570 PROCEEDINGS OF THE NATIONAL MUSEUM vol. no 



I am indebted to Air. Elbel for submitting the Thai Anoplura 

 collection for study and deposit in the collections of the U.S. National 

 Museum. Ernestine B. Thurman and the late D. C. Thurman, Jr., 

 kindly donated their collections of Thai Anoplura, which have served 

 as a valuable supplement to Mr. Elbel's collections. 



As dictated by the distribution of its hosts, the Thai anopluran 

 fauna is mamly attributable to the Oriental Region, but contains 

 elements from the Palaearctic and Australian Regions as well. One 

 of the species, Polyplax spinulosa (Burmeister) , has a cosmopolitan 

 distribution on Rattus species. 



Probably at least half the species of rodent-infesting Anoplura in 

 Thailand have now been collected. The Anoplura of the primates 

 and ungulates in Thailand remain completely unknown, and those 

 from all the surrounding areas are very poorly known. 



The description of a new species of Neohaematopinus taken from a 

 flying squirrel from Borneo is included in this paper because this 

 species is very closely allied to one taken from Thai flying squirrels. 

 I am indebted to Lt. Col. Robert Traub, M.S.C., U.S. Army, for 

 donating the specimens from Borneo. 



David H. Johnson, curator of mammals, U.S. National Museum, 

 determined the hosts reported in this paper. Skins and skulls of 

 these mammals are in the collections of the Division of Mammals. 

 I wish to thank Dr. Johnson for his very necessary and helpful coop- 

 eration. 



Unless otherwise indicated, all the specimens reported are from 

 Thailand. If there are only two elements in a locality name, they 

 represent the province and the village (Ban) or mountain. If three 

 or more elements are included, they represent the province, the district 

 (Muang), and the village or sub village or mountam. Provincial 

 names are given in small capital letters. Transliteration of the names 

 foHows the U.S. Army Gazetteer for Thailand (1944) with emenda- 

 tions by H. G. Deignan. 



Collector's names (Elbel and his associates) have been omitted 

 except in data pertaining to the holotype of each of the new species. 

 Individuals and organizations who cooperated with Mr. Elbel in 

 obtaining the material were: Boonsong Lekagul and H. G. Deignan; 

 and the Banpong Plague Laboratory, the Khorat Plague Laboratory, 

 and the Nakhon Sawan Plague Laboratory.
