seen at Lanesboro, Minn., and either winter residents or very early 

 migrants were seen at New Cassel, AVis., January 27. From the records 

 for the spring of 1885 it is easy to trace two routes and times of migra- 

 tion. The first was along the Mississippi Elver. The enormous num- 

 bers which roosted at Saint Louis, Mo., March 2, began to decrease 

 rapidly after March 4. At Excelsior, Minn., they arrived March 1 ; at 

 Minneapolis, Minn., March 7 and March 9 (two observers); at Elk 

 Eiver, Minn., March 14; Saint Cloud, Minn., March 11, and White Earth, 

 Minn., March 20. The second line of migration was over the prairie 

 along tbe valleys of the Missouri Eiver and the Eed Eiver of the North. 

 The first came to Emmetsburgh, Iowa, March 26; Grand View, Dak., 

 March 30; Eochester, Minn., March 31; Argusville, Dak., March 31; 

 Menoken, Dak., March 31 ; and probably also on the same day to Moor- 

 head, Minn, (latitude 4G° 5G'); for although I saw none there until the 

 next day, yet their abundance then (about two hundred being seen) 

 would indicate that some of them had come the day before (March 31). 

 On this same migrating route they reached Two Eivers, Manitoba, 

 April 2, and Shell Eiver, Manitoba, April 3. They were reported from 

 Oak Point, Manitoba, March 28, and Ossowo, Manitoba, March 29; 

 which fact seems to indicate that the crows which appeared at these 

 two places had come by way of the Mississippi Eiver. Continuing the 

 comparison between Oak Point and Shell Eiver, we find that although 

 Shell Eiver is half a degree farther south the average date of arrival 

 was later than at Oak Point. Out of fourteen of the more common 

 birds which were reported by both stations, two arrived at both places 

 the same day, three came to Shell Eiver an average of three days 

 earlier than to Oak Point, and nine came to Oak Point an average of 

 five days earlier than to Shell Eiver. 



In the fall of 1885 the Crows began to go to roost in numbers at 

 Saint Louis, Mo., September 24; the bulk arrived October 27, and very 

 many were present November 1. 



Mr. Lloyd states that in the eastern part of Concho County, Tex., 

 Crows breed in colonies early in May. 



490. Corvus ossifragus Wils. [283.] Fish Crow. 



The home of the Fish Crow is in the South Atlantic and Gulf States, 

 where it is resident, especially along the coast. It is common in south- 

 ern Louisiana. 



491. Picicorvus columbianus (Wils.). [284.] Clarke' s Nutcracker. 



Dr. Agersborg furnished the only record from the observers for this 

 Eocky Mountain bird, he having taken it as an accidental visitant at 

 Vermillion, Dak., in October, 1883. Professor Aughey saw it once 

 in Nebraska. 



492. Cyanocephalus cyanocephalus (Wied). [285.] Maximilian's Nutcracker; 



Pinon Jay. 



A rare visitant from the Eocky Mountain region. October 23, 1875, 

 three specimens were killed near Lawrence, Kans. (Snow).
