(Plate 5, fig. 3.) 



Several of this species were obtained, and I may note the form of the acicula, 

 of which two or three occur in each parapod. They may be colourless or brown, but 

 have a characteristic extremity. This is a rounded knob quite unlilce those of S. 

 closterobranchia (fig. 3). 



The uppermost chfeta, which is capilliform (" Nadel" of Ehlers), does not make 

 its appearance till about the 20th foot, and may even be absent from some of the 

 posterior feet, though whether they are broken or not developed I cannot say. 



Locality. — 



Macquarie Islands. Scrapings off kelp. 



Distribution. — Magellan, Kerguelen, South Georgia, Kaiser Wilhelm II Land 

 (Ehlers), Booth Wandel Island (Gravier), Falldand Islands (Fauvel).

 Ehlers ( 1913), p. 473, pi. XXXII, figs. 1-4. 



Several fragments of this Antarctic worm, consisting of the head and some 

 20 chsetigerous segments, were obtained. They measure 25 mm. in length and about 

 0-5 mm. across. Some are ripe females filled with eggs as far forwards as the 

 proventriculus, but they present no epitokous modifications. 



* It may here bo noted that, Fauvel (1917, p. 193) regards the variety of Si/Uis rlostrruhranchia from the Chatham 

 {slaiids (Ehlers), a specimen of which he has found on the coast of South Australia, as identical with jS. hyalina Grube,
