This little bird has a greater interest for us on account of its 

 remarkable resemblance to our Sylvia trochilus. I have only 

 seen the above-described specimen, and can say nothing else 

 about its way of living than that even in its actions it has an 

 extraordinary resemblance to Sylvia trochilus, so that I fully 

 believed I had found that species until an examination of its 

 flattened, much broader beak, and the somewhat different-formed 

 wings proved my mistake. These are the only points in which 

 the genus Acanthiza (Vig. et Horsf.) differs from our Sylvia ; the 

 beak is even unlike that of our S. hippolais. In New Holland 

 there are several species to be found. I heard no note from the 

 bird described. This is most likely the kind to which those authors 

 allude who speak about the Indian Sylvia trochilus (for example, 

 Edwards in the text to plate 278). 



19. Acanthiza arrogans, n. Superne olivaceo-viridis, subtus tota 

 flava ; vertice vittis 2 longitudinalibus nigris e rostro ad nucham. 



<£ Calcutta, 9 Febr. Corporis latera flava. Ala? fuscae, plumis 

 virescenti-marginatis ; pennis intus albidis. Rectrices utrinque 2, 

 pogonio interno e medio ad apicem albo, omnes rectae, apice angu- 

 latae, unde cauda emarginata. Rostrum superne fuscum et pedes 

 albidi. Magnitudo et statura Reguli. Longit. 4 poll. ; ala 57 mill., 

 tarsus 17, rostrum e fronte 10 ; altit. 2, latit. 4. Rostrum apice non 

 compressum, maxillis aequalibus, superioris apice non deflexo. Re- 

 migum l a paullo breviorquam in praecedente ; 5 a reliquis sublongior. 

 Lingua sat magna, apice rotundata, integra. 



This bird bears a considerable resemblance to our Regulus. I 

 have met with it only twice, amongst bushes, in which it hopped 

 about without being shy. The specimen described hopped ac- 

 tively about in a low tree without concealing itself, and screamed 

 a rough tshack ! tshack ! as if it intended to drive me away. I 

 could not find out how far it had begun to build its nest. In its 

 stomach I found only small hard beetles. This bird also is called 

 by the natives Tuntuni.
