Var. y. —Larger than either of the preceding, and having a black spot on the 
upper -wings, the tips and some triangular patches being of the same 
colour; the hinder wings rather pale, with the three first nervures, alone, 
dilated and greenish. Considered by Esper, Stephens, and others a dis¬ 
tinct species, and called by them P. napcece. 
The caterpillar feeds principally on Cabbages, and is of a dull green 
colour, lighter on the sides, with yellow stigmata, covered with white 
warts, which are dusky at the tip, and give rise to short tufts of hair.

ORNITHOLOGICAL NOTES. 
By Beverley R. Morris. 
It is a circumstance worthy of notice, that there were no Terns (Sternce) 
among the Gulls whose visit to the coast of Dorsetshire I recorded in the last 
number. I did not see one the whole time the Gulls remained, but as soon as 
these latter left us, the Terns made their appearance in considerable numbers. 
Does this arise from any difference in their food ? or from the Gulls beating them 
away ? I am inclined to believe that the latter may be the cause. 
It is also a curious fact, that birds so readily remark any deviation from the 
general appearance of their family. This I noticed in the case of a Gull with 
vfhat appeared to me to be a very long tail, which was attacked on all sides by 
the other Gulls, whether of the same species as itself or not, I cannot say. On 
its coming tolerably near to me, I discovered that it had a piece of ribbon or rag 
attached to its tail. This at once accounted for its being hunted in the way it 
was. It was not close enough to enable me to be sure of its species, but I think 
it was the Common Gull fLarus comus). I suppose some one had caught it 
previously, and wished to set his mark on it. About three years ago—I think 
in 1834—I also remarked a similar fact with respect to a Chimney Swallow 
(Hirundo rustica), with a long piece of twine attached to its foot; the poor bird 
seemed to be the sport of all the Swallows in the neighbourhood, and as they 
were then congregating preparatory'to migration, it had plenty of enemies. I 
observed it for two or three days, but what then became of it I had no oppor¬ 
tunity of ascertaining. 
I may also as well here mention one or two curious instances of nest building.
