FISH FAUNA OF THE GONODONT BED (BASAL GENESEE) AT EIGHTEEN-MILE 



CREEK, NEW YORK 



BY fv. HUSSAKOF AND W. L. BRYANT 



(Ahstract) 



The conodont bed is a thin layer of imimre limestoue at the base of the 

 Genesee at Eighteen-mile Creek, New York. Tt has a maximum thickness of 

 four or five inches, thins out in either direction, and in some sections is absent 

 altogether. It thus seems to occur in lenticular patches. Conodonts are ex- 

 tremely abundant in it, to which circumstance is due its name. 



Until a few years ago no vertebrate remains were known to occur in this 

 bed ; but an extensive and very remarkable fish fauna has since been obtained. 

 This includes sharks, Arthrodires, Ptyctodonts, Ichthyodorulites, Dipnoans, 

 and Ganoids. There are four or five new genera and about a d(jzen new spe- 

 cies in the materials. The remains are generally fragmeutal, but complete 

 dental elements and other plates have been collected. The assemblage consti- 

 tutes one of the most remarkable Devonic fish faunas known. It will be de- 

 scribed and fully illustrated by the authors in a catalogue of the fossil fishes 

 in the Museum of the Buffalo Society of Natural Science, now nearly ready 

 for press. 



Discussion by Messrs. Wieland and Burnett Smith.

FLORIDA 



BY E. H. SELLARDS 



(Ahstract) 



Two principal faunal horizons were considered, the Alachua clays and the 

 Peace Creek beds. The latter have been thought to be intercalated between 

 marine Pliocene strata, but the evidence for this is inconclusive, and there 

 appears to be no reason against regarding the fauna as Pleistocene. The 

 Alachua clays are probably Upper Miocene, 



The paper was discussed by Messrs. Osborn, Gidley, and Matthew.
