[C/Fe], [N/Fe], and [O/Fe] vs. [Fe/H] for Pisces II 10694 and a sample of normal galactic very metal-poor stars. The dwarfs are represented by solid squares, the stars in the lower RGB branch by solid circles, and the mixed stars by triangles. The classical galactic CEMP-no giant CS 22949-037 is added (green square). The star Pisces II 10694 is represented by a red star. The large overabundances of C, N, and O in Pisces II 10694 are very similar to those observed in CS 22949-37.
