Mr. Gregory M. Mathews sent the following description 

 of a new subspecies of Collocalia : — 



Collocalia francica yorki^ subsp. n. 



Differs from C. f. terrceregirKB (Ramsay) in lacking the 

 whitish rump, in being darker below, and in having the bill 

 bigger and broader. 



Type : Peak Point, Cape York, Queensland. Collected 

 on 10th September, 1913, by Mr. Robin Kemp (No. 18188 

 in my collection) . 



(To be added to p. 152 of my 'List of the Birds of 

 Australia.') 



Capt. C. Ingram exhibited three eggs of the Cocoa 

 Thrush {Turdus fumigatus Licht) from Trinidad, and 

 communicated the following remarks : — 



Comparatively little is known of the breeding-habits of 

 the majority of Trinidad birds, and well-authenticated 

 eggs from this island are rare. This is partly explained 

 by the dearth of competent collectors, but also by the 

 density of the vegetation and the extreme variability 

 and uncertainty of the breeding-season, which appears to 

 extend over a large portion of the year. For instance, on 

 December 27th I was shown the nesting-hole of a Dendro- 

 colaptine species containing yoang about ten or twelve days 

 old, although (as I was locally informed) the nesting-season 

 would not be at its height until about March. 



It was only by chance that I discovered the nest of that 

 comparatively rare bird the Cocoa Thrush. I was hunting 

 deer in the early morning of December 29th and had just 

 pulled my horse up at the corner of a forest-track when I 

 noticed a reddish-brown bird settle in front of me. It 

 hurriedly gathered a beak-full of clay from the wet bank 

 and then disappeared again into the bush. This performance 

 was repeated several times, so that I was finally able to 

 follow the bird to a mango-tree growing at the edge of a 

 cocoa-plantation under .a very steep, forest- covered slope. 



On January 8th I re-visited this tree and was pleased to 

 find that the nest now contained three handsomely-marked
