o8 AUSTRALASIAN ANTARCTIC EXPEDITION. 



Remarks. — Gravier points out certain differences that exist between his species 

 and P. longicinata Greef. Unfortunately I have not access to Greef's paper, 

 as the vohune 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 eual)le me to judge of Gravier 's 

 statements in this respect. 



The only figure relating to tlie species, wliich is available to me, is that 

 given by Southern (1909, pi. I, fig. 1) of the chteta; and his statement on 

 p. 2, that the appendix of all the chaetse has " on the posterior side a delicate 

 wing-like expaiLsion." 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 entii-e, 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.
