448 PARASITES OF ANIMALS 



and L. tridactylus) the Tetrabothrium cylindraceum. Also 

 from the grey gull Echinostoma spinulosum. From the red- 

 throated diver I procured Tetr. macrocephalum. I found this 

 tapeworm also in the guillemot (Uria troile), together with a 

 nematode (Ascaris spiculigera) two examples of which were 

 lodged in the right auricle of the heart. From a capercaillio 

 (Tetrao urogallus) I have obtained a species of Ligula, and 

 likewise numerous examples of Trichosoma longicolle. Of 

 necessity, this brief notice only comprises a small part of the 

 avian entozoa contained in my collection, many of which I have 

 not had time to describe, whilst, as regards others, I can only 

 say that they remain in abeyance for examination and identifi- 

 cation. 



Mr Brotherston has recently recorded an interesting find 

 (made Nov. 25th, 1874) of nematodes in the legs of the lesser 

 grebe (Podiceps minor), and also (Feb. 27th, 1878) in the water- 

 hen (Qallinula Moropus). Both limbs of both birds were in- 

 fested. The worms of the grebe were spirally coiled amongst 

 the muscles and tendons near the lower end of the tibia, and 

 when unrolled measured about an inch in length. The para- 

 sites of the waterhen were similar in appearance. Not impro- 

 bably these were all sexually-imperfect female examples of 

 Filaria acuta hitherto found in the abdomen of grebes. 



The British Museum contains many interesting specimens 

 purchased from the collection of Von Siebold, but they are 

 practically inaccessible to investigators. The entozoa in the 

 Hunterian Collection, though few in number, are in an excellent 

 state of preservation, and at all times accessible to visitors. 



The ectozoa of birds are too numerous to be dealt with in 

 these pages. References to recent papers by Haller, Megnin, 

 and Westwood will be found below. The insects infesting the 

 domestic fowl have been alluded to in connection with the 

 occurrence of poultry-lousiness in the horse.
