Asteriidee from KergneJcii' s Island. 107 



PeiTier, of the Jardiii des PlaiitCvS at Paris, who very recently 

 identified many species of Asteriidaj in the British-Museum 

 collection. 



Pedicellaster scaher^ sp. nov. 

 Discus 5-radiatus, latitudine circiter radii longitudinis | sequaus; 

 radii sensim attenuati, cylindracei, baud acutissimi, spinis bre- 

 vissimis singularibus, obtusis, scabrosis, modo irregulari aliquanto 

 reticulato ordinatis muniti, iis prope ambulacra quam ca3teris 

 paulo lougioribus ; interstitia inter reticulationes uuda, pedicel- 

 larias maguas gerentia ; spinse ambulacrales in seriebus tribus, 

 graciles longitudinisque aequalis, quam dorsalibus duplo longiores ; 

 oris anguli iuterradiales spinis diiabus parvis terminati ; anus fere 

 centralis ; tessella madreporiformis in angulo interradiali prope 

 marginem sita. 

 Disci diam. 9 millim. ; radiorum longit. 1 S, ad basim crass. 5| ; 

 disci crass. 6. 



This species appears to agree very fairly with Sars's descri])- 

 tion of his genus Pedicellaster.^ except that the ambulacral 

 furrows cannot be said to be " broad/' and the ambnlacral 

 spines are not in two rows but three. But these are more 

 specific than generic characters ; and therefore 1 think this 

 may safely be regarded as a second species of that northern 

 form. 



The s])ines are roughened with minute prickles, those of 

 the dorsal surface being about twice as long as tliiek, and blunt 

 at the tips ; and a row or two near the ambnlacral spines are 

 rather longer, and the latter are still more elongated. The 

 spines on the back of the disk and arms do not display any 

 regular arrangement, but are disposed in an irregularly and 

 rather closely reticulating manner. 



Othilia spmulifpra^ sp. nov. 



Discus 5-radiatus, latitudine circiter radii longitudinis | fcquans, 

 mediocriter crassus, superne leviter rotundatus : radii cylin- 

 draceo- attenuati, spinas numerosas, brevissimas scabrosas irregu- 

 lariter dispositas sed modo aliquanto reticulato gerentes ; taraon 

 prope spinas ambulacrales, spatium est lineare fere nudum, iis 

 parallelum, versnsque radiorum basim sensim latins, si^inarum 

 minutarum quam ambulacrales longe miuorum serie uuica mu- 

 nitum ; spinas ambulacrales supra quamque tessellam quatuor, 

 transversim sitfe, divcrgentes, intimis 2 quam alice paulo longi- 

 oribus, et ad intimse basim spina gracillima parva sita est; oris 

 anguli iuterradiales spinis dnabus parvis terminati ; anus sub- 

 centralis ; tessella madreporiformis submarginalis, in radiorum 

 angulo. 



Radiorum longit. 14 millim., diam. ad basim A^ ; disci diam. 7, crass. (!. 



This curious little species does not displav any particular
