Note 7 — EAST COAST OF ENGLAND.

It is worthy of note that on the same day a fine example of Papilio podalirius, the scarce Swallow-tail, was taken on the island. This butterfly was added to the British list on the authority of Haworth, but no authenticated British specimen is known: its occurrence on Heligoland adds to the probability of its capture in England, [Saxicola deserti also occurred at Alloa, in Scotland, on Nov. 28th, 1880.—J.A.H.B.]
