The Aleyonarians collected by Mr W. S. Bruce on the Scotia voyage represent nine species—six of which are new, namely:—

Primnoisis ramosa, n. sp.

Thonarella brucci, n. sp.

Amphilaphis regularis, Wright and Studer.

Primnoella scotiæ, n. sp.

Primnoella magellanica, Studer.

Paramuricea robusta, n. sp.

Gorgonia wrighti, n. sp.

Gorgonia studeri, n. sp.

Umbellula durissima, Kölliker.

Apart from the six new species, the collection is of interest in extending our knowledge of the geographical distribution of previously recorded forms. Thus Amphilaphis regularis, Wright and Studer, previously collected off Inaccessible Island, Tristan da Cunha, and off Nightingale Island, was got in abundance off St Helena; Primnoella magellanica, Studer, previously collected off Monte Video and in the Magellan Straits, was obtained at Burdwood Bank 54° 25′ S., 57° 32′ W.; while Umbellula durissima, Wright and Studer, previously obtained by the Challenger from the North Pacific Ocean, south of Yeddo, was found by the Scotia at 48° 06′ S., 10° 5′ W.
