Habitat. — Everywhere on the shores of Britain from Shetland to the Channel 

 Islands, where it attains the maximum size, and from the tidal region to the coralline 

 ground. It lurks under stones between tide-marks, especially in pools. It is some- 

 what difficult to find, and perhaps is best obtained by placing suitable stones in vessels 

 of sea water overnight, and then examining the water-line next day. 



The variety inomata is more common on the eastern coast, whilst the variety eximia 

 is more frequent in the west and south. 



The species extends to Jan Meyen and to the shores of America (Verrill). Lenz 

 found it in the grass-wrack region of the Baltic, and Michaelsen in the tubes of 

 Sabellaria sjpinulosa at Heligoland. 



Head (Plate XXIX, fig. 8) somewhat rounded and comparatively small, having 

 anteriorly a rather short median tentacle with a few papillse on the surface. The eyes 

 are four in number ; but as the pigment of the pairs touches on each side, they are 

 connate. 1 Lateral tentacles absent. Two prominent papillse project immediately 

 behind the eyes. The palpi are somewhat massive, short, tapering organs, with a smooth 

 surface. Two short, tapering, tentacular cirri occur on each side, with small papillse 

 sparsely distributed on the surface. 



Body of forty-five to seventy segments, and about three-quarters of an inch as a 

 maximum length, small, elongated (almost linear), but slightly more diminished pos- 

 teriorly than anteriorly in young specimens. The dorsum is convex, the ventral surface 

 flattened, with a median groove in the preparations. In life the dorsum is of a pale 

 pinkish colour, slightly grained with brownish on some of the scales. A reddish mark 

 occurs in front, with a dark greyish patch a little behind. Some, as Dr. Johnston 



1 Malmgren observed that in P. minuta the eyes were four, and approximated.
