“Liitken has given the MS. name Antedon brasiliensis to a ten-armed Comatula which is 
abundant on the coast of Brazil. It was described by Mr. Pourtalés (Bull. Mus. Comp. Zodl., 5, 
p. 214) as answering ‘to the description of the Comatula carinata Lamck. (Leach. sp.)’ from Mau- 
ritius, and as differing only in some minor details from Zanzibar specimens of A. carinata. Rath- 
bun has spoken to the same effect (A 
list of the Brazilian Echinoderms, Trans. 
Conn. Acad., 5, p. 151), and though I 
was at first inclined to follow Liitken in 
separating the two types, further study 
has led me to believe in their specific 
identity. By the kindness of Prof. 
Mobius of Kiel, I have been enabled to 
examine specimens of A. carinata from 
Mauritius. This is the original locality 
of Miiller’s type specimens, which Prof. 
EK. von Martens courteously permitted 
me to study in the University Museum 
at Berlin. I have also seen specimens 
from Chili, Madagascar, St. Helena, the 
Seychelles, the Red Sea, and Aden, and 
find it impossible to separate them spe- 
by the resemblance between the dissec-. 
ted calices of specimens from Bahia and 
Zanzibar. They are so very similar Fia.10. A.carinata Lamck. Armstiicke von verschiedenen

considerably inter se, and there is less 
likeness between two calices from this locality than between one of them and a calyx from Zan- 
zibar. A. carinata is described by Rathbun as probably ranging along the Brazilian coast from 
Rio Janeiro to Pernambuco. It was not obtained by the “Blake” at all; but it was found in 
abundance by Captain Cole, of the ‘‘Investigator” in 278 fathoms, off St. Lucia, so that it may 
fairly be considered as belonging to the Caribbean fauna.” (Bull. Mus. Comp. Zoél., 1881, 9, 
p. 157, 158). : 
Von diesen Angaben ist das zuletzt Gesagte besonders bemerkenswerth. Wenn 
der “Investigator” A. carinata ‘‘in abundance”’ bei St. Lucia fischte, so werden 
wohl mehr Exemplare von St. Lucia vorhanden gewesen sein, als die oben an- 
gefiihrten sieben, welche ich nach Carpenters Tode erhielt. Ferner ist es wun- 
derbar, dass der ‘‘Blake,”’ welcher doch mehrfach bei St. Lucia fischte, kein 
einziges Exemplar erbeutete.
