Asteriidse from Kerguelen\ Island. 107 



Pen-ier, of the Jardin des Plantes at Paris, who very recently 

 identified many species of Asteriidae in the British-Museum 

 collection. 



Pedicellaster scaher^ sp. nov. 



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

 radii sensim attenuati, cylindracci, haud acutissimi, spinis bre- 

 vissimis singularibus, obtusis, scabrosis, modo irregulari aliquanto 

 reticulato ordiiiatis muniti, ils prope ambulacra quam cseteris 

 paulo longiorihus ; interstitia inter reticulationes nuda, pedicel- 

 larias maguas gerentia ; spinae ambulacrales in seriebus tribus, 

 graciles longitudinisque aequalis, quam dorsalibus duplo longiores ; 

 oris anguli intcrradiales spinis duabus parvis terminati ; anus fere 

 centralis ; tessella madreporiformis in angulo interradiali prope 

 marginem sita. 

 Disci diam. 9 millim. ; radiorum longit. 18, ad basim crass. Og ; 

 disci crass. 6. 



This species appears to agree very fairly with Sars's descrip- 

 tion of his genus Pedicellaster ^ except that the ambulacral 

 fuiTOws cannot be said to be " broad," and the ambulacral 

 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 spines are roughened with minute prickles, those of 

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

 at the tips ; and a row or two near the ambulacral 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. 



OthiUa spimdifera^ sp. nov. 



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

 mediocriter orassus, supeme leviter rotundatus ; radii cylin- 

 draceo- attenuati, spinas numerosas, brevissimas scabrosas irregu- 

 laritcr dispositas sed modo aliquanto retiouluto gerentes ; tamen 

 prope spinas ambulacrales, spatiuni est lineare fere nudum, iis 

 parallelum, versusque radiorum basim sensim latins, spinarum 

 minutarum quara ambulacrales longe rainorum serie unica mu- 

 nitum ; spina} ambulacrales supra quara que tcssellam quatuor, 

 transversim sitai, divergentcs, intirais 2 quam alise paulo longi- 

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

 anguli interradiales spinis duabus parvis terminati ; anus sub- 

 centralis ; tessella madreporiformis submarginalis, in radiorum 

 angulo. 



Radiorum longit. 14 mUlim.,diam. ad basim 4^ ; disci diam. 7, crass. 0.
