nura, and are largely blotched on the thick end with chestnut. 

 Length 1*05 inch; breadth 0'75. 



4. ZOSTEROPS LATERALIS (Lath.). 



Eggs only of this species are in the collection ; but Mr. Travers 

 informs me that the bird is common on all the islands. 



5. Sphenceacus rufescens, Buller. 



Several specimens, two of which are variegated with white 

 feathers, principally on the wings. It is found only on the 

 Island of Mangare. 



6. Gerygone albofrontata, Gray ? 



Above olivaceous brown ; over the eye, region of the ears, and 

 all the lower surface white, tinged with yellow on the flanks, 

 abdomen, and vent. Quills brown, narrowly edged on the outer 

 margin with olivaceou^s ; secondaries the same, but with a broader 

 edging. Tail brownish rufous, with a brownish-black band near 

 the tip, followed on the three outer feathers with a band of pale 

 rufous; tip brown. Iris light red. Length 4*5 inches ; w^ing 

 2*25 ; bill from gape 0*65 ; tarsus 0*87. 



Egg pinkish white, with numerous red spots and lines. 

 Length 0-74 inch ; breadth 0-54. 



Hub. All the islands. 



Two specimens, neither in good condition, were all that Mr. 

 Travers brought. This bird differs from Gray's description 

 of albofrontata, in the ' Voyage of the Erebus and Terror,' 

 remarkably in size, and also in the colour of the tail; but I 

 notice that although the total length and that of the wing are 

 considerably more in Mr. Gray's bird than in mine, still the bill 

 and the tarsus are smaller ; and the coloration of the tail in the 

 figure agrees with the Chatham-Island bird, although the de- 

 scription does not. Mr. Gray's bird is also said to have been 

 brought from New Zealand by Dr. DieiFenbach ; but as this spe- 

 cies has never been found in New Zealand since, and as Dr. 

 Dieffenbach visited the Chatham Islands, it is possible that the 

 label may have got misplaced*. 



7. Petroica dieffenbachi. Gray. 



A single male specimen is in the collection. It answers
