Gissocrinus verrucosus (continued). 



Fig. 361. Same specimen; in natural position on matrix. (pp. 171, 172.) 



Fig. 362. Same specimen; radial and facet, slightly restored from the evidence of two exposed facets iu 



the specimen. (p. 171.) 

 Fig. 363. Same specimen; brachials from the side, sliowing covering-plates. (p. 171.) 

 Fig. 304. Same specimen: brachials scen from hack. as exposed at the back of the specimen: III Hr 



or IV Br. 

 Fig. 365. Same specimen; ventral surface of the same brachials, with covering-plates partly renioved, 



exposing ventral groove and axial canal. (p. 172.) 

 Fig. 366. Same specimen; the upper articular surface of one of these brachials. without covering-plated 



(p. 172.) 

 Fig. 367. Same specimen: II Br from ventral surface, with covering-plates which are indented, probably 



owing to conditions of preservation. (p. 172.) 

 Fig. 368. Same specimen; articular surface of II Hr, sliowing indented covering-plates. Compare Fig 



367. (p. 172.) 

 Fig. 36!). Same specimen; plates from the proximal part of the anal tube, sliowing imbricated charactcr 



produced by ridges. di. 172.) 

 Fig. 370. Same specimen; a single plate of the anal tube, further enlarged. (p. 172.) 

 Fig. 371. Same specimen; columnals from the side and viewed a little from ahove. (]». 172.) 

 Fig. 372. Same specimen; articular surface of a columnal, sliowing quinquelobate axial canal. Compare 



with Fig. 355. (p. 172.) 

 Fig. 373. Another specimen, from 1. post. radius. (p. 172.) 

 Fig. 374. Same specimen; the calyx and lower part of the anal tube enlarged, sliowing ornament of 



cup-plates and I Br, tegmen, covering-plates of anterior arm and strueture of tube. (p. 172). 

 Fig. 375. Same specimen; columnals, which are of three sizes, d, b and c (p. 172.) 

 Fig. 376. Another specimen; articular facets of brachials. (a) I Br, (b, c) II Br. Xote curious shape 



of axial canal. Compare Fig. 358 and contrast Figs. 357 and 368. 

 Fig. 377. A young individual; the crown from below, with outline drawing of the cup-plates. (p. 172.) 

 Fig. 378. Same specimen; plates of the anal tube. Compare Figs. 30'.) and 374, sliowing that the 



imbrication is mit so developed in the young. Between the plates are appearances of slits 



and pores, as in Fig. 334 and due to the same cause. (p. 172.) 



Gissocrinus sp. (p. 173.) 



N. B. In reference to Plate-tigures, for 402 read 382. 

 Fig. 379. Dorsal cup, from r. ant. radius. 

 Fig. 380. The same, from post. interradius. Anal x is absent and 1. pust. i; is eitlier broken or al>- 



normal. (p. 174, referred to wrongly as Fig. 400.) 

 Fig. 3X1. The same, from 1. post. interradius. The 1. post. and 1. ant. RH support a deltoid. Otber 



tegminal plates are seen. 

 Fig. 382. The same, from below, sliowing the single attached columnal and the 5 IBB.
