REPORT ON THE ALCYONARIA. 287 



Callistephanus, n. gen. 



The only known species of this genus (Callistephanus koreni) was dredged off the 

 IsLind of Ascension. 



Stenogorgia, Verrill. 



Of the two species, one, Stenogorgia casta, Verr., was taken in the Atlantic, off tlie 

 coast of Florida ; the other, Stenogorgia rosea, Grieg, at Haakonsund, Korsfjord. 



Loph ogorgia, Milne -Edwards. 



All the known species come from the south and east coasts of Africa, extending from 

 the Cape of Good Hope district northwards to Delagoa Bay, and as far south as Prince 

 Edward Island. 



Leptogorgia, Milne-Edwards, emend. Verrill. 



The very numerous species of this genus, as understood by us, have a somewhat 

 peculiar distribution, commencing with a series of forms like Leptogorgia viminalis {J^aW.) 

 and Leptogorgia sarmentosa (Esp.), which are found in the Mediterranean, the latter 

 extending its area to the Azores ; the former and Leptogorgia wehbioMa (Val.), are found 

 at the Canary Islands ; Leptogorgia pinnata (Liu.), is found at the Gaboon. On the 

 western side of the Atlantic, Lejytogorgia teres, Verr., has been taken in the Bay of New 

 York, Lep>togorgia Jioridana, Verr., at Florida, Leptogorgia miniata, Verr., at the 

 Antilles, Leptogorgia purpurea (Pall.) at Brazil, Rio .Janeiro, and extending around the 

 coast of South America as far into the Pacific Ocean as Chili ; Leptogorgia arhuscula 

 (Phill.) is found both in Patagonia and Chili, while numerous species, Leptogorgia 

 Jlexilis, Verr., Leptogorgia rigida, Verr., Leptogorgia diffusa, Verr., &c., are found at 

 Panama; Leptogorgia cuspidata, Verr., Leptogorgia pjerimna, Verr., Leptogorgia ramulus, 

 (Val.), Leptogorgia adamsii, Verr., are recorded from Peru ; Leptogorgia californica, 

 Verr., Leptogorgia stenohrachis (Val.), are from California. A few species are found in 

 Australasia, Leptogorgia arenata (Val.) at New Zealand, and Leptogorgia. torresia and 

 L. a-ustraliensis. Rid., at Australia. 



The general line of the distribution would appear to be along the shores of Africa as 

 far as the Equator ; along both the coast lines of America from the 30th degree of 

 latitude, with an outlier in the Pacific Ocean. 



Gorgonia, Auct. emend. Verrill. 

 All the species of this genus, as now limited, are found in the Atlantic, some in tlie
