NOTES ON THE LITTORAL POLYGH^ETA OF TORQUAY. 199 



Odontosyllis gibba, Clpd. Mcintosh, Mon. Brit. Annel., vol. ii. 

 p. 183. 



Several examples of this species were obtained from Corbyn's Head. 

 They agreed in colour with the one from Plymouth figured in Mon. 

 Brit. Annd. In one example two red eye-spots in front of the anterior 

 pair of large eyes were distinctly observed. These additional spots 

 apparently have only been previously observed in the Unihellisi/llis 

 fasciata of M. Sars which, according to Mcintosh, is the same species. 



Odontosyllis ctenostomata, Clpd. Mcintosh, Mon. Brit. Annel, 

 vol. ii., p. 182. 



The most abundant of all the species of Syllids at Torquay. 



The colour is usually yellowish green. In glass vessels it creeps to 

 the edge of the water. Although unripe individuals are so numerous, 

 only one or two, females, were found with swimming bristles. 



Amblyosyllis lineata, Grube. Mcintosh, Mon. Brit. Ann., vol. ii., 

 p. 225. 



Occasionally met with in weeds from the rocks between Oddicombe 

 and Babbicombe beaches. One individual was marked with purple 

 stripes, and appeared to belong to the variety /or??io,9a. 



Syllis spongicola, Grube = >S'. hamata, Clpd. Mcintosh, Mon. Brit. 

 Annel., vol. ii., p. 197. 



Fairly abundant. The colour is rather a reddish brown than orange. 

 Several females with ova showed no signs of swimming bristles or 

 formation of a bud. - Only one individual showed a distinct bud with 

 ocular spots on each segment. 



Syllis prolifera, Krohn. Mcintosh, Mon. Brit. Annel., p. 161 (as 

 Pionosyllis prolifera). 



One of the most numerous of the Torquay Syllids, It appears to be 

 a very variable species, both as regards the number of the articulations 

 of the cirri and the colouring. Some have markings like those given in 

 Mon. Brit. Annel., fig. 53, others like the variety variegata as figured 

 by Marenzeller, while some are uniformly coloured. 



The articulations of the longer dorsal cirri, in some cases, are as many 

 as fifty. Several with buds were found ; one with a regenerated head, 

 without proboscis or proventriculus, exactly like that described by 

 de St. Joseph. Ann. Sc. Nat., 1886, p. 147. 



Syllis alternosetosa, de St. Joseph. Ann. Sc. Nat., 1886, p. 150. 



The species found at Torquay is undoubtedly the one so fully 

 described by de St. Joseph. Malaquin, in his Recherches sur les Syllidiens, 

 considers S. alternosetosa as identical with S. hyalina, Grube. But this 

 species, as described by Mcintosh, Mon. Brit. Annel., vol. ii., p. 167,
