In November, 1906, Professor F. Blochmann, of the 

 Zoological Institute of the University of Tubingen, wrote 

 to Professor Stirling, Director of the Adelaide Museum, re- 

 questing the loan of its Brachiopod material, so as to permit 

 of his investigating the South Australian forms. He was 

 working up the Brachiopods of the Valdivia and Gauss 

 Expedition, and had been led into some important questions 

 concerning the geographical distribution of the members of 

 this group. As the Museum material was meagre, Professor 

 Stirling passed the letter on to me, and I sent Professor 

 Blochmann all our well-known forms, and as many other 

 species as I had then separated, from the shells dredged 

 during several years. 



In the early part of this year he forwarded a communi- 

 cation to be used at my discretion, either as a paper by 

 Professor Blochmann, presented by me, to be published in 

 the Transactions of the Royal Society of South Australia, or 

 as material for me to use in compiling a paper of my own. 

 To combine the two ideas seemed the proper course, and 

 with the acquiescence of the Council I present a paper on 

 the Brachiopods of South Australia, which will deal with all 

 the species hitherto found in our waters, and will incor- 

 porate Professor Blochmann's descriptions of his three new 

 species, translated from his manuscript, and attributed, as 

 they should be, to him as their author. We are indebted 

 to him for the photographs of his three species. My remain- 

 ing material has supplied two other new species, which I have 

 described and figured. 



The late Professor Tate, in a Revision of the Recent 

 Lamellibranch and Palliobranch Mollusca of South Aus- 

 tralia, Trans. Roy. Soc. of S. Austr., vol. ix., 1886, p. 76 to 

 p. Ill, enumerated five Brachiopods, namely, W aldh eimid 

 flavescens, ■ Lamarck, now called Magellania flavescens; 

 Terebratella cancellata, Koch, now Terebratulina cancellata ; 

 Megerlia willemcesi, Davidson, which was a misidentifica- 

 tion, and is the Magasella vercoi, Blochmann, n. sp. ; Kraus- 

 sina lamarckiana, Davidson, which remains unaltered : and
