56 AUSTRALASIAN ANTARCTIC EXPEDITION. 



The parapods (fig. 54) are very short and rather high, the foliaceous dorsal 

 cirrus is long and narrow ; its length is more than twice its width ; its apex is 

 symmetrically pointed, its base is short and springs from the chsetigerous lobe close to 

 the body. The ventral cirrus is comparatively large and of similar shape, longer than 

 the chaetigerous lobe. 



The chaetse (figs. 55, 56) are comparatively few in number; the lip of the 

 articular cup is finely serrated on one side, smooth on the other; and the two lips are 

 approximately of equal height ; the appendix is long, narrow, straight, flexible and 

 tapers gradually to a fine point ; its edge is finely serrated. 



The pharyngeal apparatus was everted in the larger of the two specimens, though 

 the buccal membrane or pharyngeal sheath is ruptured at its base. The length of the 

 pharynx is 15 mm., with a diameter of 3 mm. at its anterior end. The aperture is 

 surrounded by 24 rather large papilla?, set as usual at the ends of ridges leading into 

 the interior. The buccal membrane is uniformly covered with closely-set unequal, 

 flattened, club-shaped papilla?, giving it a velvety appearance (fig. 57). They are 

 much smaller than those of the preceding species. 



From a study of the other specimen it appears that the intestine commences at 

 about the 34th segment, so that the buccal and pharyngeal regions together must be 

 10 mm. in length. 



Locality. 



Commonwealth Bay, Station 1, 350-400 fathoms. 



Remarks. I suspected that this worm was E. magalliaensis , the only specimen of 

 the genus hitherto recorded from these latitudes, but from it the present worm 

 differs in the larger eyes, in the position of the median tentacle ; in the much 

 greater length of the tentacular cirri ; in the form of the appendix, and 

 in the character of the articular cup ; and in the number and shape of the 

 pharyngeal papilla?. 



Genus ETEONE Savigny. 

 ETEONE REYI Gmvier. 



Gravier (1906), p. 26, pi. Ill, figs. 24-26; (1911), p. 60. 

 Ehlers(1913), p. 457. 



A single individual of this small Phyllococid was found on a slide on which I 

 had mounted some Syllids collected in Commonwealth Bay. 



It is but 5 mm. long, and consists of head, 26 chsetigerous segments and the 

 anal segment. 



I find that the prostomium differs from Gravier's figure in that it is produced 

 forwards as a narrower plate than the basal oculiferous region. This I take it is 

 what Ehlers means when he says that his specimen has a " spatelartig " prostomium.
