170 Miscellaneous. 



Therein I never used the word " subspecies," and I expressly 

 stated that I counted Lagopvs scoticus " as a species," though 

 I was persuaded (as I still am) that " it is only L. albus modi- 

 fied to suit an insular climate "*. Furthermore, L. mutus, 

 L. rupestris, and L. hemUeucurus were not considered by me 

 to have any such very near relationship to L. albus as I con- 

 ceive L. scoticus to have. 



Page 239, line 24. The " certain uniformity of tints " spoken of 

 exists, except in the female, at one time of the year only, and 

 even then is not applicable to L. scoticus. 



Page 240, footnote. For " seems to entertain " read " entertains." 



Page 241 , lines 7, 8. The Black Grouse is far less " common in the 

 mountains of Sweden and Norway " than it is in the lower 

 districts. 



Page 244, line 5. The statement that the "Wild Swan " inhabits the 

 Polar regions " gives a very incorrect impression ; for most of 

 the AVild Swans that visit "Western Europe are bred in Iceland, 

 altogether outside the Arctic Circle, while the species found in 

 the Polar regions of America are most likely quite distinct from 

 those which inhabit the Old "World. 



In noticing these errors I have omitted any reference to some 

 others which have been already corrected in the concluding portion 

 of the ' Peliquite Aquitanicae ' (p. 292); and I may perhaps be 

 allowed to add that my sole object has been to contribute to the 

 utility of that work. I certainly impute no blame to its learned 

 Editor or to my distinguished friend M. Alphonse Milue-Edwai*ds. 



On the Verminous Pneumonia of Domestic Animals. 

 By M. E. Bttgnion, 



M. E. Bugnion communicated to the meeting of the Swiss Society 

 of Natural Sciences, held at Andermatt in September last, some 

 observations on the pneumonia produced in domestic animals by the 

 presence of parasitic worms in the lungs, which seem to be of much 

 practical interest. He insisted especially upon the different forms 

 assumed by the disease according as it is caused by adult Strongyli 

 or by ova and embryos. Up to this time he has observed : — 



1 . A lobular form, produced by adult Strongyli coiled up in the 

 bronchi. 



2. A diffused form, caused by ova and young larvae of Nematodes 

 scattered by thousands in the tissue of the lungs. 



3. A nodular or pseudo-tubercular form, produced by the accumu- 

 lation of the ova at certain limited points of the lung. 



The first form was studied in the calves and heifers of the Jura, 

 where this disease sometimes acquires an epizootic character. During 

 the great slaughter ordered by the Government of the Canton de 

 "Vaud on the pastures of Neuvaz (Jura) in September 1874, on
