THE VOYAGE OF H.M.S. CHALLENGER. 



Chorological Synopsis of the Species. 



1. Anthenea acuta, Perrier. 



Goniodiscus acutus, Perrier, 1869, Ann. Sci. Nat., 5e Ser., t. xii. p. 280. 



Anthenea acuta, Perrier, 1876, Reris. Stell. Mus., p. 275 (Archives de Zool. exp^r., t. v. p. 91). 



Locality. — Port Jackson. Depth 6 to 15 fathoms. 



2. Anthenea tuberculosa, (hay. 



Anthenea tuberculosa, Gray, 1847, Proc. Zool. Soc. Lond., Part xv., p. 77 ; Ann. and Mag. Nat. Hist., 

 vol. x. p. 198 ; Synop. Spec. Starf. Brit. Mus., 1866, p. 9, pi. iv. fig. 1. 



Locality. — Station 187. Booby Island, Torres Strait. September 9, 1874. Lat. 

 10° 36' 0" S., long. 141° 55' 0" E. Depth 6 fathoms. Coral mud. Surface temperature 

 7 7° 7 Fahr. 



Remarks. — A single fine example was dredged off Booby Islaud, which I refer to this 

 species. The rays are rather longer and narrower than in Gray's figure ; and the super- 

 marginal plates are not furnished with the isolated tubercles on the upper end of the 

 plates shown in that example. They bear large granules, and in this respect resemble 

 an example from Port Essington preserved in the British Museum, which has been 

 referred by Perrier to Gray's species. In the Port Essington example the supero- 

 marginal plates are not so high and broad as in Gray's figured specimen. In the 

 character of its supero-marginal plates the example from Booby Island appears to occupy 

 an intermediate position. The lateral series of abactinal plates on the outer part of the 

 ray which intervene between the median radial series and the supero-marginal plates bear 

 a small group of granules. 



2a. Anthenea tuberculosa, Gray (?), juv. (PI. LVI. figs. 5-8.)

Remarks. — I have placed provisionally a single small example of Anthenea taken in
