160 P. A. BATHER, CRINOIDEA OF GOTLAND. 



ever, the species is quite different, since they pass in almost a straight line upwards from 

 the cup. 



The covering-plates are not very clearly seen; but they appear to have had essenti- 

 ally the same arrangement as in G. typus (tig. 288, 289). Not quite so many, how- 

 ever, go to a brachial, in consequence of the less height of the latter in the present 

 species. 



I J>r 1 ; tri hedra 1, with curved sides. Angelin's statement, that there are two 

 of these plates of which the distal one is minute, is probably due to an error of ob- 

 servation. 



IIBr 2, low and wide. 



IIIBr 2 — 4 = and 3 — 5 = the higher numbers being on the inner side 1 ). In this 

 series there are sometimes low patelloid plates, a feature cominon in the Articulata but 

 rare in Inadunata. 



IVBr 4— 7— 6— 4 = and 4—6—8—5 = 4—8—8—4. 



The Anal structures are unseen in a, but in b a proportion of the ventral sat- 

 is visible and is seen to be as in G. typus; it is, however, much weathered and, owing 

 to the backs of the transverse ridges having been rubbed down, presents the appearance 

 of pores (figs. 290, 292). 



The St em is apparently as in G. typus. 



Notes on Angelin\s figures: 



Tab. III, fig. ö. This is an incorrect and very wooden restoration. The cup waä 

 certalnly broader than here shown. 



Tab. III, fig. 5 a shows the character of the ornament, but is not strongly enough 

 marked. 



Locality: a from between Endre and Follingbo; 6 from quarry between Bara and 

 Wallstena; bed f. Not known out of Gotland.

Diagnosis. 



The closed crown is bell-shaped, its greatest width being at the level of VIBr. 

 Dorsal Cup a very low wide cone; its plates marked with radiating ribs formed by the 

 concrescence of granules. [BB very 1<>w. BB wider than high. RR lunate; with facet 

 from (i to 8 of width. IBr 1, low. HBr 1, verv rarely 2; laterally apposed. Arms 



') The si^ii = denotes the raiddle line of the ann.
