456 Rev. Canon Norman's Revision 



The following dredgings of the British Government expe- 

 ditions were beyond the British area: — 



1. 'Lightning,' 1868.— Stats. 2 to 11, 15, 16, which were 

 all too far north. The only stations therefore of this expe- 

 dition which were within our area were 1, 12, 13, 14, 17. 



2. 'Porcupine? 1869.— St. 11, in too deep water, 1630 

 fathoms ; Stats. 33 to 42 too far south ; Stats. 51, 52, 53, 54 to 

 64, 76, 77, 83, too far north. Three other dredgings should 

 in my opinion, and in accordance with the views expressed in 

 last month's * Annals,' be excluded. Stat. 54, lat. 59° 46' 

 N., long. 6° 27' W., 490 fath., temp. 31°'4 Fahr., and Stat. 

 86, lat. 59° 48' N., long. 6° 31' W., 445 fath., temp. 30°'l 

 Fahr., are slightly to the south of the northern boundary, 

 but at that particular spot the Faroe Deep crosses lat. 60 , 

 and the Faroe Ridge is to the south of it ; consequently it is 

 thus part of the " cold area " with the water below freezing- 

 point *, and this little southern projection of the cold area 

 should be rejected. Again, Stat. 65, lat. 61° 10' N., long. 2° 

 21' W., 345 fath., temp. 30° Fahr., is exactly on the boundary 

 line which runs north-east, and the temperature being below 

 freezing-point, this dredging I also exclude. 



* Porcupine] 1870. — No dredgings of this year were within 

 our area. 



3. 'Knight Errant, 1880.— Stats. 1, 2, 8 were too far 

 north. 



4. 'Triton? 1882. — Stats. 3 to 9 and 12 were too far north. 

 The only dredgings in this expedition south of lat. 60° N. 

 were 1, 2, 10, 11, and 13. 



Great caution must be used in reading Jeffrey s's notes of 

 species in his scattered records. He often uses such loose 

 expressions as " north of the Butt of Lewis " or " to the north 

 of Scotland," when the shell was really found north of lat. 

 60° N. and in the " cold area " of the Faroe Channel. 



The following is a list of papers by Dr. Jeffreys in which 

 allusion is more or less made to Mollusca procured in the 

 ' Porcupine ' and other expeditions : —

 Report of the Scientific Exploration of the Deep Sea in

1870. Carpenter and Jeffreys. " Report Deep-Sea Researches,
