Gorgonia repisteria (Goldfuss), p. 50, pi. xxiv, 3; from Schoharie, Ne\v York. 

 Gorgonia aiiticorum n. sp., p. 50, pi. xxiv, 1; from Lake Huron. 

 Gorgonia siluriana n. sp., p. 50; from Lake Huron. 

 Eschara scalpellum (Murchison), p. 50; from Isles Mantoulinen. 

 The descriptions are so meager that no one has succeeded in identifying any of 

 these forms. 



1846. 



Dana, James D. Zoophytes. (Wilkes's U. S. Exploring Expedition, 



Vlll, Philadelphia, 1816, 710 pp., 61 plates in atlas.) 



This work contains a description of Lonsdale's genus Stenopora and of a new genus 

 Constellaria (p. 537), both being considered corals by the author. The latter was 

 established for a species named Ceriopora constellata on plates of "Western Fossils by 

 Van Cleve. The form was later erroneously identified as the »Stellipora antheloidea 

 of Hall and became currently known as Constellaria antheloidea, Dana's name Con- 

 stellaria Having replaced Hall's Stellipora.

338 pp., 98 pis. 



About twenty new species of bryozoa from the Trenton and Chazy periods are 

 described in this greatest of early works on American paleontology. The new genera 

 established are Stictopora, Escharopora, and Stellipora. As is usual with the early 

 work on fossil bryozoa, both the descriptions and the figures leave much to be 

 desired. Even to-day several of the species are not satisfactorily recognized, while 

 the number and diversity of distinguishable forms referred to ' ' Chsetetes lycoper- 

 don" is distressing to the modern student.

Orbigny, Alcide d'. Prodrome de Paleontologie, Tome I. Paris, 1850. 



In this extensive catalogue the following American paleozoic bryozoa are listed: 

 Ptilotlictya cruciformis, Ptilodictyapavonia, Sulcopora f enestrata, Subretepora reticu- 

 lata, Enallopora perantiqua, Constellaria antheloidea, and the new genus Monticuli- 

 pora with the species mammulata, ramosa, frondosa, and filiasa. Most of the names 

 are accompanied by quite inadequate descriptive remarks, and the validity of those 

 now recognized depends upon the work of subsequent authors. Sulcopora, Subrete- 

 pora, and Enallopora are new generic terms founded not upon the fossils themselves, 

 but upon Hall's incorrect descriptions and figures of 8tictopora f enestrata, Intricaria 

 reticulata and Gorgonia perantiqua, respectively. Resting, therefore, upon fi"*^'Mons 

 characters, these names have deservedly failed to gain recognition. 



1851. 



Hall, James. Description of new or rare species of fossils from the 

 Paleozoic series, (Foster and Whitney's Report on the Geology 

 of the Lake Superior Land District, 1851. Bryozoa, pp. 206-208, 



pis. xxiv, XXV.) 

 Among the descriptions occur three of bryozoa: Phsenopora multipora, Clathro- 

 pora fiabellata n. sp., and Chaetetes lycoperdon Say.
