answers to the description of the Comatula carinata Lamck. (Leach, sp.). It

 differing only in some minor details from the Brazilian ones." Carpenter,

"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. Pourtales (Bull. Mus. Comp. Zool., 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. 

 E. 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- 

 cifically. This conclusion is confirmed 

 by the resemblance between the dissec- 

 ted calices of specimens from Bahia and 

 Zanzibar. They are so very similar 

 that, if they were fossils, I should un- 

 hesitatingly refer them to the same spe- 

 cies. In fact, the Bahia specimens vary 

 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. Zool., 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- 

 gefuhrten 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.
