126 BULLETIN OF THE 



the Kaw River, in company with Cotyle riparia, entering the holes in the 

 bank in company with that species, and also sitting in the mouths of the 

 holes. One was shot as it left a hole, so that there is no reason for 

 doubting the observation. They had the same appearance of breeding 

 in the banks as Cotyle riparia themselves. 



3G. * Cotyle riparia. Exceedingly abundant, especially at Topcka. 

 Hundreds of them were excavating their holes in the bluffs of the Kaw 

 River, May 15th to '20th, but had not yet commenced to lay. At least no 

 eggs were found in any of a considerable number of nests examined. 



3 7. * Cotyle serripemiis. Common. They appear to breed either 

 singly, or a few pairs together, and not in large colonies like Cotyle riparia. 

 They were excavating their holes, but had not yet laid. 



38. *Progne subis. Common at Topeka, and abundant at Leaven- 

 worth, breeding in boxes provided for their use. 



VIREONIDJE. 

 30. * Vireo olivaceous. Common. 



40. Vireo gilvus. Common. 



41. Vireo flavifrons. A single specimen was shot at Topeka, and 

 several others were seen. 



42. * Vireo noveboracensis. Common. 



43. * Vireo Belli. Exceedingly abundant after May 15th at Topeka; 

 not seen earlier. Commenced pairing immediately after their arrival, and 

 were one of the most numerous and conspicuous species of the smaller 

 birds. 



AMPELIDJE. 



44. * Ampelis cedrornm. Several small roving flocks were seen at 

 Topeka, May 20th and later. 



LANIIDJE. 



45. * Collurio ludovicianus. Said to be moderately frequent, but 

 seen only at Leavenworth.* 



* Messrs. Dresser and Sharpe, in a paper on " Lanius excuhitor and its Allies " (Proc. 

 Zool. Soc, 1870, p. 595), combine C. exciilitoroides and C- elegans with C. ludovicianus, 

 their conclusion being based upon an examination of specimens of each of these so- 

 called species. I am glad to find my own opinion on this point (first partially expressed 

 in Ainer. Nat., 1869, p. 579, and more fully reiterated in Bull. Mus. Comp. Zool., Vol. 

 II, p. 270, April, 1871) thus confirmed. 



The original specimen of the C- elegans (Lanius elegans of Swainson), now in the 

 British Museum, these gentlemen refer to the L. laktora of Northeastern Africa and Asia, 

 presuming the specimen to have come from some other locality than North America, or 

 that the /.. lahtora may occur in North America as n straggler from Northern Siberia. 

 In this connection I may add that I have been long impressed with the close resemblance
