ON A COLLECTION OF MALLOPHAGA FROM GUAM, 

 MARIANAS ISLANDS 



By M. A. Carriker, Jr. 



The collection of Mallophaga treated in this paper was made by 

 Lt. Rollin H. Baker during World War II while he was a member of 

 the U. S. Naval Medical Research Unit No. 2, assisted by other 

 members of the unit. The birds from which the lice were collected 

 are in the United States National Museum, and their correct names 

 were furnished me by Dr. Herbert Friedmann, curator of the Muse- 

 um's division of birds. 



Though small, the collection is an interesting one, for it represents 

 the first time any Mallophaga have been taken from birds indigenous 

 to the island of Guam. Twelve species of birds are represented among 

 the hosts, four of which are sea birds (not indigenous) , one is an intro- 

 duced form (Streptopeliabitorquata dusumieri),Sind the remaining seven 

 are indigenous. The correct determination of the Mallophaga in- 

 volved has, in some instances, been diflBcult, since the pertinent 

 material is in various museums in Europe; in these cases it is possible 

 that errors have been made. The drawings were prepared by the 

 author. AH measurements are in millimeters. 



Suborder ISCHNOCERA 

 Family PHILOPTERIDAE 



CORVICOLA, new genus 



Genotype. — Corvicola insulana, new species. 



This genus is close to Rallicola Johnston and Harrison as now de- 

 fined. It seems to contain some very aberrant forms, such as R.
