former ; but it has a grey-buff tinge on the flanks, as in 

 Z. xanthochroa. Its most distinguishing characteristic how- 

 ever, is, a broad patch of white on each flank ; this is seen, 

 to a less extent, in Z. xanthochroa, but is entirely Avanting in 

 Z. flavifrons. 



" Z. inornata, nobis, is certainly a good species, and can- 

 not be confounded with Z. melanops, G. R. Gr., from the 

 same place. It has no white round the eye ; and its length 

 is 5" 6'", of wing 2" 11"', as against 5" and 2" 4"' of Z. me- 

 lanops. L. L. says it is the most aberant Zoster ops he ever 

 met with, and that its call is a loud whistle, so like that of 

 Pachycephala that he several times pursued and shot it under 

 the impression that it was really one of those birds/'

 (Plate V.) 



The types of this new and interesting Thrush, though fully 

 described by Mr. Layard six months since, are only now 

 received, and are represented on the accompanying plate. 

 There is a young bird in nest ling- plumage, very like a young 

 English Blackbird. To Mr. Layard^s full description I have 

 nothing further to add"^. 



* It may not be out of place to take this opportunity of giving a sjm- 

 opsis of the true Thi'uslies of the Pacific Islands, so far as our present 

 knowledge extends. The researches of Mr. Layard have already doubled 

 the number previously known ; and we trust he may yet further succeed in 

 enlarging the catalogue, especially as he has already been on the traces of 

 two unknown species on the islands of Ambrym and St. Bartholomew, New 

 Hebrides, fi'om which archipelago we have not, as yet, a single species. 



The Pacific Thrushes may be divided into two groups. 



ct. Brown, and generally uniform ; sexes alike. 



/3. The body black, the head and neck frequently of a different colour.

(1) TxrRDUs ULiETENSis, Gm., = T. badius, Forst. 



This, the first described from this region, is not represented, so far as 1 

 know, in any museum. It was obtained during Capt. Cook's voyage at Raia- 

 teia, one of the Society Islands. I have examined Forster's drawing in 

 the British Museum. The species is very like T. xanthojms in colour, but has 

 a brown beak and legs. If it has not been exterminated, we may hope soon 

 to know more of it, as a collector is on his way to that group of islands.
