g. Species to Look For. 

 It will be observed from the above list that we now record 

 32 out of the 45 known British species. More attentioii and 

 research — especially amongst sea-birds, small rodents and bats 

 — will still further increase our list and probably add to our 

 knowledge of the Order. It is therefore advisable briefly to 

 review the 13 species we have not yet succeeded in securing 

 locally : — 



BIRD-FLEAS, 3 SpCcleS. 



OrnithopsyUa laetitice Roths. (1908). 



" Only recorded from the Scilly Islands, where it frequents 

 the nests of sea-birds. The real host is probably the Manx 

 shearwater {Puffinus augloruni). Not yet observed on the 

 Continent." 



Ceratophyllus rothschildi^dX^xsX. (19 10). 



" A very rare species apparently confined to Great Britain. 

 A few examples were found by the Rev. James Waterston in 

 the nests of the house martin {Chelidon urbica), in Kin- 

 cardineshire." 



Ceratophyllus borealis Roths. (1907). 



" A rare species, apparently confined to Great Britain, ami 

 so far only recorded from Scotland from the nests of the rock 

 pipit {Anthus obscuri/s), the gannet {Si/la bassaiia), and some 

 other birds."
