second collection recently forwarded has not been reported on. The 

 total recorded additions are — Gasteropoda 58, Conchifera 16, Brachio- 

 poda 1 ; but these do not exhaust our knowledge, as I am acquainted 

 with nearly as many more unrecorded species. 



Class Polyzoa. — Some evidence of the neglected state of Australian 

 zoophytology up to comparatively recent times may be gathered from the 

 circumstance that out of fifty-four species of twenty-four genera of 

 Polyzoa described by Busk in the Appendix to "Voyage of the Rattlesnake" 

 (1852), forty species are new or undescribed, and four genera are insti- 

 tuted. Forty-two were collected in Bass's and Banks' Straits, one at Port 

 Adelaide, the remainder off other parts of the Australian Continent. 



Some of our Australian species are common to the seas of Europe » 

 these are described in (t) Johnston's " British Zoophytes." 



In 18G0, Macgillivray, in Trans. Phil. Inst., Victoria, vol. iv., pp. 

 97-98, one plate, and pp. 159-168, two plates (in Library Philosophical 

 Society, Adelaide) wrote upon the Polyzoa of Southern Australia. Four 

 species are credited to South Australia. Professor Hutton's Catalogue of 

 the Marine Mollusca of New Zealand (1873) should be consulted. 



In 1875 there appeared (*) Part III of Busk's Catalogue of the Polyzoa 

 8vo, 34 plates. This contains descriptions of sixteen Australian species 

 of Cyclostomatous Polyzoa, only five of which had been previously 

 recorded — two by Macgillivray and three by Busk, op. cit. (Copies of 

 Parts I. and II. of the Catalogue of Polyzoa are not in the colony, and 

 these portions of the work are out of print.) 



Rev. J. E. Tenison Woods, in Trans. Roy. Soc. of New South 

 Wales (1877), describes two new species of South Australian Polyzoa 

 belonging to the genus Serialaria. 



Hincks, " Notes on the genus Retepora," An. & Mag. Nat. Hist., 

 May, 1878, describes two new species of the genus, and supplies much 

 fuller and more minute diagnoses than we have from the authors who 

 named them — of three others — all of which are stated to have been col- 

 lected in South Australian waters. 



Professor Hutton, in a short paper recently communicated to the 

 Royal Society of Tasmania, describes six new species, and identifies 

 nineteen with known forms. These were collected by myself upon the 

 shores of St. Vincent's Gulf. Some of them are of great interest. 

 Tubulipora flabellaris had not been found in the Southern Hemisphere 

 before, and Vincularia maorica had previously been known only as a 

 miocene fossil.
