with a generally greater luunber of arms wliicli arc longer and coar- 

 ser, Ü. (Vania) parvicirra another one with a suiallei- number of moi-e 

 slender arms. Nevertheless, both the »species» vary so considerably 

 that they often intrude upon each other's spheres. 



The specimens obtaiiKnl by the Bockian expedition, simw tiiat 

 within the subgenus Vaiiia there occur types of combs of both the 

 Gomaster-, Comanthm- and (of this 1 have been convinced by observa- 

 tions on Dr Mortensen's Japanese specimens of this species) of the 

 Vania type too. In revising the Bockian collection I have distinguish- 

 ed type 1 and 2 in C. ('Fan/rtJ jjamråra by ranging them in two diffe- 

 rent subspecies. 1 have been neither al)le nor willing to discuss tlie 

 innumerable synonyms of this species — A. H. Clark has given an 

 imposing synonym list in Siboga Exp. Vol. 4:2 B. It is not possible to 

 distribute the names of this list among the 2 new sub-species because 

 most of the authors have given no information about the occurrence 

 and appearance of the combs. Even A. H. Clark, who has described 

 hundreds of specimens belonging to this species, has hardly gi^en 

 any other information except about cirri and division-series, li is there- 

 fore natural that he has escaped making the observation that a comb 

 of the Gomaster-i\\)Q also occurs in the sub-genus Vania. Already in 

 my work upon the crinoids of Di- Mjöberg's expedition 1 recorded the 

 statement of P. H. Carpenter filjout the occurrence of the (Jo)iw.dei- 

 type in 'À of the species referred by A. H. Clark to the parvicirra- 

 group. viz. Actinomdra elongata, simplex and quadrala. All the Mjö- 

 bergian specimens, however, had 4 components in the II Br-series and 

 the Coinaster-iy\)e in i-espect of the disti'ibution of pinnules, and conse- 

 quently, trusting to the Clarkian genus-diagnosis, I referi'ed the above- 

 mentioned species, most suitably referable to Vania pjcirvicirra, to the 

 genus Gomaster and assigned the specimens with coarser cirri to G. 

 multifida and those with rudimentary cirri to G. tijpica. Since then I 

 have had an opportunity to establish that the occurrence of combs 

 far out on the arms is not exclusive to the genus Gomaster but is also 

 found in the genus Goinayithus subgenus Vania. 



It is not curious that both these species of the subgenus. Vania 

 have caused great trouble to all authors by their extreme variability 

 in practically all distinguishing characteristics otherwise succesfull\- 

 used. Not only are cirri and cirrals. di\ision-series and Br-segments
