Of these species only T. helgolandica occurs in the coastal 

 waters and inland seas. The others are found in the 

 European branch of the Gulf Stream, which flows in a 

 northerly direction past the west coast of Ireland. 



A full report on this collection will shortly be published in 

 the ' Scientific Investigations ' of the Fisheries Branch. 



The two new species of Travisiopsis are distinguished by 

 the following characters: — 



Travisiopsis lanceolata, sp. n. 



Length 25-30 mm. Number of body-segments 22. Me- 

 dian dorsal papilla pear-shaped, with free posterior lobe. 

 Lateral tentaclrs long, reaching as far back as the middle of 

 the fourth segment. Prostomium conical, with filiform tip. 

 Cirri almost square, with narrow area of attachment. Anal 

 cirri powerful, lanceolate. Longitudinal muscles in dorsal 

 and ventral pairs, broad and close together. 



y Travisiopsis levinseni, sp. n. 



Length 20-24 mm. Body much slenderer than in the 

 previous species. Number of body-segments 25. Median 

 dorsal papilla sessile, without the posterior projecting lobe. 

 Lateral tentacles short and thick. In front of these, on each 

 side, is a smaller lobe. Prostomium conical, with filiform 

 tip. Cirri square, with very broad area of attachment. 

 Anal cirri powerful, spatulate. Longitudinal muscles in 

 dorsal and ventral pairs, narrower and further apart than in 

 T. lanceolata.
