3. P. canis, Duges. This has shorter legs than Irritans, the tibiae 

 are thicker, and the femora ahnost bare. Curtis has figured dissec- 

 tions in his " British Entomology." 



4. P. felis, Bouche. Common on cats. 



5. P. erinacei, Bouce. Common on hedgehogs. 



6. P. sciuromm, Bouche. Common on squirrels. 



7. P. niartis, Bouche. Common on weasels, ferrets, and stoats. 



8. P. goniocephahis, Tasch. On rabbits, especially about the ears. 

 This is probably the same species as that found on the hare, which 

 Leach called Leporis. 



g. P. gliris, N.S. On dormice. This is very different from that 

 found on ordinary mice, and more nearly resembles Mavtis and Felis. 

 Perhaps, after all, these four last, and Felis as well, are but one species. 



10. P. gallincB, Bouche. Common on hens, especially in their 

 nests. I have also found it on sparrows, starlings, jackdaws, black- 

 birds, thrushes, robins, creepers, wrens, long-tailed tits, jays, yellow- 

 hammers, and rnoor-hens. It also attacks the domestic fowl in Ceylon, 

 attaching itself by its rostrum in considerable numjbers around the 

 eyes and on the neck of the bird. It can easily be distinguished from 

 all other British fleas by the length of the antennae, and also by being 

 of a much blacker colour. P. fringilla, Walk., and Sanopsylhis galli- 

 naceous, Westwood, are probably synonyms of this species. 



11. P. hirundin is, Curt. On swallows and martins. This differs 

 from GallincB in being testaceous instead of piceus fuscus, in being rather 

 more elongated, and in having shorter antennae. Curtis has figured 

 the head, tarsi, antennae, and other dissected parts, in his " British 

 Entomology." 



12. P. columbcB,V\[diV^. On wood-pigeons and other pigeons. This 

 likewise differs from Gallijue in being testaceous ; but it is far less 

 elongated than either it or Hirimdinis. 



13. Ceratophyllus elongatus, Curt. Infests the Noctule bat. It 

 was beautifully figured and described by Curtis in his " British Ento- 

 mology," but re-described and named Typhlopsylla octactemis by 

 Kolenati. 



14. C. vespertilionis, Duges. Common on the long-eared bat. 

 Re-named Typhlopsylla hexactenus by Kolenati many years after. 



15. C. musculi, Duges. Common on mice.
