and is of some interest as being the first instance in wMcIi tlie 

 genus has been obtained in a fossil condition. The genus was 

 founded by Sandahl for a group of arenaceous Foraminifera 

 built up of very fine sand grains, and takes the form of 

 angular, radiating, or branching masses. A. angulosa is one of 

 the deep-sea forms described by Mr. H. B. Brady from the 

 Challenger dredgings. It appears to have a very limited dis- 

 tribution in existing seas. The last-named authority states 

 that the figured specimens of his work " are all from station 

 78, east of Azores, from a depth of 1,000 fathoms, and except 

 for a single example found in one of the Porcupine dredgings 

 in the North Atlantic at 630 fathoms, this is the only locality 

 at which the variety has been collected." The specimens under 

 notice were found, I believe, at Waurn Ponds, near Geelong, 

 and correspond exactly with the subtriangular specimens 

 figured by Mr. Brady.

Mr. A. W. Waters, F.G-.S., has published two more valuable 

 articles on the fossil Bryozoa of Australia since our last notice 

 of his work in this department. In Quar. Jour. Geol. Soc, 

 Nov., 1884, he deals with the Cyclostomatous group, and 

 figures several new species from Aldiuga, the Mount Gi-ambier 

 beds, and from the Tertiaries of the other colonies. Prof. Tate 

 having sent a large series of Bryozoan remains to Mr. Waters, 

 the result of extensive work in the Aldinga and Murray Cliff 

 sections, and including a few from the Adelaide Government 

 bore, Mr. Waters has described them in loe. cit., Aug., 1885. 

 The collection furnishes no less than 73 species, " of which," 

 Mr. Waters states, " 46 are known living, bringing the number 

 of Australian fossil Bryozoa described up to 220, of which 

 just about half have been found living." The former article 

 is illustrated by two plates, and the latter by one. 



The full list of species as determined by Mr. Waters from 

 South Australian " Older Tertiary" material is as follows: — 



1. Cellaria malvinensis, Bush. 



2. " angustiloba, B. 



3. Membranipora aperta. Bush. 



4. " circularis, cVOrh, 



5. " ^ Savartii, Aud. 



6. " * radicifera, Hinchs. 



7. " rhynchota. Bush. 



8. " temporaria, spec. nov. 



9. " Flemingii, Bush.
