1877.]| MR. R. COLLETT ON PHYLLOSCOPUS BOREALIS. 43 
Dr. Giinther read a memoir on the Tortoises collected by Com- 
mander Cookson, R.N., during the recent visit of H.M.S. ‘ Peterel’ 
to the Galapagos Islands. 
Mr. Howard Saunders exhibited a specimen of the Panay Sooty 
Tern (Sterna anestheta'), which had been obtained on the British 
coast on a light-ship, probably either at the mouth of the Thames 
or of the Medway. 
This was stated to be the first notice of the occurrence of this 
bird within British limits. 
Mr. Sclater called attention to the original and unique specimen 
of his Manucodia comrii (P. Z. 8. 1876, p. 459), now belonging to 
the collection of the Marquess of Tweeddale, the President of the 
Society, which, since it was described and figured, had undergone a 
most efficient ‘‘ remake” in Mr. Bartlett’s able hands. 
The curly feathers of the head, were now much more apparent 
and better developed than shown even in the woodcut given with 
the original description, and formed standing ridges over each eye. 
The tail was not flat, as would appear from the figure (pl. xlii.), but 
“‘ boat-shaped”’ as in some of the American Grakles (Quiscalus), 
i. e. with the median tail-feathers elevated above the lateral. The 
two middle tail-feathers were very peculiar in construction, being 
shorter by 7 of an inch than the next pair, and having the inner 
webs twisted round over the outer, so as to show their under 
surfaces. 

The following papers were read :—

In the summer of 1876, when visiting for the third time during 
the last six years the province of Finmark, mainly with the object of 
studying fishes and marine invertebrata, I resolved on devoting a few 
days to excursions along the forest-clad slopes of the rivers that flow 
into the great Porsanger, Laxe, Tana, and Varanger fjords. Among 
the more southern of the vertebrate species occurring here in con- 
siderable numbers, I hoped to light upon forms not hitherto observed 
in those regions (the most northerly of our country), and further 
elucidate the question as to what influence their occurrence in dif- 
ferent degrees of latitude exerts on their outward structure and 
general habits. These parts of.Finmark having never before been 
visited by any naturalist, it struck me as not impossible that I might
