Spencer, Dr. A. E. Trueman, Dr. F. 8. Watts) appointed to excavate 
critical sections in the Paleozoic rocks of England and Wales. 
Aw expedition was arranged by the Geological Department of the National Museum 
of Wales in June 1929 with the object of undertaking intensive collecting at certain 
important horizons on Ramsey Island. 
Owing to the difficulty often experienced in crossing from the mainland, the party, 
consisting of members of the museum staff and Dr. Pringle, together with three 
labourers, camped on the island. 
Special attention was paid to beds near the base of the Ordovician and in the upper 
part of the Cambrian, and a fairly extensive collection of fossils was obtained from a 
number of important localities that were indicated by Dr. Pringle. 
One of the special objects of the visit was to rediscover the horizon from which 
certain earlier workers had obtained starfish remains, and after considerable search 
such a horizon was located at the northern end of the island and some echinodermatous 
material obtained. The remainder of the material consists principally of trilobites 
_ and brachiopods. 
_ Owing to building operations at the Cardiff Museum, detailed work upon the 
collection has not been possible this year, but the material has been labelled in readi- 
ness for such work. 
The specimens upon which asteroids or other echinoderms were present have been 
submitted to Dr. W. K. Spencer, who writes as follows :—‘ The material you sent me 
contained a block and counterpart (29.308 Cr. 35 and Cr. 26. Loc. 3), which 
showed the moulds of three specimens of a new Asterazoan. It is akin to Uranaster. 
a species of which Uranaster ramseyensis was the sole form known previously to 
these rocks. Although akin to the previously known species, it has such distinctive 
differences that I may have to put it into a new genus. 
* Obviously you are on the track of a very old fauna, older than that known from 
Dyl of Bohemia. Only one Asterozoan is known earlier, and that is an undescribed 
genus Cambraster, Jaekel, from the Middle Cambrian of France. 
* There were a fair number of other Echinoderm remains, and several looked to 
me well preserved. They look as if they would be well worth the attention of 
_ appropriate specialists.’

Treasurers; Prof. J. Srantey Garpiner and Mr. F. A. Ports, 
Secretaries; Prof. Sir Epceworrn Davin, Prof. W. T. Gorpoy, 
Prof. A. C. Sewarp and Dr. H. H. Tuomas, from Section C; Mr. E.

Hinks, from Section E; Prof. F. K. Frirscu, Dr. Margery Knicur, 
Prof. A. C. Sewarp, from Section K) appointed to organise an expedi- 
tion to investigate the Biology, Geology and Geography of the Australian 
Great Barrier Reef. 
Ar the time of the last meeting of the British Association all the British members 
of the expedition had returned to England anda good deal of progress had been made 
into the working out of the results. It was, however, decided to delay the presentation 
of the final report till this year so that the complete arrangements might be recorded. 
One meeting of the Committee has been held during the year.
