gives the length of villosus as 8.50 to 9 inches and wing 4.50 to 

 5.00, and the length of leucomelas as 10 to 11 inches and wing as 

 5.02 to 5.40. Four of the six we observed were secured and meas- 

 ure as follows : 



Oct. 18— male— 10.20xlG.63x5.25. 



Nov. 7— male— 10.12x16.50x5.12. .^.

Jenkins gives the wing average of 5 male JeucomeJas as 5.1G anti,« 



6 male villosus as 5.00. 



20. DryoTjates puhescens medianus. — Downy Woodpecker, 

 pair was seen in the second growth along Hubbard lake on Oct 

 ber 15 and another in the same locality on the 18th. All three were 

 working west along the south shore, 



21. Picoides arcticus. — Arctic Three-toed Woodpecker. In the 

 northwest corner of the hardwood are some hemlock trees and 

 among these we discovered a female of this species on November 

 11. It allowed a close approach, but upon taking wing passed 

 entirely from the woods in a southerly direction. This was our 

 last day afield and as we did not meet with it earlier it may have 

 been the first of a migration from the north. 



22. Otocoris alpestris alpestris. — Horned Lark. The height and 

 barren appearance of the ridge supporting the dwelling section of 

 Lincoln was doubtless an attractive land mark for both forms of 

 this lark and the pipits as none were seen elsewhere during our 

 entire stay. There was a gravel outcropping and a bean field that 

 few larks could pass without alighting. All of the Horned Larks 

 came from almost due north and departed towards the south. The 

 migration began with a floclc of twelve on October 30 and from 

 seven to twelve were noted daily until November 5, when we 

 counted forty in one flock, and this was the last of them. Six 

 individuals were secured, and .comiDaring with four winter speci- 

 mens from Rhode Island we find but one of the latter with the 

 sulphur yellow of equal brightness on chin, throat, forehead and 

 line over the eye. 



23. Otocoris alpestris praticola. — ^Prairie Horned Lark. Three 

 birds of this form were seen on the gravel slope on October 7 and 

 about 25 on the following day. They were carefully inspected and 

 the one questionable example secured. This was a male with 

 throat, cl]iu and forehead sulphur yellow and could not have been 

 identified without the bird in the hand. During the month it was 

 necessary to take two more for the same purpose and the three 

 specimens of this form and six of the alpestris were all that we 

 required to fix the status of the two be.vond all question. About
