form Halipteris blakei. The place of discovery was the Gulf of Georgia, Burrard's Inlet (comp. also 

 Proc. Calif. Acad. Sc. Vol. V, 1873, pi. I, pp. 7 12). From the description given I would not maintain 

 as a certainty, however, that this species is not a Pavonaria K611., and at all events nothing more 

 particular can be said as to its specific difference from Halipteris christii. The description of the 

 calcareous axis with its lower enlargement agrees with both genera. The specimen from the same 

 locality, described and figured by Moss (Proc. Zool. Soc. Lond., 1873, P- 73)) undeniably reminds one 

 most of a Pavonaria; but neither the description nor the figure yields any reliable basis for a determin- 

 ation. Naked calcareous axes of the same forms have been described by Gray (Catal. Sea- Pens, 

 p. 40; Ann. Mag. Nat. Hist. (4), IX, p. 405, X, pp. 77, 406) as Osteocella septentrionatis* from the west 

 coast of America, and others similar as Osteoc. ciiftoni^, possibly from West-Australia. Thus the 

 genera Halipteris and Pavonaria are probably rather widely distributed in the Indo-Pacific Ocean.

South of Iceland the Ingolf has obtained a young specimen of a length of 225""; the length 

 of the peduncle cannot be decided with certainty, as the soft parts of the lower part of the rhachis 

 have been scraped off; otherwise the specimen is very well-preserved; the polyp-calyxes up to 3.5""" 

 long. In appearance it is strikingly similar to the Trichoptilum bnmneum of Kolliker (Rep. Chall. 

 Penn. PI. VIII, fig. 31), and agrees also with the Leptoptilum gracile var. noroegicum of Koren and 

 Danielssen 1. c. PL XIII. The polyp-calyxes are richly provided with spicules, the arrangement of 

 which quite agrees with fig. 3 of PL XIII of the last-mentioned work; again, the tentacles are also 



') Bohadsch is stated by Kolliker to be the author who has given the earliest description of the species in: De 

 quisbusdatn Anhnalibus Marinis, etc. Dresdae 1761. Here it is mentioned, chap. VI, p. 101 under .Penna.T, as no. 3, P.rubescens 

 ( pinnis carens, tentaculis in corporis trunco positis >) and p. 112 as a species neglected by science, but known to fishermen 

 who called it Penna del pesce pavone. His specimen which was incomplete, was of a length of 2 feet 10 inches (inulto 

 vero longiorem earn fuisse non dubito>), and has probably been from the Mediterranean (Naples? from which locality he has 

 several things i. However, I have found this species mentioned as early as 1655 in Museum Wormianum p. 235: PennaL-
