records and credited them to Wyoming. Later he neglected to make 

 the necessary changes, and several appear in the printed volume with 

 the wrong localities. 



Thirty years later, 'The Birds of Wyoming' was published as Bulletin 

 No. 55 of the Wyoming Experiment Station. Throughout this Bulletin, 

 all of the Holden and Aiken notes are used as pertaining to Wyoming, 

 and in addition some of the erroneous records are copied from ' Birds of 

 the Northwest.' 



There are twenty-six species whose standing is not changed by the 

 mistake, and it is only necessary to strike out the words "found by Aiken 

 at Sherman." The records of eighteen other species are more seriously 

 affected. 



The quotation under Myiarchus cinerascens is one of the Coues mistakes, 

 and so also under the same species, the reference to a note by Aiken on 

 the occurrence in Wyoming of Myiarchus crinitus. There never was any 

 such note. 



The Aiken record of Aphelocoma woodhousei should be omitted, and 

 also one of the Coues records. Two specimens are recorded (Birds of the 

 Northwest, p. 219) as taken in Wyoming, but No. 59864 was really taken 

 in Colorado. The other, No. 61082, was taken October 10, 1870, on the 

 Green River not far from the location of the present town of Green River. 



All the Aiken records should be omitted under the following species: 

 Coccothraustes vespertinus montanus, Carpodacus mexicanus frontalis, 

 Junco hy emalis, Helminthophila celata lutescens, Compsothlypis americana, 

 Sitta pxjgmaia, and Psaltriparus plumbeus. 



The specimens of Leucosticte tephrocotis recorded as taken at Sherman 

 were actually secured there, but not by Aiken. 



The three species, Helminthophila Virginia, Catherpes mexicanus con- 

 spersus, and Regulus satrapa are admitted to the list of Wyoming birds 

 on the strength of the Aiken records, and hence so far as these records 

 are concerned should be dropped from the State list. The Canon Wren 

 has been credited to Wyoming in the latest reviews of the family, but 

 such a statement of range seems to have no valid basis. 



The 'Hypothetical List' of the Birds of Wyoming contains four species, 

 that are said to have been recorded by Aiken in Wyoming. Each of these 

 is really a record for Colorado. The Rusty Blackbird of the Hypothetical 

 List is an error of identification by Holden and should have been the 

 Brewer Blackbird. 



The statement is made, in treating of Dendroica auduboni, that in the 

 ' Birds of Colorado ' this species is said to breed above timberline. What 

 is really said is that the species breeds in Colorado from 7,500 to 11,000 

 feet. The author of the ' Birds of Wyoming' failed to consider that although 

 11,000 feet is above timberline in Wyoming, it is a thousand feet below 

 timberline in southern Colorado. — Wells W. Cooke, Biological Survey,
