VII. — Alg^ FROM Queensland. 



Two small collections of Algae were examined. The first one 

 was made by Dr. T. L. Bancroft at Beaudesert. It consisted of a 

 mass of vegetative filaments of various genera of Green Algse, 

 amongst which were other smaller forms, mostly Diatoms. 



The vegetative filaments comprised three sterile species of 

 Sinrogyra, two of Mougeotia, and one of (Edogonhim. Amongst 

 them were Cosmarmm Begnellii Wille, Glceocystis gigas (Kiitz.) 

 Lagerh., Oscillatoria tenuis Ag., and the following Diatoms : — 



Melosira varians Ag., Synedra Acus (Kiitz.) Grun., S. Ulna 

 (Nitzsch) Ehrenb. var. splendens (Kiitz.) V. H., Gomi^lionema Aiigur 

 Ehrenb. var. Gautieri V. H., Cocconema lanceolatum Ehrenb., 

 C. pai'vicmW. Sm., Epithemia turgida (Ehrenb) Kiitz., Bhopalodia 

 gibba (Kiitz.) O. MiilL, and B. gibberula (Ehrenb.) O. Miill. 



The second collection was made in North Queensland by Mr. 

 E. Muir, of Brockenhurst, early in 1910. There were three tubes, 

 one from a small stream at Mosman, one from a backwater of the 

 Big Mosman Eiver, and one from a backwater of the Little Mos- 

 man Eiver. These localities are respectively abbreviated in the 

 following list to " M.," " B. M. E.," and " L. M. E." Several of the 

 Algae are of considerable interest, and all three tubes contained a 

 rich assortment of Diatoms, one of the most abundant of which 

 was Desmagonium Bahenliorstianum Grun.
