Estheria have not been identified. A new species of the former from 

 Peak Downs, Queensland, is described in the " Journals des Museums, 

 Godeffroi," No. 12. 



The only book information that I am in possession of respecting the 

 Ostracodous Crustaceans of Australia is that comprised in the three 

 following papers by the Rev. R. King in f Proc. Roy. Soc. of Tasmania. 

 "On some species of Daphniadae found in N. S. Wales," vol. ii., 

 part ii., p. 243. et seq. (1853) five plates. " On some Australian Entom- 

 ostracans," id. p. 253, three plates, and vol. iii., pt. 1, 1855. In these 

 papers thirty-six species are described all with new specific names, and 

 one new genus is instituted for two of them. 



The (f) " Monograph of the Sub-class Cirripedia," by 0. Darwin, — 

 published by the Ray Society, represents the present state of our 

 knowledge of these Crustaceans, though twenty-four years have elapsed. 

 In Part I Lepadides, 10 pi., 8 vo., 1851, the Pedunculate Cirripedes are 

 described ; eight are recorded from Australia, three of which are 

 peculiar, one Ibla quadrivalvis, being confined to St. Vincent's Gulf , 

 Part II., 30 pi. (1854) is devoted to the Balanidae or acorn shells 

 twenty-two inhabit the Australian shores, eleven of which are peculiar 

 the South Australian species are two of Acaste. 



Class Annelida. — Baird, W. "New species of Tubicolous Anne- 

 lides," Proc. Linnean Society, Vol. vin., three plates, 1864. In this 

 paper are described new species of tube-building worms which form part 

 of an extensive collection of annelides in the British Museum. The 

 family Serpulidas was established by Linnaeus, in which he included the 

 Molluscan genus Vermetus, the shelly tubes of which bear a close resem- 

 blance to those of Serpula. Dr. Baird shows that a more detailed know- 

 ledge of the animals is necessary to fix them with certainty in their 

 systematic position ; thus an examination of the animal inhabiting the 

 tube, named Vermetus cariniferus, by Gray, which inhabits our coasts, 

 has resulted in its removal from the molluscan class of Gasteropods to 

 the family Serpulidae of the Class Annelida. The species described 

 include four from New Zealand and three from Australia. 



Baird. — " Contributions towards a monograph of the species of Anne- 

 lides belonging to the Aphroditacea," op. cit., vols, vhi-ix. The 

 Aphrodites include the sea mice, many of which are remarkable for 

 their size and from being covered with brilliantly-shining and splendidly 

 irridescent hairs. The only South Australian species of the family 

 recorded is Aphrodita Anstralis, Baird, which was obtained at Port
