Chcetetes Helderhergice, C. sphcerica, Favosites Helderhergice, F. conica, F. ? 

 minima, Michelinia lenticularis, Striatopora Issa, and Streptelasma 

 {Petraia) stricta. The genus Palesdiara is proposed for certain Polyzoa 

 which may be parasitic or free, and which are composed of polygonal 

 cells with thin solid walls, and without septa or tabulae. The genus 

 Vermipora is proposed for certain Polyzoa composed of ramose branches 

 formed by the union of serpula-like tubes cemented upon each other, 

 and the apertures of which are directed upwards, and open on the side 

 of the branch. The tubes are without septa or tabulae. H. A. N.

lu this communication the author describes the following new 



species or varieties of Ooniatites from the Devonian rocks of North 



America: — G. complanatus, var. perlatus (Chemung group?); G. uni- 



lohatus (Hamilton group); G. (Clymenia?) Nundaia (Portage and 



Chemung groups) ; G. simulator (Chemung group) ; and G. Chemun- 



gensis, var. cequicostatus (Chemung group). • H. A. N.

 lished till 1874. The final paper, " Notes on some New or Im- 

 perfectly-known Forms amongst the Brachiopoda,'" &c., was 

 printed and circulated in 1871, and is not abstracted in the 

 present place.] 

 The authors describe and illustrate the following new species from 

 the Devonian deposits of Iowa, some of these deposits being of Corni- 

 ferous Limestone (Upper Heiderberg) age, others being apparently the 

 equivalent of the Hamilton Formation, and others being identified with 

 the Chemung group. The Protozoa are represented by Stromafopora 

 erratica, S. expansa, S. (Coenostroma) incrustans, S. (Ooenostroma) soli- 

 dula, and Caunopora planidata. The corals are represented by Fistu- 

 lipora occidens, Alveolites Pochfordensis, Cladopora prolijlca, C. magna, 

 and C. palmata, Zaphrentis solida, PacJiypliyllum Woodmani, P. soli- 

 tarium, Campophyllum nanum, Chonophyllum ellipticum, Acervularia 

 inwqualis, Smithia Johanni, S. multiradiata, CystipJiyllum mundulum, 

 Aulopora saxivada, and A. loiuensis. The species of Pachyphyllum 

 are the first of the genus recognized in America. It is noticeable also 

 that the occurrence of mural pores is now for the first time recognized 

 in Cladopora, which would apparently justify the view that Cladopora 

 is really founded upon ramose species of Favosites. The Polyzoa (?) 

 are represented by one form only, viz. Stomatopora (Alecto) alternata. 

 The new .Brachiopods are Crania famelica, Spirifera Orestes, S. sub- 

 varicosa, S. cyrtinaformis, Cryptonella Calvini, Strophopodonta Canace, 

 and S. hyhrida. Two species of Gasteropoda are described — Pleuroto- 

 maria Isaacsii and Naticopsis gigantea.
