Genera not comprised in this review, because of imperfect know- 
ledge Piaster, Pet., Mediaster, Stps., Lepidaster and Amphiaster, Verr., 
Hymenaster, Cor ethr aster, and Zoroaster, Wyv.-Th., and Brisinga, Asbj. 
The following are the new genera and species and the most impor- 
tant identifications and Rectifications of synonymy in the first three 
families, which are discussed in this first part of Perrier’s paper : — 
Asterias rodolphi, sp. n., p. 305, allied to A. glacialis (Kermadec Isl.) ; 
jehennesii, p. 311 (Madagascar); fahricii, Ag., p. 320 (Labrador); 
borealis, p. 323 (Labrador) ; horhonica, sp. n., p. 325 (Bourbon) ; rari- 
spina, sp. n., p. 327 (Cape) ; vancouveri, sp. n., p. 328 (Vancouver’s 
Island) ; hrachiata, sp. n., p. 329 ; douglasi, sp. n., p. 333 (Labrador ?) ; 
nuda, sp. n., p. 335 (Torres Strait); capensis, sp. n., p. 337 (South Africa) 
fungifera, sp. n., p. 337 (New Holland) ; sinusoida, sp. n., p. 338 (Tas- 
mania) ; cunninghami, sp. n., p. 339 (Magelhaens Straits) ; meridionalis, 
sp. n., ibid. (Antarctic). Asterias novcehoracenis, P., is referred to A. 
arenicola, and A. lacazii reduced to a variety. The genera Margaraster , 
Uniophora, Gr., and Coscinasterias, Verr.; are not recognized as distinct 
from Asterias. • . 
' Anasterias, g. n. Dorsal skeleton rudimentary, almost undeveloped. 
A.minuta, sp. n., p. 345 (locality unknown). 
Ccdasterias australis, Verr., is referred to Stichaster, M. Tr. Also 
Stephanasterias, Verr., and Tonia, Gr. 
Calvasterias, g. n. Dorsal skeleton formed of imbricated plates, 
equally long and large, covered with a naked skin. (Analogy with 
Asterina.). C. asterinoides, sp. n., p. 348 (Torres Straits). 
Crossaster, Gr., is not generically distinct from Solaster. 
Heliaster canopus, Val., p. 362 (Juan Fernandez). 
In Acanthasfer, Gerv. {Fchinites, M. Tr.), 2 species are distinguished : 
echinites and ellisi. 
Othilia ani'^^Rhojjia, Qi\, are merged in Echinaster \ 0. spinosa,Qr., 
and.O. crassispina, Verr., = Echinaster echinophoras (Lmk.)j E. afflnis.
