Poraniomorpha versus Rhegaster.— Professor A. KE. Verrill, 
in the ‘Annals & Magazine of Natural History,’ ser. 8, 
vol. xiv. p. 17 (July 1914), states that the name LRhegaster, 
Sladen, 1883, has priority over Poraniomorpha, Danielssen & 
Koren, and should therefore be used if Poraniomorpha, Ihe- 
gaster, and Lasiaster constitute a single genus. ‘This is an 
error. The genera date as follows :— 
(1) Poraniomorpha, Danielssen & Koren, “ Fra den Norske 
Nordhavs-expedition,” Nyt. Mag. for Naturvidensk- 
aberne, vol. xxvi. 1880 (1881), p. 189. Type, P. rosea, 
monotypic. 
(2) Rhegaster, Sladen, Trans. Roy. Soc. Edinburgh, 
vol, xxxii. 1883, p. 155. Type, R. murray, Sladen, 
by designation (‘ Challenger’ Asteroidea, 1889, 
. 367). 
(3) ae ee Sladen, ‘Challenger’ Asteroidea, 1889, 
p. 371. Type, L. villosus, monotypic. 
In ‘ Asteroidea of the North Pacific,’ 1911, p. 248, I used 
Poraniomorpha in the sense advocated by Dr. Grieg, to 
include Rhegaster and Lasiaster. Iagree with Professor Verrill 
that it is better to include Porania, Poraniomorpha, and 
some of their allies in a family distinct from the Asteropide 
—namely, in the Poraniide of Perrier.
