30 TORSTEN ULSl.ÉN, CRINOIDS. 



21 — 25, 7 — 10 mm. First two segments a little bulbously swollen, the others verv 

 tliin and slender. - P il (on Br 4) corresponds approximately to P l7 1\ corresponding 

 to P 2 etc 



Mouth somewhat displaced laterally. Anus subcentral. Peristom with lime 

 grämdes. 



Colour dark red (in spirit deep red-brown). Oral pinnules often white-coloured 

 at the tips (for instance in specimens No. 3, 14 and 15). Two specimens from St. 

 10 with Eulima sp. 1 



From Station 4 all the specimens present segments of a niore or less rough 

 appearance and the arms feel scabrous. Median, dorsal prominences at the proximal 

 segments are less developed. Basal parts of the arms have the lateral processes more 

 perfected, by which the animal appears more wall-sided. I mention this type as a 

 form scabra. 



In order to ascertain the extent of the variability in the number of the cirri, 

 cirrals and segments of proximal pinnules I have carried out an investigation on the 

 accessible specimens, which is as follows: 



I = C:i in the inner, E = C:i in the exteriör row. 



B= posterior lath, A = anterior processes. 



N. B. In counting the pinnulars I have paid minute attentioii to the fragile 

 tip not being broken, which has happened very often. If this fact is not taken into 

 account one löses a number of 2 to 4 pinnulars when counting the segments.

1 Dr. Nils Odhnbk, Stockholm, to wliom 1 delivered the species fur dctermination, has kintlly given t lie 

 following statement. The largest specimen, attaelied on Centrodorsalc of Oligometra adconce, is 1,5X0,7 mm 

 and has nearly 8 turus. 1'ossibly itlentical with Eulima capillastericola of Bartsch, but as the description of 

 tias species does not contain anything specially characteristic and i- not accompanied by auy jilate. it cannot 

 with certainty be identified. The less so as even full-grown species of the genus Eulima are extremcly difficuU 

 io determine on account of thcir slightly characteristic exteriör and the absence of a radula.
