Apodiformes 

 Genera of Mallophaga recorded in Britain : Dennyus, Eureum 



( Amblycera) . 



The swifts are the only order of birds known from which no member 

 of the superfamily Ischnocera has been recorded. They harbour species 

 of two related genera of Amblycera, which are unlike those found on 

 any other order of birds and confirm the isolated position of the swifts 

 within the class Aves. 



Caprimulgiformes 

 Genus of Mallophaga recorded in Britain : Mulcticola (Ischnocera). 



The British nightjar has only one species of Mallophaga, a wing 

 louse. Other kinds of nightjars found in the New World are, however, 

 also parasitised by a head louse. 



Coraciiformes 

 Genera recorded from the order in Britain : Alcedoecus, Alcedqff'uia 

 (Ischnocera) from kingfishers; Meropoecus^ Briielia (Ischnocera) from 

 the bee-eater; Menacanthus{Amb\ycQY2i), Upupicola {Ischnocera.) from 

 the hoopoe. There are no records from British-taken rollers, but 

 one genus Capraiella (Ischnocera) has been found on rollers from 



the continent of Europe. 



This order is represented in Britain by one resident, the kingfisher 

 and three vagrants, the bee-eater, the hoopoe and the roller. The 

 kingfisher is parasitised by two closely related genera of Ischnocera but 

 lacks Amblycera; these two genera are not closely related to those found 

 on any other bird. The kingfisher is a case where the Mallophaga 

 throw no light on the relationships of the host, but the feather lice 

 found on the three vagrants mentioned above suggest that they are 

 related to the Passeriformes. 



Piciformes 

 Genera of Mallophaga recorded in Britain : Menacanthus (Ambly- 

 cera); Briielia, Penenirmus (Ischnocera). 



The species of Mallophaga found on the British woodpeckers 

 belong to genera also found on the passerine birds, which tends to
