196 Mr. F. A. Bather on British Fossil Crinoids : 



In the Woodwardian Museum, Cambridge : 



a/493, an almost complete specimen, with the crown slightly 

 disturbed ; seen from right posterior radius. On a 

 slab of limestone. Dudley. In the Fletcher collec- 

 tion. (PI. XI. fig. 3, explanation on p. 194.) 



For permission to figure the first and last of these speci- 

 mens my thanks are here given to Dr. Henry Woodward, 

 F.K.S., and Prof. T. M'^Kenny Hughes. For similar favours, 

 as well as for the loan of the specimens in the Mason College 

 and the Dudley Museums, I must express my gratitude to 

 Prof. C. Lapworth and Mr. \Y. Madeley. 



These specimens all appear to come from the Upper Wen- 

 lock Limestone ; but, as usual, their exact locality and horizon 

 are uncertain. They all belong to one species, for which I 

 propose the name — 



Madigocrinus loreus^ sp. n. 



1873. Cyathocrinus (sp. 9) orboreiis, J. W. Salter, wo?«. tuid., Cat. 



Camb. and Sil. Foss. p. 125 : Cambridge. 

 Kon Ci/athocrinns arboreus, Meek and A\'orthen, Proc. Acad. Nat. Sci. 



Philadelphia for 1865, p. 160, and Rep. Geol. Surv. Illinois, vol. iii. 



p. 520(1868). 

 Cyathocrinus sp. 11, Salter, loc. cit. 



The trivial name applied to this species means " provided 

 with lashes," and, besides carrying on the metajihor of the 

 generic name, it alludes to the very fine terminations of the 

 arms. 



Detailed Description. 



The plates of all the sjjccimens except 57048 B.M. are 

 somewhat displaced, so that the measurements here given refer 

 chiefiy to that. For details connected with the Cambridge 

 specimen I am indebted to drawings furnished b}' 3Ir. Edwin 

 Wilson, as well as to an excellent photograph sent me by the 

 Cambridge Engraving Co.: the spicimen itself I have never 

 seen, as it could never be found when I went to the Wood- 

 wardian Museum ; for information tliat it was at last forth- 

 coming 1 am obliged to ]\Ir. H. Woods. The specimen 

 a/497 which JSalter labelled ^^Cyothocrinus sp. 11," was also 

 thought to be missing:; (see Cat. Tvpe Fossils, Woodwardian 

 Mus. ]). 39, Cambridge, " 1891,""' kS92) ; but, through the 

 kindness of Mr. Woods in sending me a rough sketch of it, 

 1 am able to refer it, as was to be anticipated, to the ju'esent 

 t^pecies. The specimen consists oi a rather disturbed crown,
