ALBATROSS EXPLORATION, BIRDS— R1DGWAY. 



No. 115965 is apparently a female, and is in transition immature plum- 

 age, the brownish chestnut of the neck being interspersed with white 

 feathers. 



The third example (No. 116297) is a young bird, probably a male, 

 of the preceding year, and agrees exactly with a specimen from Cali- 

 fornia. In this the sides of the under mandible are mainly blackish, 

 becoming orange-reddish terminally and whitish basally ; the pouch 

 light brownish basally, as in the preceding. 



The measurements of these specimens are as follows : 



Family SULID^. . 



32. Sula gossi Ridgw. 

 t Sula cyanops Salv. Trans. Zool. Soc. London, ix, pt. ix, 1576, 496. 

 ? Dysporus cyanops Sundev. P. Z. S., 1871, 125. 



Chatham Island, one specimeu. This example I am unable to dis- 

 tinguish from the types of 8. gossi. Its measurements are as follows: 

 Wing, 17.50; tail, 10.00 (graduated for 4.70); culmen, 4.55; depth of 

 bill at base, 1.37 ; tarsus, 2.30; middle toe, 3.05/ 



Family ARDEIDJE. 



33. Ardea herodias (Linn.) ? 



Duncan Island, one specimen. 



I am not quite satisfied of the absolute identity of this. bird with the 

 true A. herodias, but the single specimen in the collection being not 

 fully adult a satisfactory comparison can not be made. 



34. Butorides plumbeus (Sundev.). 



Hood Island, three specimens ; James Island, two specimens ; Dun- 

 can Island, one specimen ; Abingdon Island, one specimen. 



There is much variation in intensity of coloration among the adults 

 in this series, but since the two specimens from James Island represent 

 nearly the extremes, it is probable that the variation is of au individual 

 character. 



35. Nycticorax pauper Scl. and Salv. 

 Hood Island and Indefatigable Island ; two specimens. 



Family PHCENICOPTERID^F. 



36. Phoenicopterus ruber Linn. 

 James Island, two specimens; Charles Island, four specimens. 

 After very careful comparison, I am unable to find any constant dif- 

 ference between these birds and examples of P. ruber from Florida,
