b F. A. BAT11EK, CRINOIDEA OF GOTLAND. 



as the siinplest lönns of Crinoids, and as least removed from the type whence all families 

 of Crinoids have sprung. In Gotland the Inadunata are represented by at least 40 speeies, 



whieh are here deseribcd, and possibly by a few other speeies still doubtful, whieh are 

 set aside for the present in the hopes of better material eoming to light. Of these 40 

 speeies 18 were founded by Angelix, 1(i are quite new and the rest have been previously 

 deseribed by other authors. These speeies are referred to 10 genera, of whieh one is 

 here proposed for the first time, viz., Gothocrinus, while one, Homocrinus to wit, has not 

 hitherto been recorded from Europé. These genera in their tura are distributed ainong 

 7 families, none of whieh are new. The following is a list of the speeies, in the order 

 of their description, with the horizons from whieh they eonie. The meaning of the hori- 

 zons and their letters is given in a note, p. 15.
