Eteone depressa Malmgren.

p. 119. 



A single specimen, found in sand in Blacksod Bay, agrees almost exactly 

 with the species recently described by Mcintosh as Eteone depressa Malmgren. 

 It is much smaller, however, being only 20 mm. long, with 130 segments, 

 whereas Mcintosh's specimen was 80 mm. long. Such slight differences as 

 occur are probably due to difference in age and size. The colouring agrees 

 exactly with Mcintosh's description. The head is more sharply marked off 

 from the buccal segment. The dorsal tentacular cirri are shorter than the 

 ventral pair. This species agrees with E. arctica in having a well-developed 

 setigerous lobe and setae on the second segment, in the shape of the short 

 spatulate anal cirri, and the form of the setae. The structure of the foot is 

 somewhat different, the dorsal cirrus being broader and more pointed at the 

 tip. These differences are very slight, and I am doubtful whether this form 

 deserves specific rank. The use of this specific title by Malmgren, Theel, 

 Mcintosh, Fauvel, and others seems very arbitrary. 



A specimen agreeing with the above description was found in sand in 

 Dublin Bay.

Family TOMOPTERIDAE. 

 Tomopteris helgolandica Greeff.

A full account is given in the above paper of the distribution of this 

 species in Irish waters. It was not found in Blacksod Bay. In Clew Bay 

 it was found on 4 occasions. Within a radius of 15 miles of Inishbofin, 

 including Ballynakill Harbour, it was found on 53 occasions. 



This species is widely spread in the Atlantic and Mediterranean, and 

 probably occurs in the Pacific. 



Family NEREIDAE. 



Two species of this family known to occur in Irish waters were not found 

 in the Clare Island area, viz., N, sonata Malmgren, a northern species found
