Dec. 18,1894.—Exhibits:—Mr. Hanbury: a specimen of Choerocampa 
celerio, found by a gardener in a potting-shed at Hassock’s Gate, Sussex, 
on Nov. 7tli, 1894; the specimen was perfect, except that it was some¬ 
what rubbed by its captor. Mr. Tutt remarked that most of the rare 
Hawk-moths captured in this country had been introduced with foreign 
plants, as they were not known to breed regularly in this country. Mr. 
Hanbury also showed a fine example of Crocallis elinguaria , having the 
central spot very large and dark, and the usual tranverse lines almost 
obsolete and brighter than the ground-colour, which was of the normal 
tint; the insect was bred from a batch of Sutherlandshire eggs. Mr. 
Prout: continental types of Caradrina alsines, C. ambigua and C. 
superstes. The Rev. C. R. N. Burrows : Cerastis vaccinii vars. variegata , 
Tutt, mixta, Stgr. and suffusa, Tutt; also C. ligula, and vars. subnigra , 
Haw. and spadicea, Haw.; all from Rainham. Mr. Battley also ex¬ 
hibited these species from Winch more Hill and Dorset. Mr. Riches: 
a specimen of Caradrina cubicularis taken about the middle of last 
month while drying its wings. Mr. Sauze : an example of “ Symbiosis ” 
(or the “ living together ” of two or more animals of totally different 
orders, families, or species) represented by Pinnotheres pisum (the Pea 
Crab) and Mytilus edulis (the common mussel), the former amicably 
sharing the latter’s shell with its rightful owner. He read notes on 
the subject giving other instances of this curious habit. Mr. Tutt: 
Colias phicomone and C. palaeno from Mont de la Saxe and the Cogne 
Yallev.

Jan. lsi, 1895.—Exhibits :—Mr. Prout: Agrotis cursoria from Aber¬ 
deen and St. Anne’s-on-Sea, the former being considerably darker than 
the latter. Capt. Thompson : Vanessa urticae, Epinephele ianira and 
Lycaena icarus, all from Sligo. The V. urticae were somewhat rougher- 
looking than the English form; the E. ianira paler, and more clearly 
barred on the underside; one of the L. icarus had a series of pale blue 
crescents on the inner edge of the orange spots on the hind-wings. 
Mr. Clark : Scoparia cembrae and vars. 
Jan. \6th, 1895.—Exhibits:—Mr. Oldham: Eupithecia subfulvata from 
Epping Forrest, Polia chi from N. Wales, and dark Cidaria russata from 
Wisbech. Mr. Southey : varieties of Arctia caia; one having much 
brown on the fore-wings and yellow hind-wings, and two having the 
fore-wings almost entirely brown. Mr. Bacot: a young alligator from 
the Mississippi, which had lately died in captivity; it was about a foot 
long. He asked whether anyone could tell him if what he had heard 
was true, namely, that alligators in captivity will only grow to a certain 
size if kept in a small pond, but if removed to a larger one they proceed 
to grow again up to a limit and then stop again, repeating the process 
if repeatedly removed to larger ponds, presumably, till full-grown. Mr. 
Clark drew attention to the flap-arrangement in the mouth of the 
specimen exhibited, which could, at the will of the reptile, be shut over 
the entrance to the throat, thus effectually preventing the ingress of 
water when the creature had a large animal in its jaws. Mr. May: 
Xylophasia monoglypha from Tooting Bee Common, two of them taken 
last year being somewhat unusually dark; he also showed a moderately 
dark Scotch specimen for comparison.
