not by any trespasser in search of eggs, as he found the 
wing and other feathers of a Tit on a nest in one of the 
rifled boxes, whilst nesting-boxes made from hollowed logs 
aud placed in adjacent trees were undisturbed. 
In one of the latter was a Blue Tit’s nest with fourteen 
eggs, the largest number of this species ever found by 
Mr. Read in one nest. Every egg in this nest has since 
hatched out and the birds when last seen were fully fledged, 
filling the box with a seething, fluttering mass of feathered 
life. 
Mr. Cuartes Cuvuss sent the following descriptions of 
new forms from South America :— 
Myrmophila vavasouri, sp. nov. 
Adult male. General colour above and below dark slate- 
blue, including the head, back, inner secondaries, tail, 
breast, abdomen, sides of body, under tail-coverts, and 
under wing-coverts ; a white tuft on the shoulder of the 
wing; upper wing-coverts black tipped with white ; primary 
and secondary quills dark brown with pale edges on the 
inner webs, slate-blue on the outer webs, and narrowly

The types of both male and female are in the McConnell 
collection, and were collected on the Ituribisi River in 
February 1907. 
This speciés is allied to M. locas but differs in being 
dark slate-blue in its general coloration instead of ash-grey.
