AUSTRALASIAN ANTARCTIC EXPEDITION. 
Remarks.- Gravier points out certain differences that exist between his species 
and P. longidnata Greet. Unfortunately I have not access to Greef’s paper, 
as the volume is missing from my series of the Zeit. f. Wiss. Zool. And, 
although the species has been recorded from most of the Antarctic expeditions 
no details or figures are published that enable me to judge of Gravier’s 
statements in this respect. 
The only figure relating to the species, which is available to me, is that 
given by Southern (1909, pi. I, fig. 1) of the cliseta; and his statement on 
p. 2, that the appendix of all the chaetse has “ on the posterior side a delicate 
wing-like expansion.” This is certainly not present in the species before me, 
and, moreover, the length of the appendix is longer and slenderer than it is 
in that figure, and is in entire agreement with Gravier’s figure.

My excuse for describing once again this Antarctic species is that Gravier has 
thrown doubts on its generic position, and that the previous accounts are imperfect 
in some respects. 
The material obtained consists of two specimens, a male and a female, which 
were captured on the surface of the sea by Dr. A. L. McLean; and some smaller individuals 
from 45 fathoms. 
Dr. McLean notes that they are “ transparent, mottled with brown.” The 
female is entire, measures 135 mm. in length, its greatest breadth is 5 mm., at about 
mid-body. There are 93 segments, followed by a short regenerated region, 4 mm. in 
length, of very small segments. 
The prostomium is 3 mm. across, and the anterior part of the body is very 
narrow, only 1-75 mm., the head and this narrow region, or “ neck,” occupy a length of 
11 mm.
