A. H. Clark in a letter to me writes about both these species as 

 follows: »The species of Coinasicriiifc are the most difficult of all fri- 

 noids — 1 may even say of all the Kchinodei'ms — to determine. The 

 two species which 1 call paivicirra and annukda are very likely arbi- 

 traiy di\isioiîs of one type; but it is (-(»nvenient to call the smaller 

 individual with -iO or fewer arms parvicirra and the larger with 'M) — 

 70 arms' anniihUa. Many specimens of the latter with the 111 Br 

 series 2 are practically indistinguishable from cei'tain species of Goiaan- 

 theria . .» 



Accoi'ding to this division Comaskr tijpiva Sp. 2 Mihi 1910 would 

 be assigned to Vania amudata. Nevertheless it corresponds closely 

 with the other specimens in the Mjöbergian collection and has also 

 unusually short arms and therefore 1 should be disposed to include it 

 in Vania parvicirra. 



As to the reason of the polyformiiy (d' this subgenus 1 will only 

 point to the following: 



It is possible that the two species of Vania have become a laib- 

 bish heap foi' divers species difficult of solution or types inconve- 

 nient for the systematist. In such a case it would be possible to put 

 order into the now confusing multitude and to get a sur\ev over the 

 existing types by a detailed description (d' specimens. Characteristics 

 that might perhaps be a])plied wouUI be the numbei'. presence or ab- 

 sence of eiri'i. the br of the arm-bases, the appearance and formation 

 of the Ijr-segmenis, of the disision series, of the pi'oximal (and also 

 distal) ])innules and pinnulars. of the disk and eventually of calcareous 

 spicules, that is to say the inclusion of all charactei'istics antl then an 

 examination (d' a large material.
