of the reissue seems also to have been private. The paper seems, 

 therefore, not to have been accessible to the public till 1874.] The 

 following species are described and illustrated from the Hudson-River 

 group of Ohio, Wisconsin, and Kentucky, mostly from the vicinity of 

 Cincinnati and Lebanon, Ohio : — Glyptocrinas Nealli, G. parvuSj Pote- 

 riocrinus (Dendrocrinus) caduceus, P. posticus, Heterocrinus constrictus^ 

 H. laxiis, H. juvenis, Heterocrinus '! (locrinus) Polyxo, H. exilis, Agela- 

 crinus ( Lepidodiscus) Cincinnatiensis, Roemcr, A. pileiis, A. verticillatus, 

 A. (Hemicf/stites) steUatus, Lichenocrinus Dt/erl, L. crateriformis. Crania 

 scabiosa, C. Loelia, Trematis mlllepunctata, T. pustulosa, Dalmania 

 breviceps, and Proetiis parviuscidus. From beds of Trenton Limestone 

 age the following fossils are described : — Gyclocystoides Salteri, G. ante- 

 ceptus, Grania Trentonensis, G. setiyera, and Pholidops Trentoneiisis.

Hall, Prof. James. Descriptions of new species of fossils from the 

 Hudson-lliver group in the vicinity of Cincinnati, Ohio. 24th 

 Ann. Rep. S. C. New York, pp. 225-232, pis. vii. & viii. [pub- 

 lished in advance in 1871 ; but its circulation appears to have 

 been private.] 

 The following species are described and figured in this paper : — 

 Leptobolus lepis, L. occidentalism L. insiynis, Lyrodesma Gincinnatiensis, 

 Tellinomya pectuncidoides, Fusispira ventricosa (Trenton), F. elonyatus 

 (Trenton), F. terebriformis, Gyrtolites Dyeri, Leperditia (Isochilina) 

 cylindrica, L. {IsocJidina') mlnutissima, Beyrichia tumifrons, and B. 

 ocidifera. The genus Leptobolus is proposed for certain minute Lingu- 

 loid shells which occur in the Hudson-River group and Utica Slates. 

 The ventral valve has a distinct area and pedicel-groove, with an 

 elevated subquadrate muscular area; the dorsal valve has slightly 

 elevated trifid muscular impressions. The genus Fasispira is proposed 

 for certain Gasteropods which have the general form of Fusus and 

 Subulites, but differ from the former in the much less twisted colu- 

 mella, and from the latter in not being truncate at the base of the colu- 

 mella, and in being destitute of a deep anterior notch. The species of 

 the genus are confined to the Trenton and Hudson-River formations.
