There are eight sense organs, each containing a spherical mass of concretions. These are situated at regular inter- vals within notches at the disk-margin. The Milky Cross, fStaurophora laciniataj, is abundant along the Atlantic coast north of Cape Cod, during the summer months, and is occasionally seen along our coast in spring. The appear- ance of a milkj'-colored cross is produced by the large cruciform mouth bordered with veil-like frills containing the reproductive organs. It is from four to eight inches in diameter. There are numerous little eye spots at the base of the tentacles, upon the bell margin. The Thimble-Jelly, (Melicertum campanula). This little Arctic jellyfish resembles a large thimble of clear jellj-like substance with eight, yellow, radial canals extending from the stomach at the centre of the concave side of the thimble to the edges forming, so to speak, the spokes of a wheel. The edge of the bell is provided with numerous tentacles. It is exceedingly abundant until mid- summer, north of Cape Cod, but is found on our coast only in the spring.

The bell is transparent, somewhat flatter than a hemisphere, and when full grown it becomes about one inch in diameter. _ About eighty long, flexible tenta- cles arise from the side of the bell near ''^s- "; Jeiiytish, Go„,onenn,s .
