P. 86. Tigisoma lineatum (Gm.) ought to be termed T. braziliense 

 (Lin.). 



The European species of Nycticorax should be called N. griseus 

 (Lin.). The specific name gardeni was originally given to the nearly- 

 allied American species, after Dr. Garden of South Carolina. 



P. 88. Aramus scolopaceus (Gm.) was called Scolopax guarauna by 

 Linnaeus, and should therefore bear the latter specific name. 



Glottis chloropus (Nils.) should be called G. canescens (Gm.), 

 being the Scolopax canescens of the latter author. 



P. 93. The word/erws was first used as a specific name for the 

 Wild Goose by Stephens, not by Gmelin, and is therefore subsequent 

 to Meyer's name cinereus. 



The Wild Swan should be termed Olor musicus (Bechst.), as Lin- 

 naeus did not distinguish it specifically by the name oiferus. It may 

 be further remarked, that the characters which distinguish Olor of 

 Wagler from Cygnus are far too unimportant for generic separation. 



P. 94. Pcecilonitta should be written Pcecilonetta. 



The original type of the genus Querquedula (Briss.), Steph., is 

 clearly the Garganey (Anas querquedula, Lin., Cyanopterus circia 

 (Lin.), Eyton), and not the Teal (Anas crecca, Lin.). But would it 

 not be better to follow Stephens in uniting the Teals and Garganeys 

 in one genus, Querquedula ? 



P. 96. The specific name leucocephala, Scop., is prior to mersa, 

 Pall. 



Mergus castor, Lin., should be called M. merganser, Lin., as the 

 former synonym applied to the female, while the latter name was 

 given to the adult male. 



P. 98. Those who adopt Mcehring's genus Uria should retain for 

 its type the specific name grylle, Lin. But as I consider that Mceh- 

 ring's work is beyond the pale of the binomial nomenclature, I adopt 

 Stephens's name of Grylle scapularis. 



Buffon's PI. Enl. 993 represents the Thalassidroma oceanica 

 (Forst.), not T. pelagica (Lin.). 



P. 100. Gygis Candida (Forst.) was first published by Sparrman 

 under the name of Sterna alba, and the latter specific name ought 

 therefore to prevail. 



P. 101. The name Onocrotalus, Briss., should be cancelled as a 

 mere synonym of Pelecanus, Lin., and a new generic name should 

 be given to the Pelecanus thagus of Molina.

DR. MARTIN BARRY ON FIBRE. 



Dr. Barry requests us to add the following, in connexion with his 

 Memoir on Fibre, an abstract of which is given at p. 502. 



The " white substance of the nervous fibre," surrounding Remak's 

 4( band-like axis," consists of filaments having the remarkable struc- 

 ture above described, and often curiously interlaced with one an- 

 other, as though each of them had a spiral direction. In examining
