BIRDS OF HELIGOLAND AND OF THE BRITISH ISLANDS. 267 



circia, A. crecca, A. clypeata, Tadorna cornuta, Fuligula nigra, 

 F.fusca, F. perspicillata, F. marila, F. cristata, F. ferina, F. 

 nyroca, F. clangula, F. glacialis, Somateria mollissima, S. specta- 

 bilis, S. stelleri, Mergns merganser, M. serrator, and M . albellus, 

 — but very few of the occasional visitors to the British Islands 

 have been observed on Heligoland. We have no record of Anser 

 rujicollis, Tadorna rutila, Anas americana, A. carolinensis, A. 

 discors, Fuligula rujina, F. albeola, F. histrionica, or Mergus 

 cucullatus. Probably some of these species have visited Heligo- 

 land, but have not been recognised. 



The Tubinares are represented in both lists by Fulmarus gla- 

 cialis, Pufflnus major, P. griseus, P. anglorum, Procellaria leachi, 

 and P. pelagica, but the British list also contains Puffinus obscurus, 

 Oceanites ivilsoni, and, if single occcurrences be admitted, Daption 

 capensis, Bidiveria columbina, (Estrelataluesitata, and (E. torquata. 



The Heligoland Charadriida differ very slightly from those 

 which visit Britain, except that fewer American visitors have 

 been detected in the smaller area. Totanus macularius, Tringa 

 rufescens and Charadrius virginicus appear in both lists ; but the 

 British list contains Charadrius vociferus, Tringa bonapartii, T. 

 pectoralis, Totanus bartrami, T. solitarius, T. flavipes, Macro- 

 ramphus griseus, and Numenius borealis, none of which have been 

 known to occur in Heligoland. On the other hand, the British 

 list boasts of a visitor from Southern Europe, Vanellus gregarius, 

 but its absence in Heligoland is more than compensated for by 

 the presence of Numenius tenuirostris and Totanus stagnatilis. 

 The other species common to both lists are Hcematopus ostralegus, 

 Charadrius minor, C. hiaticula, C. cantianus, C. morincllus, C. 

 pluvialis, C. ftdvus, C. helveticus, Vanellus cristatus, Himantopus 

 avocctta, H. melanopterus, Phalaropus fulicarius, P. hyperboreus, 

 Numenius arquatus, N. phceopus, Totanus pugnax, T. hypoleucus, 

 T. ochropus, T. glareola, T. calidris, T.fuscus, T. glottis, Limosa 

 rufa, L. melanura, Tringa canutus, T. subarquata, T. alpina, T. 

 maritima, T. platyrhyncha, T. minuta, T. temmincld, T. arenaria, 

 Strepsilas interpres, Scolopax rmticola, S. major, S. gallinago, and 

 S. gallinula. 



Of the Cursoriidce, Cursorius gallicus was shot rather more 

 than half a century ago, but Glareola pratincola is not known to 

 have occurred in Heligoland. 



Of the (Edicnemidce, CEdicncnius crepitans is common to both 

 lists.
