This species has never been taken in our waters but once, so far as I know. The two original specimens were much alike. It has not j'et been figured, and therefore I have illustrated it here (fig. 3). It seemed to be distinct from the common European species, A. digitatum, to which it is nearly allied. It grows in'the form of flattened lobes or fronds, covered to the base with spaced slightly raised calicles, and with a finely granulose coenenchyma between the calicles, which is filled with small white simple warted spicules, mostly acute spindles. Off Cape Cod, on the Fishing Bank, in 80 fathoms. It was found where the the bottom is rocky, and probably it occurs on all the more northern fishing banks off Nova Scotia on i-ough rocky bottoms, where it is hard to use suitable apparatus for collecting adherent species. The type is in the National Fig. 3. Alcyonium snUreum Vet. sp. nov. Type. Drawn while living, x Ij. Family NEPHTHYID.^ Verrill, 1865. NephtJiyidce, Verrill, Proc.

This species, contracted in alcohol, has various forms, much like those of G. rubiformis. The specimens are attached to dead shells and stones by a thin expanded base, which appears finelj- granulose under a lens, especially when.
