 This paper is devoted to a study of the speci- 

 mens of Middle Devonian crinoids in the col- 

 lections of the U. S. National Museum and 

 Massachusetts Institute of Technology. The 

 new genera Tripleurocrinus and Tylocrinus 

 are instituted with T. levis, new species, and T. 

 novus, new species, as the respective type spe- 

 cies. Three new species of Megistocrinus are 

 described and figured, while remarks upon 

 known forms are given. Under the genus 

 Dolatocrinus two new species are described, 

 comjnents upon 10 other species of the genus 

 made, and the new name Dolatocrinus wachs- 

 muthi is proposed in place of Dolatocrinus 

 lyoni Wachsmuth and Springer, the latter 

 being preoccupied. In addition, comments 

 upon G other genera and 7 species, notes upon 

 calyx abnormalities, and a table showing the 

 distribution of Devonian crinoids are given. 

 All of the figured specimens are the property 

 of the National Museum.
