white variety frequents white flowers; and the spider is thus less ap- 
parent to the insects on which it feeds when they are stupified with 
the juice of the flowers. Pholcus phalangioides also seems to have 
been recently introduced, and the only specimen observed was in an 
apartment.

Curtous Worms within the Peritoneal Sac of a Redthroated Diver shot at Flam- 
borough.—l received a few days ago, in the flesh, a specimen of the redthroated diver 
which had been shot off Flamborough, by Thomas Leng, of that place. It was in the 
summer or breeding plumage, and I believe of the second year, for the shades of 
colouring are not so peffect as in a fully mature specimen, and the red on the throat 
is of more than usually circumscribed dimensions. This imperfection of colouring 
may, however, have been due to other causes than that of immaturity. On opening 
the body to ascertain the sex, I was astonished to find within the peritoneal cavity or 
sac numbers of small white worms, varying in length from a quarter of an inch to 
nearly an inch. These worms appeared in the greatest numbers within the folds of 
the mesentery, although they were scattered here and there throughout the whole 
peritoneal sac, and were consequently external to the bowel. Their locality appears 
to me very strange, for althongh Entozoa dwell in and feed upon most of our own 
organs and their cavities, as well as those of the lower animals,—of which the “ fluke” 
in the liver (especially of the sheep), the “ bydatid” in the liver and brain, &c.,.and
