II. Series II. Species with unplated ambulacra: 



{' ' Eschrichti group. ' ' 

 ' ' Milberti group. ' ' 

 " Tenella group. " 

 Two distichals .................................................... " Palmata group." 



Three distichals ................................................. "Savignyi group." 



In this year also Hara described Antedon macrodiscus ( Tropiometra macrodiscus) 

 from Japan, at the same time mentioning the fact that Comanthus japonica is 

 abundant at Misaki. Prof. E. von Marenzeller gave a detailed account of the 

 occurrence of comatulids in the eastern Mediterranean; and Prof. Rene' Krehler 

 described a new form, Antedon flava ( Crotalometra flava) from the dredgings of 

 the French steamer Caudan, and in addition recorded a number of species from 

 Amboina. In this last paper he records Comanthus bennetti under the name of 

 Actinometra robustipinna, being unaware that the type-specimen of the latter is 

 an endocyclic example, representing a species in the "Savignyi group" of Carpenter. 



In 1898 Prof. Ludwig Doderlein published the results of his study of a small 

 collection of comatulids from Amboina and Thursday Island; the species noted 

 by him were the following: 



Antedon elegans ............................................ Zygometra elegans. 



Antedon microdiscus ....................................... Zygometra microdiscw. 



Antedon bidens ........................................... Oligometrides adeonx. 



Antedon ludovici ........................................... Craspcdomctra acuticirra. 



Antedon imparipinna ...................................... Lamprometra protectus. 



Actinometra pectinata ...................................... Comatula pectinata. 



Actinometra Solaris ......................................... Comatula Solaris. 



Actinometra paucicirra ...................................... Comatula rotalaria. 



Actinometra belli. .. . . 1 



[Lomaster belli. 



\Comanthus annulata. 

 Actinometra parmarra 



Actinometra regalis ......................................... Comanthina sehlegelii. 



In the following year Prof. Hubert Ludwig discussed the crmoid fauna of Zan- 

 zibar, adding to the species already known from the region Antedon fagellata (Dich- 

 rometra fiagellata, var. afra), and recapitulating the previous records of. others. At 

 the same time he published a paper on the crinoids of the Magellanic region, taking 

 the opportunity to compare the arctic and the antarctic faunas. Professor Bell 

 in the same year recorded the echinoderms which had been obtained by Mr. J. Stan- 

 ley Gardiner at Rotuma and Funafuti; there was only one comatulid (ComateUa 

 maculata) among them. He also published a list of the species which were obtained 

 by Dr. Arthur Willey during his expedition to the Pacific in search of the eggs 

 of the pearly nautilus. The species mentioned in this latter paper are: 



Antedon indica ........................................... Lamprometra protectus. 



Antedon tuberculata ....................................... Stephanometra tuberculata. 



Actinometra grandicalyx .................................. Comanthus bennetti. 



\Comaster typica. 

 Actinometra typica ...................................... [omuter gracilis. 



Actinometra bennetti ...................................... Comanthus bennetti. 



Actinometra parvicirra ..................................... Comanthus parvicirra.
