Plate IX. 



Gissocrinus (continued). 

 G. campanula (p. 160). 



Fig. 293. Original of ANGELIN, Tab. XXVII. tig. 1, division y\ seen from anal side. showing stem and 



crown. (pp. 161, 162.) 

 Fig. 294. Original of A.NGELIN, Tab. XXIX. fig. 74 a; from below, showing the partly fnsed IBB. with 



the unfused IB in 1. post. radius. (pp. 161, 163.) 

 Fig. 295. Original of ANGELIN, Tab. XXVII, tig. 1, division «; from below, showing three IBB, the 



smallest or unfused IB beiug in 1. post. radius. (p. 161.) Compare Figs. 294, 296, 308, 



266, 359, 360 and 377. 

 Fig. 296. Specimen 130 RM; from below, showing three IBB, the smallest or unfused IB being in r. 



ant. radius. (p. 161.) 

 Fig. 297. Same specimen; from r. ant. interradius. showing BB higher than usual. 

 Fig. 298. Original of ANGELIN, Tab. XXVII, fig. le, /, g; VIII Br, (a) from back, (b) from side. 



(pp. 162, 163.) 

 Fig. 299. Same specimen; articular surface of a brachial, VI or VII Br, showing ventral groove and 



separate axial canal. The lateral projections, so conspicuous in Fig. 298 have been rubbed 



away. (p. 162.) 

 Fig. 300. Same specimen; articular facet of a rnore distal brachial. showing the axial canal joined to 



the ventral groove. (p. 162.) 

 Fig. 301. Same specimen; ventral surface of brachials, showing covering-plates. from X or XI Br. (pp. 



162, 163.) 

 Fig. 302. Same specimen; portion of ventral sac, showing apparent irregularity produced by ridging of 



the plates. (p. L62.) 

 Fig. 303. Columnals, showing a nuinber of small ones between large projecting ones. Compare with 



G. tyfus, Fig. 283. The sutures between tbe small columnals are very härd to distinguish; 



they are better seen in b, which bas been slightly ground down. This also shows slight ir- 



regularities in the ossicles. (p. 162.) 

 Fig. ;it>4. Same specimen; articular facet of stem. (p. 162.) 



Fig. 305. Bara-Wallstena specimen; brachials seen from back and side. (p. 162.) 

 Fig. 306. Same specimen; articular facet of brachial. Compare with Figs. 299, 300. (p. 162.) 



G. umbilicatus (p. 163). 



Fig. 307. Specimen a, from posterior. (pp. 163, 164). 



Fig. 308. Same specimen. from below. Since the description in the text was written, Air. LILJEVALL 



has succeedcd in removing the stem-fragments tbat obscured the IBB. (p. 163.) 

 Fig. 309. Same specimen; interradial space, showing steep sides of brachials, which join on to tegminal 



plates. (p. KU.) 

 Fig. 310. Same specimen; (a) portion of anal tube from distal region, with portion of an arm seen a 



little from the side and showing covering-plates. (/>) part of the same arm further enlarged, 



showing covering-plates and infilling of calcite which is alluded to as inner plates in the 



text. (c) brachials and covering-plates from the ventral surface. (d) the same in section. 



(p. 164.) 

 Fig. 311. Specimen 6; sections of brachials and covering-plates, of which a is a little more proximal 



than b and c, and has the axial canal a little more defined. (p. 164.) 

 Fig. 312. Same specimen; posterior view, showing an apparent 11'. (p. 164.) 

 Fig. 313. Same specimen; columnals. (p. 164.) 

 Fig. 314. Same specimen; articular facet of a columnal, showing stellate axial canal and very slight 



striations. 

 Fig. '■'>['>. Specimen c; an interradial area, showing the dome-like tegmen. Compare Fig. 309. (p. 164.)
