along with the rest of my Tubinares when that group was being 

 arranged by Mr. Salvin. This skin is the type of (Eatrelata 

 hypoleuca (Salvin, Ibis, 1888, p. 359), and remained unique 

 until I received an adult and young from Mr. Hoist. The 

 soft parts of the adult are described as follows : — " Tarsi 

 bluish pink; bill black; irides dark brown; pupil blue/' 

 These skins were obtained on the 16th of June on Nakondo- 

 Shima, one of the Parry group of the Bonin Islands. The 

 young bird is moulting from its downy stage into the adult 

 plumage, and appears not to have left the nest. 



Nycticorax crassirostris. 



Mr. Hoist has been fortunate enough to procure an example 

 of this much disputed species. It is a female with very short 

 crest, and was obtained on Nakondo-Shima, one of the Parry 

 Islands, on the 15th of June. 



The Bonin Night Heron was originally discovered by 

 Captain Beechey during the voyage of the ' Blossom ' in 

 1827, but was not named until 1839 (Vigors, Zool. Captain 

 Beechey's Voyage, p. 27). In the meantime it was redis- 

 covered in 1828, and identified, in 1833, with Ardea cale- 

 donica (Kittlitz, Kupfertafeln zur Naturgeschichte der Vogel, 

 pt. iii. p. 27). Vigors's type was once in the Museum of the 

 Zoological Society, and was transferred to the British Mu- 

 seum, where it now is, all assertions to the contrary ( Walden, 

 Trans. Zool. Soc. ix. p. 238) notwithstanding. 



The Bonin Night Heron is vinous grey above and white 

 below; the head and crest are black, and the occipital 

 plumes, what there is left of them, appear to have been 

 white. The superciliary streak is white, and the axillaries 

 are white. The soft parts are described as follows : — " Tarsi 

 light yellow, with greenish scales in front; bill black, green- 

 ish yellow at base ; irides light yellow." Wing from carpal 

 joint 11 inches; tail 4'3 inches ; bill, from frontal feathers, 

 2*8 inches; tarsus 3*3 inches ; middle toe with claw 3 inches ; 

 height of bill at nostrils *9 inch. 



It appears to be quite distinct from Nycticorax manillensis, 

 which has reddish axillaries and a rufous superciliary streak ;
