MALLOPHAGA. 



Only one species of bird-louse was obtained by the Percy Sladen Trust Expedition. 

 Through the kindness of Professor G. H. F. NuttaU it was submitted to Professor L. G. 

 Neumann of Toulouse, to whom its determination is due. 



LiPEURUS, Nitzsch.

Loc. Aldabra : a number of specimens were collected by Fryer from the flamingo 

 Phcenicopterus minor, 1908—9. Professor Neumann stated (in. litt.) that this species

 the hut at Mare aux Cochons : there were no other human habitations near, but the 

 thick palm-leaf thatch of the hut was tenanted by many rats. A single specimen was 

 also collected in Mahe (Cascade Estate, II. 1909). 



DIPTERA PUPIPARA. 

 Hippoboscidse. 



Only two species of this family are represented in the collections formed by the 

 members of the Expedition. Both are found all over the warmer parts of the globe. I am
