UNIDENTIFIABLE SPECIES. 

 ANTEDON IMPINNATA (P. H. Carpenter). 



Antedon impinnata von Graff, Challenger Reports, vol. 10, Zoology, 1884, pp. 15, 

 16, 18 (nomen nudum). — P. H. Carpenter, Challenger Reports, vol. 26, Zool- 

 ogy, 1888, p. 206. 



Remarks. — The very short description of this species reads: "The 

 third, fourth, and fifth brachials have no pinnules; eight or ten cirri 

 of twelve joints," which would be now expressed: P , P 2 , and P & 

 absent; cirri VIII-X, 12. Carpenter further says that this "is a 

 little species, which was obtained at Mauritius by Professor Mobius, 

 who was kind enough to show it to me when I visited Kiel." 



The type is recorded as having been taken in North Bay, Mauri- 

 tius, at a depth of 15 fathoms.
