similar to those of the ventrolateral plates, some ten in number, 

 nnd sometimes separated fi-om the same group of the fellow plate 

 by a groove. Between the two groups of spines of each mouth- 

 plate there is a distinct space. 



I have examined five specimens of this species, all from 

 ISIisaki. Of these one is too much injured to be measured ; the 



rest are as follows : 



1) r=:22min. Pt = 32 mm. Pt:r = 1.5 



2) r = 16 „ R = 27 „ R:i = 1.7 



3) 1=14 „ ri = 22 „ rv:r=l.G 



4) r=13 „ R = 1G „ R:r=:1.2

Pahnipes rosa ecus (La3iaeck). 



Tlie occurrence of this species in Japanese waters appears to me not 

 well authenticated. It appears to have been first described by Laimarck as a 

 Aarieh^ of Astcrias rosacea, although previously figured. It is the nineteenth 

 species of Lajmaeck's Asterias and is characterised as follows ['16, p. 558] : 



" Astérie rosacée. Asterias rosacea. 



" A. complanata, submembranacea, utrinque tuberculis minimis et subhis- 

 pidis granulosa ; lobis obtusis brevissimis ; disco doi-sali nudo. 



"Encycl. pi. 99, f. 2-3. 



" 2. var. lohis simis. Mus. n''. 



" 3. var. lobis quiudenis. Mus. n°. 



" Habite Quelque voisine que soit cette astérie de la précédeute^^ 



]>ar ses rapports, elle me paraît s'en distinguer constamment par la forme 

 de ses lobes, et par le défaut d'écaillés au centre et sur les côtés de son 

 disque dorsal. Effectivement, la suiface supériem'e ou dorsale de l'astérie 

 i-osacée n'offre partout que de petits tubercules, tous semblables, qui lui 

 donnent l'aspect d'une jjeau de cliagiin.
