This peculiar species, as the above records show, is abundant on its 

 special host. A new genus will ultimately be required for its reception. 



Eric Mjoberg, " Studien iiber Mallophagen and Anopluren ' 

 (Archiv for Zoologi. Band. 6, N : O. 13, p. 108, Upsala and Stock- 

 holm, 1910), remarks, "Von dieser sehr charakteristichen 'Art, die 

 nur einmal und zwar Von Piaget, in der Literatur Erwahnung 

 gefunden hat, liegen mir einige Exemplare von deniselben Vogel, 

 Sphaeniscus magellanicus, vor, (Afrika, Kaudern)." 



[Sphaeniscus magellanicus, specifically different from S. demersiis 

 is not found on the African coast. Either Mjoberg's specimen was 

 badly identified, or the locality "Afrika " is wrongly given. EDITOE.]

GIEBELIIDAE, fain. nov. 



We erect this division for these forms, hitherto included amongst 

 the Philopteridae, which are furnished with a broad transverse flap 

 on the under side of the clypeus. This flap projects to form 

 characteristic horns or knobs at the sides of the clypeus. 



Only three genera are certainly to be placed here at present 

 Giebelia, Kellogg, Mackayia, Waterst., and Philoceanus, Kellogg ; 

 Giebelia and Mackayia apparently represent a line of direct de- 

 velopment, of which three stages are to be seen in G. mirabilis, 

 M. dimorpha, and M. heteracanthus ; Philoceanus is a more isolated 

 form which we have not seen. 



It may be possible later to diagnose this family more fully. Prob- 

 ably the definition should include the peculiar banding and 

 chaetotaxy of the head, etc. Meanwhile the membranous folded
