In the ? the eighth abdominal tergite hears laterally towards the base only 

 one bristle, and the seventh sternite has five bristles on the two sides together. 



The specimens which we have from Sardinia, Corfu, and Asia Minor do not 

 belong to this race, but appear to ns to agree perfectly with Central European 

 erinacei. 



3. Ceratophyllus laverani Roths. (1011). 



A very large series of both sexes was obtained from an old bird's-nest found 



near Cintra on April 25th, 1010. The nest was built about a yard and a half 



above the ground in a small tree. It rested on the toii of the cut-off stem, and 

 was protected by some branches. The nest had a very dilapidated look, and 

 appeared to be a last year's nest of a Blackbird. We expected to find some 

 Staphylinid beetles in it, and therefore put it into a bag to take it to the hotel 

 for closer examination. But when I withdrew my hand from the bag I was not 

 a little surprised to see a number of pale fleas crawling about my fingers. The 

 nest was literally swarming with them. — K. J. 



The species was still uudescribed at the time, but we have since received it from 

 various places in the Alps, France, and Sardinia. The trne host is Mi/oxng glig. 

 It is therefore probable that a Mi/oxiis bad chosen that bird's-nest as a sleej)ing- 

 place, and infested it with C. laverani. We have also found the same species 

 of flea in a bird's-nest in the French Alps. 



4, Ceratophyllus gallinulae Dale (187s). 



8 (?£?, 27 ? ?, and some larvae; Monchiqne, Algarve, May 10, lOli), from 

 the nest of Tardus mertda. 



The nest was bronght to us by a boy. We did not observe any fleas in it, 

 but saw some flea-larvae underneath the wings of a dead young bird which was 

 in the nest, and had apparently been dead only a few hours. Under a lens the 

 larvae were seen making movements as if they were feeding on the epidermis 

 of the bird. The above series of specimens was subsequently bred from the 

 nest. The larvae had a blackish grey appearance, with pale intersegmental rings. 

 When bronght to the window for observation and exposed to the bright daylight, 

 they at once ceased feeding and hastily left the bird, falling back into the nest. 



5. Ceratophyllus londiniensis Roths. (1903). 



5 ? ?, Cintra, April and 11, 1911, o& Mus muscnlus. 



2 ? ?, Monchi(|ue, Algarve, May 13, 1900, off the same host.

 sylvaticus. 



The mice were all trapped in the garden below Lawrence's Hotel at Cintra. 



7. Palaeopsylla atlantica spec. nov. 



9 6S and 9 ? ?, Monchique, Algarve, May II, 12 and 13, 1910, off Talpa 

 europaea. 



Our knowledge of Palaeopsylla dates from the publication of A. Dampfs 

 researches on this genus.
