162 Mr. H. Seebohm on the Ornithology of Heligoland. 



twenty specimens of Phylloscopus superciliosus (Gm.) which 

 have been shot on the island. It will also contain irre- 

 futable evidence that Phylloscojjus proregulus (Pallas) and P. 

 coronatus (Temm.) have likewise been shot on the island. 



Iduna salicaria, Pall. (Ibis, 1862, p. 66), or Lusciola ca- 

 ligata of Cordeaux (Ibis, 1875, p. 179). Blasius is correct 

 in his identification, as the following particulars respecting 

 this specimen will prove-: — Hypolais caligata (Licht.) S> 

 28th Sept., 1851. Wing 2-35, tail 1*8, culmen -53, bastard 

 primary '68. Second primary between the fifth and sixth. 

 Two outside and two centre tail-feathers about "1 shorter 

 than the longest. 



The second specimen mentioned by Mr. Cordeaux [loc. cit.) 

 is Acrocephalus agricola ( Jerdon) ? , 1 2th Jan., 1864. Wing 

 2"05, tail 2, culmen "5, bastard primary "4 (very small and . 

 pointed, scarcely projecting beyond the outer wing-coverts) . 

 Second primary equal to the sixth. Centre tail-feathers 

 longest, the two outside ones being '35 shorter. 



The Saxicol(B appear to have been somewhat hastily ex- 

 amined, both by Blasius and Cordeaux. Saxicola aur'ita 

 auctorum {8. nifescens (Briss.) of Blasius in Ibis, 1862, 

 p. 70, and S. albicollis (Vieill.) of Cordeaux in Ibis, 1875, 

 p. 179) is represented by a male in breeding-plumage, shot 

 12th May 1860, and a male in autumn plumage, shot 26th 

 Oct. 1851. 



Saancola stapazina, Linn., of Blasius, in Ibis, 1862, p. 70, 

 and Saxicola stapazina, Linnaeus, of Cordeaux, in Ibis, 1875, 

 p. 179, by which both writers, no doubt, meant Saxicola 

 stapazina auctorum, nee Dresser, is not represented in the 

 collection. The two specimens mentioned by Cordeaux are, 

 no doubt, two specimens of Saxicola deserti, Riipp., a male 

 with black throat, in autumn plumage, shot 26th Oct. 1856, 

 and a female without the black throat, also in autumn plu- 

 mage, shot 4th Oct. 1855. In both these specimens the 

 axillaries are white, with concealed dusky bases, and the black 

 at the end of the tail extends for nearly an inch and a half. 



Saxicola leucomela (Pallas) of Cordeaux, Ibis, 1875, p. 179, 

 is a fine male, in full breeding-plumage, of Saxicola mo-
