DISCOVERY REPORTS 



St. 57. 16. V. 26. Port William, East Falkland Island. 52 cables S 20° W of Sparrow Point. 

 15 m. Gear BTS. Four specimens. 



St. 63. 22. V. 26. 48° 50' 00" S, 53° 56' 00" W. om. GearNH. " From floating M«fraf>'^/w." 

 Four specimens. 



Remarks. The four specimens from St. 63 measure 10-14 nim. by i mm. including 

 the feet and are in the "Chain" phase. 



The head and its appendages are well figured by Ehlers, the ist dorsal cirrus being 

 longer than the tentacular cirri. The dorsal cirri are very short and rather thick and the 

 second tooth of the chaetal blades is longer than the first. The pharynx runs straight 

 from the ist to 3rd chaetigers : in the 3rd it loops backwards alongside the proventriculus 

 into the 4th chaetiger: the proventriculus extends from the 3rd to the 6th chaetigers. 

 At the 14th chaetiger the stolon begins and is marked by a head in different stages of 

 development in the various examples. In the most highly developed there are two 

 pairs of brown eyes, a pair of forked palps, a median and two lateral tentacles. Behind 

 the head in the largest stolon there are about 45 chaetigers. The stolon seems to show 

 no differences from the stock except that the constrictions between the segments are 

 more marked. In the less developed specimens the head of the stolon appears as a 

 white pad of tissue across the 14th chaetiger. There are no traces either of swimming 

 bristles or oi Ehlersia bristles. There is never more than one individual behind the stock.

Description. A single example tightly curled round a cluster of eggs. The eggs are 

 very numerous and small, and the brood pouch is not visible, but the firm line of the 

 outer edge of the egg-cluster has the appearance of having been made by some external 

 container. All that can be seen, however, is the large mass of eggs adhering together 

 and apparently held in place by the twisting of the mother's body around them. I 

 cannot make a thorough examination without uncoiling the specimen and so dislodging 

 the eggs, so I have to leave a number of characters unexamined. The colour is a 

 pale brown and all the markings are faded from the body. The tentacles and cirri are 

 indistinctly moniliform.
