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.
