in this country, and Mr. Rothschild has stated (Avifauna of 
Laysan, p. 97) that Lafresnaye’s type is in the Paris Museum, On 
this point he must have been misinformed, and the specimen he 
* carefully examined ” there was probably one of the pair obtained 
and presented by Néboux (Revue Zoologique, 1840, p. 289), from 
which presumably the figures in the Voyage of the ‘ Vénus’ (Ois. 
pl. i. figs. 1, 2) were taken. It is almost needless to remark that 
had the present example been attainable by Mr. Wilson he would 
never have supposed it to be specifically identical with the bird 
which he found in Hawaii; and I may observe that not one of the 
five examples of the Hemignathus lucidus of Oahu at his disposal— 
two from Berlin, two at Cambridge, and one in the British 
Museum—was that of a male in full plumage. 
Mr. W. B. Tegetmeier, F.Z.S., exhibited an interesting 
application of the Réntgen rays to ornithology, in the shape of an 
actinograph taken from a Partridge that had “ towered ” on being 
shot. The actinograph seemed to show that the “ towering ” was 
caused by injury done to the lungs, and not by lesion of the brain, 
as often supposed.

Between July 29th and August 8th of this year I enjoyed the 
great advantage of a berth on H.M.S. ‘ Research,’ by the per- 
mission of the Lords Commissioners of the Admiralty, extended to 
me at the request of the Council of the Royal Society. I am glad 
of this opportunity to tender my thanks, not only to both of these 
bodies, but also to Capt. Mcore and the other officers of the 
‘Research’ for placing at my disposal every facility that lay in 
their power. 
My chief object on the cruise was an attempt to ascertain 
whether the intermediate zones of water between (say) 100 and 
700 fathoms are characterized by definite forms of planktonic life 
or not; and if so, what temperature-limits form barriers to the 
distribution of various species. The large number both of surface 
and deep-water organisms obtained during the cruise will demand 
so long a study that it seems best to publish results as soon as 
obtained in the scant leisure of which a teaching post admits. 
The present note forms, therefore, the first of a series, in which
