Plate VIII. 



Cyathocrinus (continued). 



C. ramosus (p. 146). 



Fig. 248. Specimen a; brachials and covering-plates seen from side. Compare Figs. 235, 243 and 210. 



Lettering as before. 

 Fig. 249. The same from the ventral surface. (p. 148.) 

 Fig. 250. Articular surface of brachial, with covering-plates. Compare Figs. 213, 237 and 247. The 



inner piece i is seen, but smaller than in C. acinotubus. (p. 148.) 

 Fig. 251. Specimen a; anal area and tube. 

 Fig. 252. Another specimen, wrongly alluded to in text as a. Calyx from ventral side, showing the 



greater part of the tegmen. Compare Text-tig. 20. (pp. 148, 149.) 

 Fig. 253. Same specimen; articular facet of a columnal. (p. 150.) 



Fig. 254. Specimen /; covering-plates from ventral surface, with marked sbagreen ornament, (p. 148.) 

 Fig. 255. The same from the inner or dorsal surface, showing the articular facets of c 1 and the inner 



pieces i. The latter are distinguishable from the infilling calcite by their darker colour. 



(p. 148.) 

 Fig. 256. Same specimen; articular facet of a brachial. 

 Fig. 257. Specimen 1G0, R. M.; inner surface of radial with attached 1 Br and covering-plates, showing 



entrance of ventral groove and of axial canal and the diverging ridges that protect the 



branches of the axial cord. (p. 147.) 

 Fig. 258. Specimen d (C. zonatus of Angelin); the plates of the cup that are preserved. (p. 147.) 

 Fig. 259. Same specimen; brachials and covering-plates from the side. Compare Fig. 248. (p. 148.) 

 Fig. 260. The same from the ventral surface. Compare with Figs. 249 and 254, especially the former. 



On <; 2 of the fourth covering-plate from the bottom of the drawing is a small spöt, which 



raay be due to a parasite. (p. 148). 



N. Ii. With reference to the colour of C. longimanus and C. ramosus, discussed on p. 151, 



add a reference to Rep. Geol. Surv. Illinois, VIII, p. 160 (1890); received in England after 



the page in question had gone to press. 



Gissocrinus (p. 152). 



G. typus (p. 155). 



Fig. 261. Original of Angelin, Tab. III, fig. 2, showing the general characters of the species. 



Fig. 262. Original of ANGELIN, Tab. XXVII, fig. 1 ö, showing stein and anal area. (p. 157.) 



Fig. 263. Same specimen; columnals. (p. 158.) 



Fig. 264. Specimen w; articular facet of columnal, slightly broken. (p. 158.) 



Fig. 265. A dorsal cup from below, showing the small IB. in r. ant. radius. Compare Figs. 266, 294, 



295, 308, 359, 360 and 377. (p. 156.) 

 Fig. 266. A dorsal cup from below, showing the small IB in 1. post. radius. Compare Figs. 265 &c. 



(p. 156.) 

 Fig. 267 Brachials (a) from the back, showing the rouuded shape and lateral projections, (l>) from the 



side, showing the lateral projections. (p. 156.) 

 Fig. 268. Brachials from back, showing ridged shape and slight lateral projections. (p. 156.) 

 Fig. 269. Brachials from back, showing strong spines, a further development of the i - idge and lateral 



projections. (p. 157.) 

 Fig. 270. Transection of two brachials, showing ventral groove and axial canal. That on the left appears 



to be axillary, as the axial canal has bifurcated. (p. 157.) 

 Fig. 271. Brachials from the ventral surface, showing the covering-plates composed of three elements 



and occasional tninute intercalated plates.
