The arms are about 30 mm. long. 



P, is about 9 mm. long with 21 segments which have spinous distal borders. Pj is 

 about 4 mm. long. 



The arms and pinnules resemble those of A. bifida moroccana, and there are promi- 

 nent clusters of perisomic interradials in each interradius. 



Localities.— ^\o de Janeu-o, Brazil (Bohlsche, 1866; P. H. Carpenter, 1888] (1, 

 presumably Gottingen Museum, A.M.C.). Tj'pe locahty. 



Blake station 262; off Grenada (lat. 12°01'45" N., long. 61°47'25'' W.); 168 meters; 

 temperature 16.67° C; fine sand; Marcli 1, 1879 [Hartlaub, 1912]. 



St. Thomas, Vu-gin Islands; II. Koch, 1860 (1, CM.). 



Geographical range. — From Rio de Janeiro, Brazil, northward to St. Thomas. 



Bathymetrical range. — From the shore line down to 168 meters. 



Thermal range. — One record, 16.67° C. 



History. — This species was first described by Dr. Wilhelm Bohlsche from a single 

 specimen taken at Rio de Janeiro; but previous to this, in 1860, an example had been 

 collected by Mr. H. Koch at St. Thomas and sent to the Copenhagen Museum where 

 it had received the manuscript name of Antedon antillensis from Prof. C. F. Liitken. 



In 1888 Dr. P. H. Carpenter redescribed and refigured Bohlsche's type specimen, 

 which was sent him from Gottingen through the kindness of Dr. Otto Hamann; but 

 his account of the species is somewhat obscured by the fact that he identified with it 

 a young example of Tropiometra carinata, which the Challenger had obtained at Bahia, 

 Brazil, in 36 meters. 



In 1891 Carpenter decided that this species is synonymous with Antedon bifida. 



It is most probable that the very poor specimen described by Hartlaub in 1912 

 under the name of Antedon liathra represents tliis species. 



In 1914 the specimen collected by Mr. Koch at St. Thomas was first recorded. 



Considering the great amount of collecting that has been done along the shores of 

 the West Indian islands it is certainly surprising that this species has not been more 

 frequently taken.
