Since the present authors restrict the termbraehialia to the free ossicles, they should not translate it by piecesbrachiales (p. 5). A similar error as to articles brachiaux occurs on p. 17of Wachsmuth and Springers Crinoidea Camerata. The term route(vault) connotes a structure now admitted by all to be imaginary; whilethe terms trompe (proboscis) and canal nourricier (alimentary canal) areequally misleading. The well-known term cirri, though introduced onp. 9, is replaced in practice

The well-known term cirri, though introduced onp. 9, is replaced in practice by the term vrilles (tendrils), which is nogain. Again, the term calyx is defined on p. 3 in the sense in whichit has been used by Wachsmuth and Springer and others : the employ-ment of the word calyx to designate that part which is only the dorsal Lower Palccozoic Crinoids of Bohemia. 105 Beyrichocrinus humilis, the sole species of the genus,conies from the limestone f 2 of Koneprus *. Only the cupis preserved (Fig. 1). It consists of the following primary DAx .analia. Fig. 1. -Analysis of the cup of Beyrichocrinus humilis, outlines copiedfrom Waagen and Jahn, and about twice nat. size. Inter-brachiala (ilBr) and anals are shaded from right to left;intersecundibrachs (illBr) from left to right; intertertibrachsvertically. elements: 3 basals, 2 large and 1 small; 5 radials, whichappear to abut laterally by short sides, except in the posteriorinterradius\ 2 fixed primibrachs in each ray, the first beinghexagonal except in the right and left posterior rays ; 2 fixedsecundibrachs in each half-ray; 2-4 fixed tertibrachs, ofwhich the last is axillary and bore the free secondary elements of the cup are: 5-10 interbrachialsarranged in 4-6 horizontal zones, the proximal interbrachialresting on the steep shoulders of two adjacent radials andcoming very near to the basals ; in the wider anal inter-radius are about 14 interbrachials (anals), of which the cup is an abuse.
