228 ANNALS OF SCOTTISH NATURAL HISTORY 



Coryphella rufibranchialis (Johnst.), sp. cap. May. 



C. lineata (Lov.), sp. cap. June. This species is usually 

 found attached to Hydroids by its tail in an erect position. 

 A case of supposed mimicry common among Eolids. 



C. Landsburgi (A. and H.), sp. cap. June. 



Lomanotus genet (Ver). This species is recorded from Lamlash 

 Bay in the "Fauna and Flora of the Clyde Area." In 1905 

 Mr. E. S. Russell took one specimen nearly 2 inches long near 

 this station. I have taken two small specimens in 18 fathoms 

 off the Farland Point, Cumbrae, which I think should be 

 assigned to this species. 



Doto pinnatifida (Mont). One specimen dredged in June 1907 

 off the station. 



Doto fragilis (Forb.) and coronata (Gmel.), sp. Among Hydroids 

 throughout the year. 



Tritonia Hombergi (Cuv.). Skelmorlie Bank (E. S. Russell). 

 Archidoris tuberculata (Cuv.), sp. Jan. to Mar. 

 Acanthodoris pilosa (Mull.), sp. Oct. ; sp. cap. Feb. 



Lamellidoris aspera (A. and H.), sp. Jan. to Mar., often on 

 Laminaria. 



Lamellidoris luteodncta (M. Sars). First taken in the Clyde in Feb. 

 1907, when several specimens occurred in each of two hauls 

 of the dredge just off Keppel Pier, Cumbrae, on hard ground 

 in 1 5 fathoms. One of these lived in the tanks until May. 

 This species is figured by Farran as Doris Beaumonti in the 

 "Irish Fisheries Ann. Rep.," 1901-2. 



Lamellidoris bilamellata (L.). During Feb. to May this species 

 occurred abundantly on the piles of Millport Pier. Its spawn 

 was also very abundant. The colour varied greatly, one 

 white specimen being found, others were nearly} white, being 

 slightly shaded with the normal brown colour. They seem to 

 feed on Alcyonidium and in turn are fed on by Portunus puber. 

 Sp. cap. Feb. and Mar. 



Goniodoris nodosa (Mont.), sp. Jan. 



Polycera quadrilineata (Mull.). This species occurs frequently 

 round the Cumbraes and is subject to considerable variation 

 in colour and the form of the external parts. Taking as the 

 normal form that figured by Alder and Hancock in their 

 monograph of the " British Nudibranchiate Mollusca," we find 

 that the greatest variation occurs in the number and size of the 

 velar processes and in the shape of the pair of dorsal papillse or 

 cerata.
