 settled sense.' The color of yEstrelafa carihhcca might well have been 

 described by them as russet.

This communication was followed by another " Memorandum " 

 from Doctor Stejneger, addressed to Dr. F. W. True, and dated Jan- 

 uary 2, 1908; it read as follows: 



" As requested by you, I have gone over Mr. Mowbray's material 

 with Dr. Richmond, and came essentially to the same result as he, 

 viz., that the bones belong to an undescribed species of JEstrelata 

 having the size of ^. carihhcca and the coloration of the somewhat 

 larger ^. hasitata. This of course under the supposition that the 

 bones belong to the ' Cahow ' as described by the early colonists. As 

 for the ' russet ' color, I am of the belief that the colonists by this 

 designation meant the brownish-grayish color so characteristic of 

 these birds. As Mr. Mowbray is said to have some feathers of a 

 'russet' color, he may be able to throw some light on this question, 



" Dr. Richmond thinks that probably Mr. Mowbray himself might 

 want to publish the matter, as he has only asked the Museum to 

 identify the material. 



" Respectfully, 



[Signed] Leonard Stejneger." 



Doctor Richmond, in his letter of November 29, 1913, set forth 

 above, gives a list of the material representing these subfossil birds 

 of Bermuda belonging to the U. S. National Museum. I find this list 

 substantially correct, so it is unnecessary to duplicate it here; it will 

 be described further on in the present paper. 



A short time after the bones from the American Museum of Nat- 

 ural History, and those forming the collection of Mr. McGall, were 

 in my possession, I separated, in the case of both^ the various bones 

 into groups, placing all the skulls together, all the vertebrae, all the 

 different long bones, ribs, digits, and so on. After this had been 

 accomplished with the greatest care, I prepared two lists of the mate- 

 rial as follows:
