\. A. IN VERTEBRATE TAL^'EONTOLOGY. 717 



I'wLMity six new species of invertebrates are described in this paper, 

 which is divided under the following beads, viz : 



(1) BibHography of the formations here discussed, viz, the Genesee, 

 the Naples, the Portage, and the High Point Chemung rocks of JSTew 

 York. 



(13) The Petrographic and Paloeontologic Oharacjters of the Genesee 

 Beds. 



(3) Review of the Fauna and Flora of the Genesee Shales. Here the 

 following new species are described : Goniatites nodifcr, Bcyrichia Da- 

 (Jan., Goniatites astarte, Orthoceras Stehos, 0. Mephisto, 0. Asmodeus, 

 Platyosfoma Belial, Loxonema (?) Moloch, Modiomorpha {!) Ghemos, ^piri- 

 /era Belphegor, S. Pluto, Leiorynchus (!) Hecate. 



(4) The Petrographic and Palseontologic Characters of the Naples 

 Beds. 



(5) Review of the Fauna and Flora of the Naples Beds. Here the 

 following new species are described : Geratiocaris simplex, G. Beecheri, 

 Echinocaris Whitjieldi, Goniatites Lutheri, Grtiioceras aciculoides, 0. On- 

 tario, 0. filosum, Bellerophon incisus, Trochus {Palmotrochus) prcecursor, 

 Platyostoma (?) minutissimtim, Loxonema N'oe, Hyolitlies Napolis, Lingula 

 triquetra, Aulopora annectens. 



(G) The Petrographic and Palseontologic Characters of the Portage 

 Beds. 



(7) A List of the Fossils occurring in the Genesee, Naples, and Portage 

 Beds of Ontario County, with the names of species heretofore identified 

 from the horizons elsewhere in the State of New York, but not as yet 

 known within this district. From these tables he concludes that the 

 Naples shales have no such palseontologic relation to the rocks of the 

 Chemung period as to justify the union of them with these rocks; that 

 their fauna and flora is more closely allied to those of the Hamilton 

 sliales, and that therefore these beds are to be regarded either as con- 

 stituting the uppermost member of the Hamilton jieriod or, together 

 with the Genesee shales, representing a distinct geological epoch. The 

 more probable con(;lusion is that these two groups of strata represent 

 the epoch of the lower Uppiir-Devouian in Western New York. 



(8) Fauna of Chemung Beds at High Point. It is unfortunate that 

 six of the new species described are not illustrated in any manner.

(I) Remarks on certain criticisms by Prof. James Hall, of All)any, in 

 the preface to volume G7 of the Pennsylvania reports, on the palaeonto- 

 logical portion of the work in tlie volume. Mr. Clayi)ole states that 

 there is no doubt that in Perry County spirifers, unbroken and with both 

 valves in contact, are found about 1,000 feet above red sandstone beds 

 holding the scales of Holoptyckius or Bothriolepis or both. (2) The au- 

 thor states that Spirifera disjuncta, 8. mesocostaUs, S. mesostrialis, though 

 evidently characterizing, i)robably, in some places, by their abundance,
