plants having the cut of Grevillca are 

 currently referred to Lomatia, but they 

 might as well be placed in the former 

 genus. This case is of unusual interest 

 because the Proteacete are today south- 

 ern plants, scattered through the coun- 

 tries of the southern hemisphere, where 

 they lead naturalists to imagine land 

 bridges across which they might have 

 come. Proof that they once abounded 

 in the north temperate zone puts an 

 entirely new face on these speculations. 



Among the smaller plants at Florissant 

 are roses, including a well-preserved rose- 

 bud, ferns, grasses, and even fungi and 

 mosses. A fruiting moss which we found 

 was transmitted to Mrs. N. L. Britton, 

 and is now at the New York Botanical 

 Garden. A small liverwort, also sent 

 to the New York Botanical Garden, still 

 awaits description. 



The weak point in the Florissant col- 

 lection, so far, lies in the inadequate 

 representation of organisms other than 

 plants and insects. Scudder described 

 many spiders, but they were mostly 

 poorly preserved. Other spiders are 

 now in the hands of Dr. Alexander 

 Petrunkevitch for description. A single 

 millipede was published by the writer, 



and a specimen was handed to IVIr. R. W. 

 Miner of the American Museum for 

 description, but has not yet been pub- 

 lished. No centipedes have been found, 

 and it is extraordinary that a single 

 ostracod represents the Crustacea. The 

 mollusks number seven, two only being 

 land snails. There are ten fishes, in- 

 cluding an extinct genus of especial 

 interest. Two birds have been de- 

 scribed, and another is in the possession 

 of Dr. J. E. Cutler of Denver University, 

 and will shortly be made known. Feath- 

 ers are quite common. 



The only trace of Florissant mammals, 

 as yet, consists of some minute and frag- 

 mentary teeth. No reptile or amphibian 

 has been seen, although we have an 

 object which may possibly be a turtle's 

 flattened egg. A general summary of the 

 fauna was published in the American 

 Journal of Science, 1913, (p. 498), but 

 rather numerous additions have since 

 been made, and about sixty species of 

 insects (described by Wickham and the 

 writer), and several plants (described 

 by Knowlton) await publication. A 

 summary of the flora was given in Bulle- 

 tin Amer. Mus. Nat Hist., Vol. XXIV, 

 Februarv, 1908.
