quently, however, the common name can be associated accurately with 

 only a generic, familial, or even ordinal name. There are some instances 

 where an ordinal association could not be made accurately, so the cate- 

 gory, "uncertain position", is used for such citations. Examples are 

 "casaco de couro" or "ferreiro" of Lent (1935) and "siroli (in Bihar)" 

 of Fletcher (1920). 



Alphabetical sequence is used in both check-lists beginning with or- 

 dinal names through familial, generic, specific and including subspecific 

 names. The entomological check-list is headed by an "undetermined" 

 category and is ended by a section on "general entomological referen- 

 ces". The ornithological portion has at its beginning several categories 

 of broader scope than the ordinal designations which follow. These 

 extra-ordinal groups, which follow the beginning "undetermined" cate- 

 gory, are "birds of prey", "nests in burrows", "marsh birds", "sea 

 birds", and "waterfowl". These are arbitrary groupings established to 

 preclude placing their contents in undetermined and uncertain position 

 status, since they could not be assigned accurately to order on the basis 

 of information accompanying them. "Uncertain position" and "general 

 ornithological references" terminate the ornithological check-list.
