Poi'animiorpha versus Hhegaster. — Professor A. E. Verrill, 

 in the 'Annals & Magazine of Natural History,' ser. 8, 

 vol. xiv. p. 17 (July 1H14), states that the name Rhegaster^ 

 Sladen, 1883, has \)x\ov\{y oYtx Poran'iomorpha, Danielssen & 

 Keren, and should therefore be used if Poraniomorpha, lihe- 

 gaster, and Lasiaster constitute a single genus. This is an 

 error. The genera date as follows : — 



(1) Poraniomorpht, Danielssen & Keren, " Era den Norske 



Novdhavs-expedit'on,^^ i^vt. Mag. for Naturvidensk- 

 aberne, vol. xxvi. 1880 (1881), p. 189. Type, P. rosea, 

 nionotypic. 



(2) Rhegaster, Sladen, Trans. Roy. Sec. Edinburgh, 



vol. xxxii. 1883, p. 155. Tj^pe, R. murrayi, Sladen,

(3) Lasiaster, Sladen, ' Challenger ' Asteroidea, 1889, 



p. 371. Type, L. villosus, monotypie. 

 In ' AsteVoidea of the North Pacific,' 1911, p. 218, I used 

 Porayiiomorpha in the sense advocated by Dr. Grrieg, to 

 include Rhegaster and Lasiaster. I agree with Professor Verrill 

 that it is better to include Porania, Poraniomorpha, and 

 some of their allies in a family distinct from the Asteropidee 

 — namely, in the Poraniidse of Perrier.
