P. 9, Bibliography. An earlier reference than any here given is to Magnus von Bromells »Mineralogia, eller 

 Inledning til nödig kundskap af igenkiänna och upfinna Allahanda Berg- Arter Mineralier, Metaller 

 samt Fossilier, o. s. v.» 2nd edition, Stockholm, 1739; 8vo, xxiv & 95 pages, & Register 36 pages. 

 The following passage on p. 47 shows that Bromell had a verv fair idea of the true nature of Crinoid 

 remains: »I lika måtto hittar man som oftast uti kalksten på Gottland och i Skåne ett slags små 

 platta/ femkantiga eller triuna tunna enkla/ så och i små leder hopwuxne iholige stenar/ bekante 

 under namn af Entrocho, Trochita, och Asleria columnari, Stiern- och Hiulstenar/ om hvilkas ursprung 

 man fuller ännu ingen futkomraelig [sic] kunskap hafwer / dock hållas de af de fläste naturkunnigom 

 för petrificerade fötter leder och strålar af ett mång-fotat hafsdiur /' stella marina och meditsw cajntt 

 kallad.» A German translation of this work by Mikrander, under the litle of Mineralogia et Litho- 

 grapica suecana», was published in 1740; in this edition the above-quoted passage occurs on p. 83.

» 38, end of 5th paragraph, Add: — That this statement of the case is by no means exaggerated may be seen 

 by reference to Mr. D. P. Oehlerts recent paper 'Description de deux Crinoides nouveaux du Dévonien 

 de La Manche' (Bull. Soc. Géol. Frauce (3) XIX, pp. 834—853, pl. XVIII; Dec. 1891). On p. 

 849 he discusses Herpetocrinus, concluding thus: »Nous ferons d'abord observer que les espéces qui 

 ont été réunies sous ce nom par Angelin possédent des caractéres assez différents pour devoir étre 

 réparties dans des genres distincts; ensuite, qu'il n'est nullement prouvé qu'aucune des formes du 

 Sibirien de Suéde se rapporte au genre de Hall, qui, d'ailleurs, est toujours tres problématique, puisque 

 les fragments d*aprés lesquels il est établi, sont pour les uns des brås, hypothése a laquelle se sont 

 rattachés MM. Wachsmuth et Springer, et pour les autres des troncons de tige.»

 by Mr. D. P. Oehlert {loc. cit.), without however clearing up any of the difticulties.

After the sheet containing the description of this species had been printed off, the larger specimen 

 was verv carefully cleaned by Mr Liljevall, who thus made, the fortunate discovery that it did
