occurs in the medusa of Sarsia prolifera, the only example known 
of budding in free medusæ. Alex. Agassiz has shown that bud- 
ding occurs in the free medusa of Lzzzia grata, also in Dysmor- 
Phosa fulgurans and in Hybocodon prolifer. These medusz are 
all found in New England waters. Many similar cases have been 
described in Mediterranean genera.” 
By an odd chance I had under the microscope, at the time I 
read this article, a medusa, a Willia, which must be added to this 
list, as it produces medusa by budding from the base of the manu- 
brium. During the latter part of July I took with the dipping 
net, in Beaufort Inlet, N. C., a great number of specimens of 
Willia ornata (McCr.) at various stages of growth; they agreed 
perfectly with Mr. Alex. Agassiz’s description and figures, and 
show that the latter author was correct in referring two specimens 
to the same species as the single specimen found by McCrady at 
Charleston. With them was a single specimen of another form, 
which at first appeared to belong to a second species of Willia. 
Although it was larger than those of the ccmmon form in which 
the reproductive organs were fully developed, these were entirely 
wanting ; there was a slight difference in the outline of the bell; 
the tentacles were only eight in number, short and thick, and 
usually carried coiled up under the edge of the bell. The tubes 
with the clusters of lasso cells, contained only a single cluster 
each, instead of two or three clusters, as in the ordinary form. 
On the inner surface of the bell, where the radiating chymifer- 
ous tubes joined the manubrium, and therefore nearly in the posi- 
tion which is usually occupied by the four reproductive organs, 
four long branchial stolons hung down into the cavity of the bell, 
and the tip of each branch terminated in a medusa bud, with 
four rudimentary tentacles. 
budding, so that we have an alternation of generations of free 
medusæ. 
The specimen soon died in conānement, and as stormy weather 
set in that night I got no more of them, hence the question 
whether the two forms belong to the same species must therefore 
be left in doubt for the present—W. K. Brooks, Beaufort, N. C. 
_ ENGLISH Sparrows REFUSING ro EAT Worms.—One can hardly 
blame either bird or beast for not liking to eat caterpillars and 
canker-worms, but when it is claimed that that is what the 
English sparrow is for, it is well to keep the facts of the case be- 
fore the people, as a great many persons are doing. I observ 
a “sin of omission ” on their part here in Washington, which 
I do not remember to have seen in print. After every rain the
