 lappacea [Syn. Danthonia lappacea Lindl.,] forwarded to him by 

 Mr. N. Turnbull, Noorama, Cunnamulla, Queensland. The ex- 

 hibitor first drew public attention to this grass as producing a 

 fairly large grain, like small wheat, at a meeting of the Austra-

Dr. H. G. Chapman reported some results of the breeding of 

 guinea-pigs by his wife and himself. Attention had been paid 

 to the colour of the hairs, length of the hairs and arrangement

Dr. Petrie showed, on behalf of himself and Dr. Chapman, a

 mentioned under the latter name in Froggatt's Entomology, and 

 in other publications.
