Distribution and Species-forming among Ectoparasites. 

 (The paper is printed elsewhere. — Editor.') 



Systematic position of the Mallophaga. Structure and life- 

 history. Owing to conditions of comparative isolation there is 

 an absence of the work of external influence, promoting wide di- 

 vergence, generic and family distinctions thus tending to be few. 

 whilst specific and varietal differences are numerous. Review 

 of the orders of birds, with the numbers of their mallophagan 

 parasites. Tendency of a single parasite species to be common to 

 two or more related host species. Evidence that parasite species 

 have been handed down almost unchanged, through a long line of 

 host evolution. Species formation of Mallophaga has depended 

 mainly on inheritance and isolation. In contrast to the usual 

 conditions of insect biology, adaptation has played a subordinate 

 part. Consequent exceptional interest of this group of parasites. 



The President having expressed the general appreciation of 

 Prof. Kellogg's paper, the meeting proceeded to discuss 



General Business. 



The President, in calling upon the chairman of the Executive 

 Committee to read his report, said they had several matters to 

 decide, and it would be most expedient if the various points 

 brought forward in the report were discussed separately. 



K. Jordan then read the following Report of the Executive 

 Committee : 



Mr. President, the Executive Committee has the honour of 

 laying before this General Meeting four propositions, and asking 

 its decision thereon, concerning : 



(i) The organisation of an Entomological Committee on 

 Nomenclature ; 



(2) A Resolution of the Section on Economic and Pathologic 

 Entomology ; 



(3) The election of some additional members of the Per- 

 manent International Committee of Entomologists; 



(4) The election of Honorary Members of the Entomological 

 Congress — and
