2IO Excursion to Bazv Baw. [vok'xxx. 



on the contents : — Algae. — Most of the algal constituents of the material 

 are unicellular, only four lilamentous forms being noticed. Diatoms 

 are abundant, but of the several species represented those most common 

 are of the genus Navicula. Of the Desmids the following genera in 

 order of numerical occurrence are present : — Cosmarium, Closterium, 

 Netrium, Penium, and Staurastrum. Of green filamentous alga? only 

 sterile Mougeotia occurs, but of the Myxophycea?, or blue-green algae, 

 there is one species of Anabcena, two of Oscillatoria, and one of 

 Haplosiphon. Rhizopoda. — -The sphagnum also harboured many rhizo- 

 pods, as is the case in other countries, and I have noted species of 

 Amoeba, Vampyrella, Diffiugia, and Pontigulasia. — A. D. Hardy. 



All were so enamoured of the trip that it has been suggested 

 to spend a week on the plateau, towards the end of next Novem- 

 ber, about the height of the season for the alpine flowers, when 

 the experience gained on the recent trip would be of great 

 service to those then able to go. — F. G. A. Barnard. 



LIST OF RECENT VICTORIAN BRACHIOPODA. 



By J. H. Gatliff and C. J. Gabriel. 



{Read before the Field Naturalists' Club of Victoria, 12th Jan., 19 14.) 



In 1890 the Royal Society of Victoria published a "Census of 

 the Victorian Brachiopoda," by A. H. S. Lucas ; it comprised 

 five species. Some of the generic names have been altered 

 since, and we are enabled to add four more species, and now 

 give a list of the whole of them, with references. 



The Brachiopocls used to be included in the Mollusca, but 

 during recent years they have been separated, and are now 

 classed with the Molluscoida, of which the other divisions are 

 Tunicata and Bryozoa. 



The Brachiopods or lamp shells are marine bivalves, 

 stationary, being usually attached by a muscular pedicle or 

 peduncle, which is situated near the apex or beak of the lower 

 valve. The animal has a \)^\r of ciliated oral arms, which 

 cannot be protruded from the shell. It has no fool and no 

 true gills. 



The valves are calcareous and finely ])erf()rated, and in llie 

 TerebratulidcT the upper valve is furnished interiorly witli a 

 shelly loop. The sexes are separate.. 



Tryon states that over 4,000 extinct species of Brachiopods 

 have been described from the Cambrian strata and u]:)wards. 

 Davidson, in his excellent monograph,* published in 1886, 

 lists 130 living species. Many discoveries have been since 

 made. Their distribution, both fossil and living, is world- 

 wide.
