MONOGRAPH OF THE EXISTING CRINOIDS. 37 



of the Caribbean Sea, and made known the remarkable new genus Atelecrinus, 

 assigning to it three species, Atelecrinus bdlanoides (sp. nov.), A. cubensis (Antedon 

 cubensis Pourtales, in jiart; immature A. balanoides), and A. sp. (Atelecrinus 

 wyvittii). In addition he described the interesting Antedon spinifera (Stylometra 

 x/iinifera), and first recorded (in that species) the presence of a complete ambulacral 

 plating in a comatulid comparable to that found in the pentacrinites, while he also 

 figured, without giving a formal description, the extraordinary form which he 

 called Antedon columnans (Zenometra columnar! s). In the same year he reported 

 upon the rich comatulid collection of the Leyden Museum (which had previously 

 been studied by Miiller), and laid the foundation for knowledge of the remarkable 

 comatulid fauna of the East Indies. 



The species which he discussed in this paper were:

In 1882 he further elucidated the East Indian fauna hi a similar paper on the 

 coiuatulids of the Hamburg Museum, in which he also takes up the peculiar genus 

 Ophiocrinus (Semper, 1868), changing the name to Eudiocrinus (Ophiocrinus being 

 preoccupied), and describing some additional species, which have recently been 

 shown to have only a very remote relation to the original Ophiocrinus indivisus. 



The comatulids considered in this paper are: 



Atelecrinus balanoides Atelecrinus balanoii/, s. 



. 1 /,/, i-i-in us cubensis Atelecrinus balanoides. 



Atelecrinus wi/rillii, sp. nov itekcrinui wyvillli.
