 shape of the posterior wings and on the underside in the shape of the central band. 



12. Mycalesis persa sp. nov. 



Male. — Upperside. : differs from M. perseus Fabr. in both wings being more 

 rufous brown, and in the ocellus on the upperside of the anterior wings being larger 

 and surrounded by a bright rufous ring. 



On the underside there are only two ocelli on the anterior wings, one near the 

 apex, the other between the two lowest median nervules, each surrounded by a pale 

 brown outer ring; the pale streak which crosses these wings is much more obscure 

 and nearer to the ocelli than in M. perseus. On the jiosterior wings the pale streak 

 is Likewise more obscure and nearer to the row of ocelli, and instead of being straight, 

 as in M. perseus, it curves outwardly between the lowest subcostal and upper median 

 nervules. 



The /emaZe differs from the male in being paler and the ocellus on the uiipcr- 

 side of the anterior wings being larger. 



Expanse of wings : If inch. 



Hab. Dili (Timor). 



A series of seven specimens, none of which differ from the type. 



NOTE ON THE STEPHENS ISLAND ROCK-WEEN 

 TBAVEIiSIA LYALLI Rothsch.' 



By the HON. WALTER ROTHSCHILD. 



WHEN I described this very interesting bird {Bidl. B. 0. C, December 29th, 

 1894), although I had nine specimens before me, nothing was known of its 

 habits. It has since been re-described by Sir Walter L. Buller in the Ibis (April 

 1895), under the name of Xenicus insularis, but the author gives us no further 

 particulars, except that the three specimens were Isrought in by the cat. Now I have 

 had a letter from Ur. Henry Travers, who tells me that all the eleven specimens (ten 

 in my Museum, and the one from which Sir Walter Buller made his description) 

 were brought in by the cat. The bird itself has only been seen on two occasions 

 alive, when disturbed from holes in the rocks, and was not obtained. It is nocturnal, 

 runs like a mouse and very fast, and did not fly at all.
