1877. Ridgway. MaxweWs Colorado Museum. Field 

 and Forest, II. 1876-7, pp. ig£ and 208. This is the finest col- 

 lection ever made of Colorado birds. It has been claimed that 

 every bird in this collection was actually taken in Colorado. 

 There seems good and sufficient reasons for believing that some 

 of the skins bought by Mrs. Maxwell were really taken outside 

 the State. They were all mounted by Mrs. Maxwell and largely 

 collected by her. Most of them were taken in the vicinity of 

 Boulder, but many were sent to her by friends in other parts of 

 the State. Unfortunately nearly all of the data accompanying 

 these specimens have been lost and there is now no means of 

 ascertaining when or where they were captured. 



Besides the species already given from this collection in 

 Ridgway's List there are the following: stercorarius parasiticus, 

 rissa tridactyla, larus Philadelphia, xema sabinii, phalacrocorax 

 dilophus, mergus serrator, clangula islandica, oidemia americana, 

 anser . albifrons gambeli, olor columbianus, tantalus loculator, 

 nycticorax violaceus, charadrius squatarola, asio accipitrinus, 

 nyctala acadica, megascops asio maxwellicB, megascops flam- 

 meola, coccyzus americanus occidentalis, leucosticte tephrocotis 

 littoralis, calcarius lapponicus, vireo solitarius cassinii. Two 

 of these, rissa tridactyla, and nycticorax violaceus, still remain 

 the first and only records for Colorado. 



This completes the record of all work done in Colorado by 

 the government surveying parties and by the individual workers 

 that did so much for the ornithology of the state from 1869 to 

 1876. The state list at this time numbered 279 species or two 

 more than those included ten years later by Mr. Drew in his 

 list of Colorado birds. The Maxwell collection is the last large 

 addition to the Colorado list. The 81 species that have since 

 been added are nearly all rare or accidental visitants and have 

 been added a few at a time by a large number of difierent 

 workers.
