there 
are numerous minute, rounded refringent tubercles, which seem to be the cause of the 
yellowness here (fig. 33). 
The prostomium (fig. 30) is broad, with well-developed peaks on the outer side 
of the bases of the lateral tentacles; both pairs of eyes are on the dorsal surface, and 
lie behind the middle of its length. The two eyes of one side are thus close together,
