lection that were taken in the fall of the year on the Laramie 

 Plains. 



69. Sterna caspia Nutt. 



Forster's Tern. 

 Migratory; rare. Apparently a rare bird in Wyoming; 

 and has been reported only from the southeastern corner of 

 the state. Mr. Bond reports it from Cheyenne and Dr. Jesurun 

 from Douglas. I would naturally expect to find this species 

 as a summer resident. 



70. Sterna hirundo Linn. 



Common Tern. 



Migratory; rare. Two, specimens were taken by McCar- 

 thy on Horse creek, Sweetwater river, 1859. It has also been 

 taken at Cheyenne by Bond. 



yy. Hydrochelidon nigra surinamensis (Gmel.). 

 Black Tern. 



Migratory; rare. Williston reports taking this bird on 

 May 20, 1879, at Como lake. Bond has taken it at Cheyenne, 

 and I have seen what I concluded must be this species at Hut- 

 ton's lake in November, 1898. Dr. Jesurun has seen this spe- 

 cies at Douglas. 



CORMORANTS. 



119. Phalacrocorax carbo (Linn.). 



Cormorant. 

 Probably accidental. There is but one recorded for Wyo-

120. Phalacrocorax dilophus (Swain.). 



Double-crested Cormorant. 



Summer resident ; rare. A single specimen was taken from 

 a small lake in the Clear Creek valley just west of Buffalo in 

 July, 1897. This was a female and judging from her actions 

 had a brood at some place about the lake. This specimen is
