1. '* Notice of three New Species of Fossil Shells from the Devonian of 

 Ohio." These are LeiorTiynclms Newherryi, Naticopsis cretacea, and 

 Porcellia JSciota — the first from the Chemung group, the last two from 

 the Upper Helderberg Limestone. Palceoneilo imralMa is also de- 

 scribed as a new species from the Waverley Limestone of Ohio. 



2. " Notice of Two New Species of Fossil Shells from the Potsdam 

 Sandstone of New York." The genus Palceacmcea is proposed for a 

 small Patelloid shell, more or less allied to Metoptoma, but wanting the 

 truncated anterior margin of this genus ; and the single species P. ty- 

 pica is described. A new species of Hyolithes is also described (H. 

 yibbosKs). 3. " Supplement." Describes two new species of Trematis 

 {T . punctostinata and T. inidis), both from hydraulic limestones of the 

 age of the Trenton Limestone at Clifton, Tennessee. Both are figured.

 Species of Fossils from the vicinity of Louisville, Kentucky, and 

 the Falls of the Ohio. 24th Ann. Rep. S. C. N. York, pp. 181- 

 200 a. [Dated 1872, but apparently published in 1874.] 

 Contains descriptions, without figures, of the following new species, 

 from beds of Niagara-Limestone (U. Silurian) age from Louisville and 

 the Falls of the Ohio : — Dictyoiiema pergracilis, Orihis nisis, 0. rugce- 

 plicata^ Spirifera rostellicm, Pentamems Kiiappi, P. I^ysius, Murchisonia 

 petila (M. Silurian), Euomphalus {Cycloiuma) rugoelineatd^ and Ulcunus 

 coimigenis. The following new species and varieties are described from 

 the Devonian of Kentucky and Indiana: — Crania Bordeni, Aviculo- 

 pecten cmssicostatus, Cardiopsis crassicosta, Lucina {Paracyclas) elliptica, 

 var." occidentalism Cypricardinia injlata, var. suhcBquivalvis, Cypri- 

 cardinia'? cylindnca, Yoldia? valvidus, Nucida niotica, Nucula neda 

 Tellinomya subnasuta, Ptyclwdesma Knappiana, PolypJiemopsis Louis- 

 villcp^ Loxonema hydraidica, Troclionema emacerata, T. rectilaiem, T. 

 Yandellana, PUurotomaria Estella [not Murchisonia Estella, Bill.], P. 

 imitator^ and Bucania Devonica. The new genus Ptycliodesma is pro- 

 posed for certain modioloid bivalves, with equally convex valves, the 

 hinge *' with a wide ligamental area, the sides of which are sharply 

 grooved in parallel lines, caused by the successive growth of the liga- 

 ment, as in Pectuncidus.^' A list of fossils from the Fall^ of Ohio, the 

 vicinity of JefFersonville, Indiana, and the neighbourhood of Louisville, 

 Kentucky, is given, but only includes the Crinoidea, Brachiopoda, 

 Lamellibrancliiataj Gasteropoda, Cephcdopoda, and Tnlohita. Finally 

 a supplementary note describes as new, under the name of Pentamemis 

 nucleus, a small Brachiopod from the Clinton group of Louisville, 

 Kentucky, which had previously been cited as P. galeatus. H. A. N.

 of Illinois. Amer. Journ. scr. 3, vol. vii. pp. 219-223. 



Arthrolycosa antiqua is described as n. gen. and sp. from the lower 

 part of the true Coal Measures. The palpus seems chelate, but the 

 state of preservation makes this doubtful j there is a pit on the cepha-
