and young on each day, from the beginning of feeding about 4.30 \. m. to its 

 cessation at about S p. m. without interruption, aggregating 1 1 1 hours and 

 53 minutes. Such cooperation renders studios of this sort much loss irk- 

 some. During tins time the parents fed the young 2373 times and a table 

 shows roughly the different sorts of food that were provided. There was no 

 feeding by regurgitation. The egg shells were devoured by the parents as 

 were the excreta during the earlier part of the nestling period. Later they 

 were carried away. The female did all the brooding and both birds had a 

 stereotyped method of approaching the nest. The incubation period was 

 eleven days. 



This paper will take its place with a number of similar studies that have 

 appeared in reeent years and which we trust may increase in number 

 until all of our common speeies have been similarly investigated. A com- 

 parative study of such records will eventually yield most valuable generali- 

 sations.— V? s 



Stone on Venezuelan Birds. 1 — This paper treats of the birds secured 

 by the Francis E. Bond Expedition of 1911, in the Paris Peninsula and the 

 Orinoco delta, all the collections there secured having been presented by 



Mr. Bond to the Academy of Natural Sciences of Philadelphia. After a 

 summary of the movements of the expedition and some comments on the 

 faunistic relationship of certain of the species found at Cariaquito on the 

 Paria Peninsula, the paper gives an annotated list of the one hundred and 

 seventy-three species collected. As stated by the author " it is not sur- 

 prising that no new forms were obtained. ... in a region so long familiar to 

 bird collectors as the Orinoco delta." although the collection, which com- 

 prises live hundred and four skins, accompanied by full data, is of consid- 

 erable value. "• in view of the lack of definite localities in the ease of early 

 collections made in the Orinoco region." The two regions examined are 

 quite different in character, forty-eight species having been taken at Caria- 

 quito which were not secured in the delta country, although the author does 

 not consider the collection " sufficiently comprehensive to warrant any gen- 

 eral deductions on distribution." Field notes on the coloration of the tarsi, 

 irides and other soft parts, made by Mr. Thomas 8. Gillin who prepared 

 the specimens, and notes on distribution and abundance supplied by Mr. 

 Stewardson Brown, who was also a member of the expedition, add value 

 to the paper.— J. A. G. R.
