Galls of Norway. By Prof. J. W. H. Trail, A.M., M.D., RL.S. 



(Read 13th June 1889.) 



While my paper upon the " Galls of Norway " was in the 

 press last year, a valuable contribution to the same subject, by 

 Dr Franz Loew, was read before the Viennese " Zoologisch- 

 botanisch Gesellschaft " on 2nd May 1888, and was published 

 in the Verhandlungcn in the course of the summer (vol. 

 xxxviii. pp. 537—48). It bears the title Norwcgische Phytojjto- 

 und Entomo-cccidien (Norwegian Mite- and Insect-Galls), and 

 is based upon materials collected in middle and northern 

 Norway, from 8th July to 3rd August 1886, by Dr Joh. 

 Liitkemiiller. 



With the view of completing the record in this Society's 

 Transactions of what has been published upon the " Galls of 

 Norway," it seems desirable to add a summary of this valu- 

 able paper to what has been published by myself last year. 

 The latter included everything that was known to myself 

 upon the subject up to the date at which my paper was 

 written ; and Herr Sch0yen has recently informed me that, 

 so far as he knows, it was virtually complete up to date, as 

 Herr Brunchorst's work (to which reference was made in a 

 note added to my paper just l;)efore publication) contains 

 nothing additional upon the Norwegian galls. 



Dr Loew's paper adds largely to mine as regards the 

 localities (the Hardanger Fiord and Troudhjem being the only 

 localities common to both), and also in the kinds of galls 

 found, Dr Liitkemiiller having fallen in with a number that 

 were not observed by me, while not a few of mine had 

 escaped his notice, — the result, perhaps, of botanising in 

 different parts of Norway. 



The localities referred to in Dr Loew's paper are as follows, 

 the figures after each denoting latitude N. :— 



Ulvik, on the Hardangerfjord (60° 35'); Stalheim (60° 

 51'); Falejde, on the Nordfj'ord (60° 54'); Merok, on the 

 Geirangerfjord (02° 7'); Moldo, on the Moldefjord (62° 44'); 

 Trondhjem, on Trondhjem Fjord (03° 25'); Svartisen, on 

 Holandfjord (06° 45'); Bodi> (67° 17'); Lyngseidet, on Lyn- 

 genfjord (60° 34'); Tromso (60° 38'); Hammcrfest (70° 37'); 

 North Cape (71° 7').
