1. 3-Acetyl-2,7-dihydroxy-6-methylnaphthazarin, not previously described, has been isolated from the test and needles of the sea urchinStronglyocentrotus nudus.

2. The pigments of this sea urchin have been shown to include 2,7-dihydroxynaphthazarin and spinochrome E.

3. A number of minor pigments forming naphthazarin derivatives has been isolated. One of them is connected with spinochrome C by mutual transformations.
