Syllis (Typosyllis) prolifera Krohn. 



1908. Pionosyllis prolifera. Mcintosh, p. 161. 



This species is very abundant throughout the district. Stolons with male 

 buds attached were found in Clew Bay in May, and Chaetosyllis buds were 

 taken at the surface on several occasions in June and August at Ballynakill 

 and Bofin. 



Habitat. — Blacksod Bay — Common on shore, and in Laminaria roots. 

 Taken on ten occasions. Dredged on five occasions, in 

 1-8 fms. Clew Bay— Shore of Clare Isd., at Portarriff. 

 Dredged on eight occasions, in 4-17 fms. Ballynakill 

 Hakbouk — Taken on five occasions, in 0-8 fms. Bofin 

 Harbour — Taken in surface tow-net. 

 Distribution. — Great Britain ; Spitzbergen ; Madeira ; France ; Mediter- 

 ranean ; South Africa. 



Syllis (Typosyllis) Krohnii Ehlers. 

 1908. S.K. Mcintosh, p. 192. 



This is one of the rarest of the Syllidae in our district, only 3 specimens 

 having been obtained. 



Habitat. — Blacksod Bay— One specimen in weeds from shore of Carrigeen- 

 more. Clew Bay — Dredged in 7 fms. Ballynakill 

 Harbour — Dredged in 1-3 fms. 

 Distribution. — Great Britain ; France ; Madeira ; Canaries ; Mediter- 

 ranean. 



Syllis (Typosyllis) vittata Grube. 



1864. Syllis aurita. Claparede, p. 539. 1874. Syllis vittata. Maren- 



zeller, p. 35. 1875. Syllis aurita. Marion and Bobretzky, p. 17. 



1908. Syllis Buskii. Mcintosh, p. 206. 



A large number of specimens of this species were dredged a one station 

 in Clew Bay. The characteristic purple or brown transverse bands on the 

 dorsum are only faintly indicated in the preserved specimens. In the struc- 

 ture of the elongate palps, cirri, setae, etc., they agree closely with the 

 descriptions of S. vittata and S. aurita, which are now regarded as the same 

 species. There is nothing to distinguish Syllis Buskii of Mcintosh from this 

 species, though no information is given as to the colour. The oesophagus 

 and proventriculus are very long, the former extending to the 13th segment, 

 the latter to the 19th, agreeing with Marenzeller's description. The 

 proventriculus had 45 rows of glands. In small specimens the bifid nature 

 of the setae can be plainly seen, especially in the posterior segments ; but
