There may be doubt whether P. pacifica is not a variety of P. arborea. This can hardly be determined until more specimens come to hand. Careful study of the spicules in this group is necessary for the determination of Fig. 1. Paragorgia arborea (Linn.). Swollen end of a branch, with ployps and numerous siphonozooida, partly expanded. From Atlantic Fishing Banks. x2. Paragorgia arborea (Text fig. 1) is very common on the deeper fishing banks off Nova Scotia and Newfoundland, where it grows to a great size. Some of the specimens from there have been 4 to 5 feet high, with the main trunk 4 inches in diameter at the base. Specimens two or three feet high are not un- common. It branches irregularly, often in truly arborescent forms, but in other cases the branches are irregular and sometimes reunite in various ways. They, often have nodes or bunches, and very often the tips of the branches arc swollen or bilobed (see fig. 1). It has numerous siphonozooids. »Proc. Zool. Soc. London, p. 548, 'Proc. Nat.
