ANNELIDS. I. 61 



"The lamellae (dorsal cirri) are of a rich deep green or blackish-green with a border of yellow or 

 greenish yellow, and they have a tendency to be curled and twisted, especially in specimens in con- 

 finement, a feature greatly increasing the complexity of the dorsum." Unfortunately I can say nothing 

 about the colour in the specimen from the Faroe Islands after its preservation for many years in 

 alcohol; the present colour is quite uniform dark brownish with a reddish hue; but the large, dorsal 

 lamellae are highly "curled and twisted" as is plainly shown in my figure of the parapodium (PI. V, fig. 3). 



I have figured a bristle (PI. IV, fig. 7). The fig. 1 c of Claparede appears rather a failure, though 

 it shows the same swelling of the distal part of the shaft as seen in my figure, and what the same 

 author gives in the text can be referred to several species of Phyllodoce. 



Hitherto the species under consideration is known from the Mediterranean and from the coasts 

 of England and France. Likely the locality in the Faroe Islands will prove to be the northernmost.

Locality: 



Off Jan Mayen. 55 fins. 



55°4i' N. L I4°09' W. L. 63 m. West coast of Iceland. 



Bakkefjord, 28 fans. Iceland. 



One specimen is present from each of the above named localities. 



The species has a rather wide geographical range, but it does not appear to be common any- 

 where. It is known from Iceland, Spitsbergen, Novaya Zemlya, the Kara sea, the sea north of America, 

 Norway, the North Sea and the Cattegat.

 Locality : 



The Ingolf-Expedition St. 25. 63°3o' N. L. 54°25' W. L. 582 fans. The southern part of Davis Strait. 



Only one specimen has been taken; it is in a rather bad condition. 



The length is 20 mm.; the greatest breadth, setae counted, is 2 mm. 



Habitually the animal calls to mind Anaitis Wahlbergi; the body is somewhat flattened and 



the dorsal lamellae are densely pressed to the dorsum, leaving the midmost part of the latter uncovered. 



1 In his paper "Zur Systematic der Polvchaetenfamilie der Phyllodocidna" Erik Bergstrom maintains that Anaitis 

 kosteriensis is a well-marked species.
