03A387A9FFF2FFAF6940CBCE9B3BFB81.taxon	discussion	Remarks: The collection site on the label (“ Falkland eilanden ”) differs from that on the underside and Schlegel 1866 (“ Malouines ”). Several Latin names are cited, those on the label and underside differ; the primary name on the latter however agrees with Schlegel 1866. The notation of “ adulte ” is present only in Schlegel 1866, and is lacking on the label and underside. Gmelin is noted as the name source on the label, Buffon as the source on the underside. Only Schlegel’s handwriting appears under the base of the pedestal. Mentioned in the June 1835 exchange list between Paris and Leiden as ‘ Oie des torres Magellanicus ’. The stand is ‘ new’ (e. g. it has Temminck’s handwriting) and does not contain any original information / handwriting by Dufresne (the mounted birds from La Coquille now present in MNHN have Dufresne’s handwriting on the pedestal underside). A possible explanation is that it arrived in Leiden as an unmounted skin and was subsequently mounted there. Upland Goose Chloephaga picta leucoptera (J. F. Gmelin, 1789) [RMNH. AVES. 230418].

Several Latin names are cited; those on the label and underside differ; the name on the latter however agrees with Schlegel 1866. Phillips is noted as the name source on the label; no name source appears on the underside. Only Schlegel’s handwriting appears under the base of the pedestal. Army Captain Charles Compton Abbott was stationed at Stanley, East Falklands in 1859 – 1861 in the Falkland Islands Detachment. He collected many birds and attached printed labels to his specimens. These labels had his full name and that of his regiment printed on one side, on the other side, he noted in pen the year, collecting location and details of the bare parts. These original labels can be found in NHMUK. So, contra the underside and Schlegel 1866, Abbott did not collect while on a “ voyage ” or “ Reis ”; moreover, his name is misspelled in Schlegel 1866. This specimen was acquired via Gustav Adolph Frank, the Amsterdam-based merchant who, though he did not collect a single bird himself, exchanged and purchased birds on a large scale with the likes of the Paris Museum and John Gould, both known to possess specimens from the Falklands (in particular those collected by C. C. Abbott). However, Frank is not mentioned as the source of this specimen in Schlegel 1866. Ashy-headed Goose Chloephaga poliocephala P. L. Sclater, 1857 [RMNH. AVES. 230436].

03A387A9FFF2FFAF6940CBCE9B3BFB81.taxon	discussion	Remarks: The collection site on the underside differs from that in Schlegel 1866. Two generic and two specific names are cited, with the primary binomial on the underside agreeing with Schlegel 1866. Both the underside and Schlegel 1866 identify the specimen as female, but only the latter identifies it as an adult. The only name source mentioned is Latham on the underside. Only Schlegel’s handwriting appears un- der the base of the pedestal. The text on the underside clearly indicates the former existence of an original label on the specimen. The bird was acquired through the Amsterdam-based dealer Gustav Adolph Frank and arrived on 30 April 1860 (see Kelp Goose RMNH. AVES. 230433 as for C. C. Abbott).

03A387A9FFE2FFBC6ADEC8AB982CFA25.taxon	discussion	Remark: The collection site on the label, underside and in Schlegel 1862 d differ. The underside and Schlegel 1862 d identify the specimen as young male but lacks at the label. Only Schlegel’s handwriting appears under the base of the pedestal. This bird is discussed by van Grouw & Steinheimer (2008), as the missing bird from 4 January 1837, however, all notes have been subsequently added and no original data is available on or from the specimen. Possibly at one stage the original label was present. Darwin donated at 4 January 1837 mammals and 450 birds of HMS Beagle expedition to the Zoological Society of London (e. g. to John Gould to described them), 34 – 39 specimens that are still in existence from the Society arrived in 1839, 1841 and 1856 at the British Museum. The Society’s labels recorded donor’s name, the acquisition date and Darwin’s specimen’s numbers (e. g. C. Darwin Esq, Jan 4 1837) (Steinheimer 2004). Another notable remark we find on the underside as the specimen was reportedly purchased from Frank in 1860. The other 5 from 7 birds from HMS Beagle expedition in Naturalis arrived in 1863 (Steinheimer 2004, van Grouw & Steinheimer 2008). The largest numbers of birds from The Falklands were those that arrived in 1859 – 1863 collected by C. C. Abbott (see this paper). At 30 April 1860, a large load arrived from Abbott via Frank at Naturalis, and amongst the specimens were 3 Circus. Cinereous Harrier Circus cinereus Vieillot, 1816 [RMNH. AVES. 191476].
