Many knotty problems presented themselves for solution. 



I. Area. — This question was thoroughly discussed, and the 

 final decision was to accept Canon Norman's definition of the 

 British Area, as laid down in his paper in the Annals and 

 Magazine of Natural History (6), V^ol. V., pp. 345, 454. (1890), 

 but with the addition of the Channel Isles. The area embraces 

 the Dogger Bank, but excludes the "Cold Area" between the 

 Shetlands and the Faroes. The area being defined, the com- 

 mittee were at liberty to include in their list all the mollusca 

 obtained by different expeditions within the British limit, and of 

 these the following are the more important : — 



(1) The "Lightning,"' in 1868, under Drs. Carpenter and 



Wy ville Thomson ; 



(2) The "Porcupine," in 1869, under the same scientists, 



with the addition of Dr. Gwyn Jeffreys. Only the 

 mollusca obtained by these expeditions within the 

 defined British area could be used in the compilation of 

 the list (Proc. Zool. Soc, 1878-85); 



(3) The "Knight-Errant," in 1880, under Sir John Murray 



(Proc. Royal Soc. Edin., Yol. xi.) ; 



(4) The "Triton," in 1882, under Sir John Murray (Proc. 



Zool. Soc, 1883); 



(5) The Royal Irish Academy's Expedition in the " Lord 



Bandon," in 1885-86 ; and in 



(6) The "Flying Falcon," in 1888 (Proc. R.I.A., 1886, 1898), 



(7) The "Flying Fox," in 1889, under the Rev. W. Spots- 



wood Green (Ann. and Mag. JVat. Hist., Ser. 6, Yol. 

 IV., 1889, p. 409). 

 (S) H.M.S. "Research," in 1889, by Mr. G. C. Bourne 

 (Journal of the Marine Biological Assoc, of the United 

 Kingdom, N.S., Vol. I., 1889-90, p. 306). 



II. Classification. — The Committee found that while Jeffreys' 

 classification was admittedly very defective, there was no other 

 scheme in the field at present which it would be advisable to
