74 F. A. Bather — Ordovician Crinoids, 



of from the left side. M. typus is a species of totally different 

 appearance, owing to all its cup-plates and brachials being con- 

 siderably wider than high. To M. eorroboratus, the preserved 

 portion of specimen A presents a close resemblance; the basuls. 

 however, appear to have been higher in proportion, the arms are 

 a trifle more slender in the proximal region, and their distinct 

 though slight imbrication constitutes an appreciable difference. 



Therefore, although Mr. Morton's specimen GSIa is imperfect, 

 the preceding facts, combined with the absence of other known 

 representatives of Merocrimts on this side of the Atlantic, justify 

 its being taken as the type of a new species, which may be named 

 after the county of its origin, and thus diagnosed: — 



Merocrinus Salopice, n.sp. 



ER and BB as high as wide. Arms slender, bifurcating at 

 intervals of eight or more ossicles. Br wider, or with a slight 

 cornice, at their distal margin. 





A. Merocrinus Salopice, 4 times nat. size. a. Lower portion of same specimen, 



9 times nat. size. 



B. An undetermined Inadunate Crinoid, 4 times nat. size. b. Portion of the 



arm, 10 times nat. size. 

 The drawings were made from wax squeezes, by Miss G. M. "Woodward and

Specimen B. 



The plates of the Dorsal Cup are disturbed. A basal and two 

 radials can be distinguished. The radials are comparatively large, 

 and seem irregular in shape. 



The relation of the Arms to the cup seems to be that of an 

 Inadunate crinoid. The arms appear to have been regularly dicho- 

 tomous. That on the right of the drawing has IBr, i ; IlBr, 7 in 

 the left branch, the axillary of which (lIAx) bears one IIIBr on 

 either side. The evidence of the specimen is rather against there
