(Hodgson). 
Leionymphon australe, Hodgson, 1907, p. 46, PI. vii, fig. 1. 
Ammothea australis, Bouvier, 1913, p. 123. 
Occurrence. —Station 331, Entrance to McMurdo Sound, 250 fathoms; 1 $. 
Station 338, Entrance to McMurdo Sound, 207 fathoms ; 1 $. Station 340, off Granite 
Harbour, 160 fathoms; 1 h 1 young. Station 356, off Granite Harbour, 50 fathoms ; 
1 young. 
Remark*. —The specimens agree closely with syntypes of the “ Discovery ” 
collection and differ from specimens, which 1 refer to A. claus'd, from South Georgia 
and the South Sandwich Islands, in having the abdomen obliquely set and separated 
by a short interval from the articulation between the last two trunk-somites, the apex 
of the ocular tubercle rounded with a small central spike instead of conical, and the 
setse of the body and limbs less numerous. The spinous character of the young, 
referred to by Mr. Hodgson, is noteworthy.

Description.—Lateral processes (except the last two pairs) separated by intervals 
much less than half their own diameter. Transverse body-ridges prominent, rising in 
the middle line into acutely conical processes. Cephalon wider than long, contracted 
behind, with a pair of spinose tubercles over the bases of the ehelophores. Paired
