the name cannot stand for a genus of the Phyllodocidae, and I suggest 

 Paranaitis instead. 



Paranaitis Wahlbergi (Malmgren). 

 PI. VIII, fig. 16.

A single specimen of this species was dredged in 18| fins., in Clew Bay. 

 The living animal was pale yellow in colour, with bright red bands across 

 the back and on the cirri, especially marked in the region of the 6th-8th 

 segments. Thus the colour pattern is very similar to that found in Paranoids 

 rosea and P. Jeffreysii. The preserved animals lose the red pigment, and are 

 pale yellow in colour. 



As no accurate figures of the setae of this species have yet been published, 

 I have drawn carefully the end of the shaft of the seta (fig. 16) to show its 

 peculiar character. The tip is bevelled, and the main fang is deeply bifid. 

 Sometimes the teeth are equal in size, sometimes one is slightly longer than 

 the other. Below the main tooth, the tip of the shaft has a number of 

 conspicuous spines. 



The anal cirri are small and globose, as Malmgren figures them. The 

 tentacular cirri have filiform tips. The first segment is prominent, and 

 projects slightly over the head. The latter has two large eyes, with lenses. 



Habitat. — Clew Bay — Dredged in 1S| fms. 



Distribution. — Donegal Bay ; Sweden ; Iceland ; Spitzbergen ; Nova 

 Zenibla ; Kara Sea ; Skagerrak ; Kattegat. 



Paranaitis Jeffreysii (Mcintosh). 



1908. Anaitis Jeffreysii. Mcintosh, p. 73. 



This species has previously been found only in Valencia Harbour, and 

 was apparently described from a single preserved specimen. I have examined 

 a number of living specimens, and am able to supplement the description 

 given by Mcintosh. 



The head is white, and the back is coloured with alternating bands of 

 white and greenish-brown. The first and second setigerous segments are 

 almost covered with broad dark bands of the same greenish-brown colour, 

 which is also present on the dorsal cirri. Thus all three Irish species of this 

 genus agree in having pigment specially concentrated on some of the anterior 

 segments. 



In preserved specimens the greenish-brown pigment is still visible,
