ACTINOPODOUS HOLOTHrPJOIDEA. 95 



isfc das untorsuchte Material zu geringfiigig, um init Entsehicden- 

 hcit eine solclio Aufeinauderfolgo der Kalkkdrpcr in dor Entwick- 

 lung dos Individuums behaupten zu konncn ; doch maclit die 

 siclier constaticrte Bcobachtung Baur's von dcm analogcn Vorgange 

 bei Synapta digitata eine solche Deutung der oben angegebenen 

 Thatsachen jedenfalls sehr wahrscheinlich" (Semper 18G7 — 8, p. 92). 



Also LuDWiG says of //. lubrica (1887rt, p. 4) : — "Bei dem 

 kleinsten, nuv 1.5 cm. langen Exemplai-e findon sieh aber aussor- 

 dem in der Nabe der Endseheibchon der Fiisschen audi nocli 

 durchlocherto Kalkgebilde, welclie zwar kleincn Aufsatz liaben, 

 sonst aber an die von Semper bei seiner 77. erinaceus var. pygmara 

 bcschriebenon und abgobildeten Kalkkorper erinneron." Here it 

 is evident that Ludwig too observed the presence of tables or at 

 least of their disks in the young of 77. lubrica. 



I think there is hardly any question that the specimens I 

 have examined belong to 77. moehii Ludwig. At any rate, I do 

 not feel justified in establishing a now species, as there is no sub- 

 stantial ground to build it on. There can also be no doubt that 

 it is closely allied to 77. lubrica and other related species as was 

 pointed out by Theel. The only point of difference besides 

 that in the arrangement of stone canals, is the fact that there are 

 H-shaped supporting rods in H. moebii. But even these may some- 

 times be absent as in tlie specimens froni Koshiki (.No. 1257). 

 It may be supposed that these six;cimons do not belong to 77, 

 moehii but to some other species. But a careful dissection shows 

 that they are exactly like the other specimens of 77. moehii, so 

 that I do not feel justified in specifically separating it from them. 

 At the same time, the absence of H-shaped bodies and the shape 

 of the rods make them identical with 77. glaberrima Selenka or 

 H. marenselleri Ludwig,
