348 NOTES ON THE LITTORAL POLYCH.ETA OF TORQUAY. 



The number of segments per inch of length mentioned by Johnstone 

 applies much better to ornata than to E. ncbulosa, Montagu. 



The variety aurea of Gravier is also found at Torquay in the same 

 localities as ornata. The dorsal cirri are distinctly less pointed, and 

 the breadth of the segments greater in proportion to the length than 

 in the case of the other varieties.

One specimen only from Corbyn's Head. Colour dull green rather 

 than yellowish or red ; some of the dorsal cirri heavily marked with 

 dark colouring matter. The much longer upper limb of the bifid 

 setigerous process of the foot is very characteristic of this species.

The real distinction between the genera Eulalia and Eumida, as 

 defined by Malmgren and Mcintosh, is that in Eulalia the first pair of 

 tentacular cirri are attached to a segment divided from the head by 

 a constriction visible at least on the ventral side, while in Eumida. the 

 first pair of tentacular cirri are apparently attached to the head, the 

 first segment being soldered to the head. Such a distinction is, how- 

 ever, unsatisfactory, because the visibility of a dividing line between 

 the segment and head depends so much on the method of preparation 

 of the specimen. The only British species is, however, easily recognised 

 as a rule by the peculiar white markings, which look as if they had 

 been painted on with Chinese white. It is common amongst the 

 Laminaria roots at Torquay. Most of the specimens are coloured 

 ajpale brown, but one or two were found with a decided red tinge in 

 the^posterior part of the body. 



The proboscis is covered with very small papillae, which almost or 

 entirely disappear in preparations, for which reason the smoothness of 

 the proboscis as a generic distinction is also objectionable. Some 

 of the individuals had black patches in the intestines like those 

 described by Gravier in his Eumida communis. Bull. Sc. Fr. Belg., 

 t. xxxix., p. 18. 



Phyllodoce maculata, Johnstone. Mcintosh, Mon. Brit. Ann., 

 vol. ii., p. 89. 



This is the only species of Phyllodoce which is at all common between 

 tide marks at Torquay. It is found amongst rucks and weeds, and 

 also in the sand. On one occasion sixteen individuals were found
