Materials. — Of the four species admitted as valid in the following 

 pages, I have examined approximately 218 specimens, the majority 

 of which were obtained either by me or by Leslie Hubricht. Some 

 additional material, including type specimens, was examined either 

 at the particular museum or by loan from several museum collections, 

 all of which are indicated by the following abbreviations : 



AMNH — American Museum of Natural History, New York 



ANSP — Academy of Natural Sciences, Philadelphia 



MCZ — Museum of Comparative Zoology, Cambridge 



RVC — R. V. Chamberhn collection, University of Utah, Salt Lake City 



USNM — United States National Museum, Washington 



The adequacy of any revisionary work on mUlipeds is known to be 

 largely a direct result of the study of typical material. I have been 

 fortunate in being able to see some kind of type for all but one of the 

 names of the foregoing list. 



holotypes paratype 



Aporiaria geniculata (RVC) Fontaria stricta (USNM) 

 Aporiaria deturkiana (ANSP) topotype 



Nannaria media (MCZ) Aporiaria Carolina (RLH) 



No typical material of Aporiaria brunnior has been seen ; this name 

 is allocated tentatively on the basis of its published description. 



Friends and colleagues who kindly loaned specimens from collections 

 under their care or who permitted the examination of material at 

 various museums include the following: Ralph E. Crabill, Jr., P. J. 

 Darlington, W. J. Gertsch, and J. A. G. Rehn. I owe a particular note 

 of thanks to Dr. Ralph V. Chamberlin for his generous loans of type 

 specimens and to Prof. Max Vachon, who kindly exchanged a male 

 paratype of Fontaria stricta from the Museum National d'Histoire 

 Naturelle de Paris. 



Much of my field work, prior to 1962, was made possible by finan- 

 cial assistance from the Highlands [North Carolina] Biological Station. 

 I am under a continuing debt to numerous friends who have assisted 

 in collecting or who independently have picked up millipeds for me. 

 The name of Leslie Hubricht continues to head this roster. 



Drawings have been made with a binocular microscope fitted with 

 an ocular recticule. Measurements of length were taken to the nearest 

 whole millimeter; those of width, to the nearest tenth of a millimeter 

 with a vernier-scale calipers.
