Upon consideration of all the features and evidences pre- 
sented in my research I do not hesitate to say, that I believe 
the larvae which construct these and similar nests, are the 
cidse, perhaps the Bombyx Humboldt has mentioned as 
being found in Mexico. 
There is another specimen of a nest upon which Mr. 
Spence has written a ticket, “inner layer of a nest of Grega- 
rious Caterpillars, species not known.” As there is no such 
lining to be found in the three nests just described, I con- 
clude it must have been obtained from a different kind of 
nest, though it is quite probable the nest was one made by 
a gregarious moth ; it is fourteen inches long, eight inches 
circumference in the middle, tapering sharply at each end, 
it has been pendant like the others. The material is a thin 
sort of skin of brown colour, wonderfully like some of the 
common Japanese-made papers. There is no doubt of its 
having been stripped without difficulty from the inside of a 
stiff pendant nest, as it was held to the sides only by silken 
web. This nest when complete and hanging from the bough, 
would look like a long and somewhat elegant flask.

Mr. M. M. Hartog, B.Sc., F.L.S., exhibited a Seiss’ earner

He also exhibited some slides illustrating the segments 
organs of the Leech.
