the 3 1>;ism1s and the i', post. and r. ant. inferradials below. The draugbtsraan has, how- 

 ever, dwelt ;i little too lovingly on the characteristic Vnshape of the stem-faeet. 



Localities in Gotland: Follingbo (f); also Bruten, N. of Klinteberget (f) and 

 Lilla Carlsö (f) coll. F. A. 15. L892. I believe thal this species also occurs at Dudley, 



England. 



Calceocrinus interpres, n. sp. 



(Plate IV, figs. 123—128.) 



Diagnosis. 



Proportions of cup are, beight 1; width 1.2; width at hinge l.i; thiekness O.s. 



Cup scen from 1. ant. radius is nearly twice as wide at the hinge end as at the origin of 

 the arm; the sides slope inwards equably. 1. ant. R s and B' united by their apices. T-piece 

 apparently very small, x a broad, stout plate; rests on remains of T-piece and on infer- 

 radials. 1. ant. arm considerably larger than the larger branchcs of the axil-arras; appa- 

 rently simple. Ant. and 1. post. arms have main-axils up to Max. IBr 2. Axil-arras 

 follow the normal type; their larger branches gradually decrease in size. The proxiraa] 

 ossieles of the abanal branches are not seen, and probably no part of those branches was 

 visible when the arms were closed. Hinge with cross-processes indistinct. Ornament ml. 

 The stem-ossicles have a sagittal elevation. 



This species is founded on a single but very fine and complete specimen that was 

 cliscovered in the year 1890 by Mr. G. Liljevall. 



Description of the Type-specimen. 



General appearance of crown not unlike that of C. nitidus, but larger and slightly 

 inore massive. 



Dorsal cup: The outline as seen from the 1. ant. radius is niore oblong than in 

 previous species, with sides sloping equably in from the hinge to t lic left anterior arm. 

 The measurements are, — height 10 mm.; width at hinge 12 mm.; width half-way up 

 10.5 mm.; width above 7 mm.; thiekness 8 mm. 



Base: Width 11 mm.; height to stem-faeet about 4 mm. 



Basals, 3 observed. Left basal appears to reach the stem-faeet. and it extends almost 

 the entire width of the hinge. The suture between the left basal and the posterior basal 

 is only slightly sinuous, the corresponding suture is not seen. The relations of the post., 

 r. post., and r. ant. basals are not clearly seen as the stem is in position. 



Radials: 1. ant. B, — the two halves are united, but the apices of the triangles, 

 instead of exactly meeting, overlap, so that the suture between the two halves is aslant: 

 the infer-radial is deeply excavated on the hinge margin, its width there is about 3 mm., 

 its height is about 7 mm.: the super-radial has a width of 5.5 mm., a height of 4 mm. 



Large radials: these resemble those of C. nitidus, but, since they do not meet one 

 another, have one. side less. Their extreme height is 10 mm.
