undisturbed and forgotten for two years, when happening to see 
the box, to his great surprise upon opening it, the Lepisnia was 
found as lively as if only just put in, and apparently none the 
worse for its two years solitary confinement without food and light, 
and with very little air. One would like to know the length of 
life of these insects. 
Furtueii Note on the Spongeous Origin of Flints. 
By F. Kitton. 
(See 1871—72, p. 59.) 
In my paper on the above subject (published in the Transactions 
for 1871 — 72) I gave a figure (page 59, fig. 2) of the microscopic 
structure of a sponge-like organism from the greensand, Carrow, 
Norwich. Since its publication I forwarded specimens to II. J. 
Carter, Esq., F.R.S., and he pronounces it to be a new species 
of sponge, belonging to the Lithistida3, and has described and 
named it as follows, Lithospougitis kittonii. — Carter. “Fossil 
species in which the surface spicule is not known, but in which 
the body spicule has a branched fdigreed form, Carrow Hamlet, 
Norwich.” — “Annals and Magazine of Natural History,” vol. xii. 
Through the kindness of ilr. Carter I have been enabled to 
compare it with a recent form (Corallistes borealis — Carter) in 
which the siliceous skeleton (body spicules) has a similar tubercled 
appearance as Lithospongitis kittonii.

Sea Eagle {Haliccetus abicilla.) A fine young male was shot 
at Stokesby, near Yarmouth, on the 22nd of April, having fre- 
quented the neighbourhood for some days. 
"White-winged Black Tern {Sterna leucoptera.) Of this 
species, until lately one of the rarest terns in the British List, five 
specimens were killed out of a flock of seven, at Hickling, near 
Yarmouth, on the 30th of May, and several more were said to 
have been seen.
