172 TlMEHRl, 
Quite recently, however, through the kindness of Mr. 
Arthur Waby of the Botanical Department, who pro- 
cured me the specimen, I have been able to identify the 
common " Who-are-you," and it turns out to be nothing 
more nor less than the very widely distributed species, 
Nyclidromus albicollis. From the fa6l that this is the 
only species of goatsucker obtainable near the houses 
in the Gardens, where also the " Who-are-you " cries are 
heard, there can be no doubt of the relation of the cries 
to the species of bird, the more especially as the speci- 
men was secured as it issued from a thicket, in which, 
just before, the cries were being uttered. 
The species will be recognised by its ashy-grey and 
brown soft plumage, mottled with yellowish brown, 
especially on the upper part of the wings ; by its white 
patch on the throat, white bar across the wings, and 
white second and third quills in the tail.

Young Animals taking Refuge in the Mouth of their 
Parent. — For years and years, the question has been 
debated as regards snakes, whether the young of vipers 
ever take refuge in the mouth of their parent for pro-

that they do, on the other it has been as definitely 
stated that they do not, each side producing what it 
regarded as incontrovertible evidence on the point. 
The opponents in the matter had this fundamental 
fa6l in their favour, that all vipers bring forth their 
young alive, and that if pregnant, snakes be encountered 
and chopped across the hinder part, young snakes will be 
found inside, which, to the ignorant, might be a proof 
that the young snakes had been swallowed by the mother
