PART 5 A MONOGRAPH OF TflE EXISTING CRINOIDS 491 



History. — In his preliminary account of the comatuUds obtained by the Blake, 

 published m 1881, Carpenter said that among the large number of individuals of Antedon 

 [i.e., Coccometra] hagenii from the Florida Straits he found a few examples of a species 

 with no pinnules at all on the second and fourth brachials, though the other pinnules 

 were developed as usual. 



In the Challenger report (1888) he inserted the name "dejecta, Carpenter, MS" in 

 a key to the species of "Antedon" which he was unable to place in any of the "groups" 

 into which he divided the 10-armed species. In his list of the known species of 

 "Antedon" he inserted "dejecta, Carp., MS., Caribbean Islands, 77-242 fathoms". 



After Carpenter's death the Blake material was turned over to Dr. Clemens Hart- 

 laub, and by hhn was assigned for preliminary study to Dr. Wilhelm Minckert. In 

 1905 Mmckert published some notes on the distribution of the syzygies and the pinnu- 

 lation, as well as on regeneration in this species. 



In the Blake material Hartlaub found only two spechnens of //. dejecta, a larger and 

 a smaller, with no locality label. Both of these appeared on a plate which had already 

 been prepared by Carpenter, and there is no evidence that the latter had had any others. 

 Hartlaub described these in detail, accompanied by figures of each, prepared by Car- 

 penter, and also original photographs of both. 



[Note by A.M.C] Neither of these specimens appear to have been preserved, 

 presuming the above locality list includes the specunens in the M.C.Z. (where the Blake 

 specimens belong) as well as those in the U.S.N. M. The basis for the species must 

 therefore be the description and figures given by Hartlaub. 



In the report upon the IngolJ crinoids (1923) the range of this species was given, 

 based upon unpublished as weU as published data.
