« The following article is based largely on collections 
made by Prof. C. F. Hartt, during an expedition to Brazil 
in 1867, anc others made by his associates, about 1876, 
while he was engaged upon the Geological Survey of Brazil. 
Most of the later collections were made by Mr. Richard 
Rathbun Some were made by Mr. J.C. Branner... Ihave 
also been able to add descriptions and figures of the spicu- 
les of some long known but poorly described species, pre- 
pared from the type specimens in European museums by 
Prof. Albert Kôlliker and sent to me by himin 1867.—Hi- 
therto the Alcyonarian fauna of Brazil has been very little 
studied. Although a few species were briefly described by 
Lamarck, Milne-Edwards, Ehrenberg and Gray, they are 
isolated examples. «... About 24 species and named va- 
rieties are now recorded, but a few are very superficially 
‘known. About 19 appear to be valid species. sufficiently 
described. » ( p. 374 )
