“‘ Entomologists’ Record,” Mr. Muschamp, of Staefa, had named 
some very small specimens of this species as ab. minima. In 
the November number of the same magazine M. Lambillion, 
of Namur, wrote, saying that he had named this aberration 
in 1902 as ab. napella, and about the same time the Baron 
Crombrugghe, of Brussels, had called it ab. minor. While he 
(Mr. Turner) was afraid it was quite impossible to prevent 
the naming of aberrations, races, etc., still it was quite 
possible in his opinion to regulate it. He looked forward to 
the future power, influence and authority of the International 
Congress of Entomology, and threw out the suggestion that 
there should be a permanent international committee chosen 
by the Congress who should consider each new name proposed, 
and that no name should be considered valid until it had 
received the sanction of that committee. If only all the 
chief magazines and all the principal systematists would 
support this committee and recognize only the names re- 
commended by them, the multiple naming, which often occurs 
from mere ignorance, would practically disappear. 
Dr. CHapman remarked that local races required special 
names if any forms did so, and that he had already remarked 
upon the Scotch form of Z. aethiops, though without naming 
it, and had observed that this small form had the genitalia 
proportionately small, which was very far from being universal 
in small local races. 
A long and important discussion took place on the subject 
of varietal, and especially aberrational, names, in which the 
PresipENT, Prof. Poutton, Dr. Jorpan, and Messrs. GAHAN 
and WHEELER took part; Prof. Poutton remarking that 
the subject was one on which a discussion might well take 
place after previous notice, as it was really too important to 
be dealt with offhand. 
ConTRASTS IN COLOURING BETWEEN CERTAIN SPECIES oF But- 
TERFLIES FROM THE LAGos DISTRICT AND THEIR GEOGRAPHICAL 
Races at Enrespe.—Prof. Poutton exhibited a series of 
specimens bearing upon the view, again recently advanced, 
that changes of colour and pattern in allied forms are due to 
climate, and especially to moisture. The western specimens 
were all collected or bred by Mr. W. A. Lamborn, just above 
sea-level, in the Lagos district. The Uganda specimens were
