A portion of a colony of this species in excellent preservation is in the collection ; the 

 bottle in which it was stored had lost its label, but in it there was also a frasfment of 

 Leptogorgia lutkeni from Prince Edward Island, and as the original specimen of Gorgonia 

 Jlammea, E. and S., came from the Cape of Good Hope, it seems not unreasonable to assume 

 that the present specimen was taken cither in Simon's Bay or in the dredgings off Prince 

 Edward Island. 



Genus leptogorgia, Verrill {emend?}. 

 Leptogorgia, Milae-Edwards, Hist. Nat. des Coralliaires, t. i. p. 163. 



VerrilP emends this genus so as to make it include " all those Gorgonids having a horny 

 axis, thin coenenchyma, finely granulous at the surface, and composed of very small warty 

 spicules in the form of longer and shorter double spindles, usually mingled with more or 

 less numerous small heads and double heads, the polyp spicules long and slender, simple, 

 with few warts. The cells are usually arranged in lateral rows or bands, and may be 

 either flat or more or less elevated on verrucse." 



As so constituted, this genus embraces a very well marked group, but excluding 

 Lophogorgia ; most of the species are shallow-water forms. 



Leptogorgia purpurea (Pallas) (PI. XXIX. fig. 1; PI. XXXIV. fig. 3).

There are two specimens of this species in the collection taken off" Bahia, the smaller 

 is that figured ; another specimen was dredged off" the coast at Chili, and in considerably 

 greater depths. This species is recorded by Milne-Edwards from Brazil, and Ijy Verrill 

 from Rio Janeiro. It is not without interest to find it extending its geographical area 

 round South America, as far as Chili. Except in a slight diff"erence in the shade of red 

 colour the specimens are alike. The spicules of the coenenchyma are chiefly oblong 

 spindles with from two to four zones of wart-like prominences; these measure 0'12-0'04 ; 

 0"08-0'03; 0'06-0'03 mm., and broader spindles almost oval in outline measuring 

 OOS-O'OG ; 0"0G-OO4 mm. In the polyps the spicules are flat, irregular in outline,
