A few words in regard to the distribution of Mallophaga col- 

 lected would probably be interesting. It was found that birds 

 belonging to genera not strictly tropical, and fj>und principally 

 in the higher altitudes, were much more often infested with the 

 parasites than those strictly tropical and inhabiting the lower 

 altitudes. This statement, however, is only true in a general 

 sense, but when exceptions were encountered it was usually 

 found that the parasites belonged either to the genus Menopon or 

 Colpocephalum, and were present in great numbers, these two 

 genera, especially the latter, having been taken in large numbers 

 on strictly tropical birds. 



The list of Mallophaga collected on Tiiianius robiistus is a very 

 interesting one, including two new genera and several new species, 

 all of which are very aberrant forms of the genera in which they 

 have been placed. Other very interesting forms are Colpoce- 

 phalum extraneum sp. nov. and mirabilc sp. nov. collected on 

 Nyctidromns alhicoUis and Zarhynchus ivagleri, in that they pos- 

 sess a very marked mesothoracic suture and have the metathorax 

 enormously developed posteriorly. It seems to me that many of 

 the present genera need a thorough revision and that some of 

 them should be split up into two or more genera or sub-genera, 

 Colpocephalum, Menopon, and Physostomnui especially needing 

 it.
