NOTES ON THE LITTORAL POLYCH.^TA OF TORQUAY. 351 



fusiform and are tinged with yellow. The body is coloured purple. 

 The jaws are about twice as long as broad, the number of teeth in each 

 jaw five. There are no denticles. The first pair of feet, which are 

 uniramous, are attached to the buccal segment. The second pair are 

 also uniramous, but all the other feet are deeply bifid. 



There are about twenty bristles in each foot, the terminal pieces of 

 which are straight and narrow ; they are much longer in proportion to 

 their length than those shown in Claparede's drawing. Bristles and 

 spines are colourless. The drawing given by Claparede is quite 

 accurate for an individual drawn under compression, but the feet and 

 cirri as shown there are much flattened out. 



Leptonereis Vaillanti. de St. Joseph, Ann. des Sc. Nat. Zool., 

 vol. v., 1888, p. 246. 



One imperfect male Heteronereid form of this species was found in 

 the month of February at Oddicombe. The posterior of the three 

 regions into which the body is divided was absent, but the remaining 

 segments agreed with the description and figures given by de St. Joseph. 

 It is not recorded in the " Fauna of Plymouth." 



Nereilepas fucata, Savigny. Mcintosh, Mon. Brit. Ann., vol. ii., 

 PL LXi, Figs. 6 and 6a. 



This is not strictly a littoral species, but may be sometimes found in 

 whelk shells thrown up on the shore. One lived for about six months 

 in a small aquarium in a broken whelk shell, but without any hermit 

 crab. It usually had the head and about ten or twelve segments of 

 the body protruding from the shell ; this part of the body being curved 

 and continually waved backwards and forwards, giving the worm a 

 most curious resemblance to a cobra. 



Nereis pelagica, L. Mcintosh, Mon. Brit. Ann., vol. ii., PI. lx, 

 Figs. 6 and 6a. 



This Nereis is extremely common in the roots of the Laminaria, 

 nearly every root containing one or two. Several of the Heteronereid 

 form were found in the same situation in January and February, 1907, 

 on Oddicombe beach. They measured about 30 mm. in length. 



Nereis Dumerilii, Aud. and Ed. Mcintosh, Mon. Brit. Ann., vol. ii., 

 PI. lx, Figs. 10 to 10c. 



Small individuals, 20 to 30 mm. in length, are very common amongst 

 lagse from rock pools and the Torquay harbour.
