St. Lucas ; L. arenata, V. {Rhijndogorgia arenata^ Val., Edw. & H.), New Zea- 
land. The following species, which Dr. Kolliker refers to his first section of 
the genus Gorgonia, probably belong to Lcptogorgia^ as modified ; but I have 
not examined them : — G. mnhclla^ Esp. (Rhipidogorgia, E. & II.) ; G. venusta^ 
Dana (Rhipidogorgia, E. & II.) ; G. ventalina, Linn. (Rhipidogorgia, E. & H.) ; 
G. caidiculus, K. (Gorgonella, Val., Leptogorgia, E. & H.l G. sanguinolenta, 
Esp. (non Pallas), K611. leones, Taf. xviii. fig. 239 (? G. peicchizans, Pallas). 
Two species described by Duchassaing and Michelotti, L. Jlavida and Gor- 
gonia ohlita, are probably additional species.

Beefs, Brazil ; G. sanguinea, Lam. (Leptogorgia sanguinea (pars), E. & H.), 
locality unknown. 
E. Dichotomous, often fasciculate; the branches ascending, with the 
coenenchyma developed laterally into marginal wings, thus produ- 
cing flat or triquetral branches, with the cells in rows along the edges.

laterally developed into broad, frond-like forms, (Hymenoyorgia.)
