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 Phylloscopus proregulus (Pallas) and P. 
coronatus (Temm.) have likewise been shot on the island. 
Iduna salicaria, Pall. (Ibis, 1862, p. 66), or Lusciola ca¬ 
lk gat a of Cordeaux (Ibis, 1875, p. 179). Blasius is correct 
in his identification, as the following particulars respecting 
this specimen will prove :— Hypolais caligata (Licht.) £ > 
28th Sept., 1851. Wing 235, tail 1*8, culmen *53, bastard 
primary *68. Second primary between the fifth and sixth. 
Two outside and two centre tail-feathers about T shorter 
than the longest. 
The second specimen mentioned by Mr. Cordeaux ( loc . cit .) 
is Acrocephalus agricola (Jerdon) $ , ]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 Saxicolce appear to have been somewhat hastily ex¬ 
amined, both by Blasins and Cordeaux. Saxicola aurita 
auctorum (S. rufescens (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. 
Saxicola 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 Saocicola 
stapazina auctorum, nee Dresser, is not represented in the 
collection. The two specimens mentioned by Cordeaux are, 
no doubt, two specimens of Saxicola deserti , Rupp., 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-
