Habitat. — This species is conspicuous because of its clear, rosy 



or flesh-like color, which is all the 

 more striking in contrast with the 

 black mud in which it is usually 

 found. It occurs between tides in 

 muddy locations over a large ])ortion 

 of the southern Alaska coast. It 

 was collected at Taku Harbor, Sitka, 

 Yakutat, Prince William Sound, and 

 Popof Island on the Harriman Ex- 

 ])edition, although only a few s])eci- 

 mens were found at each locality. 



A large individual collected by 

 IMr. Shearer at Albert's Head, Van- 

 couver Island, had 13 proboscidial 

 nerves, and the proboscis was pro- 



Vic.iO.-Paranemertescarnea. Ex- vided with six poucheS of accessory 



tremity of everted proboscis, with stylets, containing four moderately 



six pouches of accessory stylets, of ^' -i , ^ . \ 



which four are shown. " slender stylets each.

 Diego, California. The more striking peculiarities of external 

 appearance and internal anatomy are given in the following para- 

 graphs : 



Body long, moderately slender, rounded or cylindrical in the short 

 esophageal region, very much flattened farther back ; head small 

 and acutely pointed in ordinary states of contraction ; with two 

 pairs of oblique grooves uniting in mid-dorsal line ; snout with the 

 ocelli can be retracted to a very considerable extent into the tissues 

 of the head. Intestinal region flat and ril)bon-like with thin mar- 

 gins which are sometimes bent toward the ventral surface, often 

 much wrinkled when the body is strongly contracted ; posterior 

 extremity rounded.
