S. & G.). Fern, brunneo-nigra; vertice et nucha brunneis, fronte, capitis lateribus et collo albo vermiculatis; dorso postico, uropygio et cauda albis ; primariis nigris, secundariis et tectricibus alarum minoribus cum subalaribus albis; tectricibus majoribus viridescente extus terminatis, speculum alare forman-tibus: subtus pectore hypochondriis et ventre summo distincte albo transfasciatis, ventre imo cum crisso albis: long, tota cire. 24*0, ala 14*0, cauda 5*3, rostri a rictu 1*7, tarsi 2*7, dig. med. cum ungue 3*2 (Descr. exempl. ex ins. Falklandicis in Mus. S. & G.). Hab. Tierra del Fuego (Forster, Darwin, Cunningham); Straits of Magellan to Chiloe (Darwin, Philippi 8r Landbeck); Patagonia (Burmeister, Hudson); Falkland Islands (Darwin, Abbott). This is one of the oldest known species of South-American Ana-tida, being alluded to by Forster and also apparently by the Abbe Molina, as well as in Pernety's 'Voyage.' The remarks of the first author led to the name given to it by Gmelin, by which it has since dorso imo et rectricibus fusco-nigris ; pedibus flavis: long. tot. cire. 24, alee 14-8, cauda 4-5, tarsi 3, dig. med. cum ungue 2-5, rostri a rictu 1-2. Hab. Straits of Magellan (King). Though the type specimen of this bird in the British Museum bears a general resemblance to a male B. magellanica, we are by no means sure that it may not ultimately prove to be merely an immature specimen of Bernicla antarctica, the size of the bill corresponding more closely with that of the last-named species. From this, however, it differs in having a black tail, and in other minor characters. The specimen is evidently immature; but not being able to assign it positively to any other species, we leave it for the present to stand as doubtful; at the same time we think it more than probable that it will eventually be found to belong to one of the above-mentioned Bernicla. |
