1. Nesospiza goughensis. (Plate VI. fig. 2.) 



Nesospiza goughensis, Eagle Clarke, Bull. Brit. Orn. Club, 

 xv. p. 18. 



This species possesses the essential characters of the genus 

 Nesospiza as propounded by Cabanis (Journ. fur Orn. 1873, 

 p. 154). It is a larger bird than the type (N. acunhce) ; it has 

 a longer and more slender bill, in which the culmen is more 

 arched and the keel of the mandible straighter; and the 

 third primary is slightly the longest. 



Adult Male. General colour bright olive-green, slightly 

 washed with silvery grey ; centre of abdomen, under tail- 

 coverts, a stripe from the forehead over and behind the eye, 

 and a malar stripe olive-yellow ; chin, throat, and lores 

 black; primaries and secondaries slate- grey, with silvery- 

 grey tips and bright olive-green margins, and their under 

 surfaces broadly margined with silvery grey on the inner 

 webs; under-wing-coverts grey washed with yellowish 

 green ; central pair of rectrices olive-green, the rest grey 

 edged and slightly washed with green. Bill and feet, in 

 life, clove-brown. Wing 4*15 inches, tail 3*68, tarsus 1*18, 

 culmen "71. 



This is probably the summer plumage. 



Adult Female. Resembles the male, but is not so brightly 

 coloured, being dull green. Chin, throat, and lores dusky, 

 and, with the buff stripes over the eye and on the malar 

 region, inconspicuous ; feathers of the back and outer 

 margins of secondaries slightly fringed with reddish brown ;
