A plea for the classification of Salter and Hicks," 1 a comparison of the 

 genera of the different horizons of the Cambrian is made. 



In tbe full paper on the Cambrian organisms of Acadia, published in 

 1890, Mr. Matthew describes the stratigraphic position of the fauna that 

 he considers beneath the Paradoxides beds, and compares it with the 

 lower Cambrian fauna of Sweden and Russia. The new genera and 

 species described are: 2 



Pbycoidella, n. g.,p. 144. 



Phycoidella stichidifera n. sp., p. 144. 



Palaeocborda setacea n. sp., p. 145. 



Hydrocytinm (?) silicnla n.sp., p. 146. 



Micropliycus n. g., p. 146. 



Mierophycus catenatus n. sp., p. 146. m 



Monad ites n. g., p. 147. 



Monadites globnlosus n. sp., p. 147. 



Monadites pyriformis n. sp., p. 147. 



Monadites urceiformis n. sp., p. 147. 



Radiolarites n. g M p. 148. 



Eadiolarites ovalis n. sp., p. 148. 



Plocoscyphia (?) perantiqna n. sp., p. 148. 



Astrocladia(?) elongata n. sp., p. 148. 



Astrocladia (?) elegans n. sp., p. 149. m 



Astrocladia (?) virgnloides n. sp., p. 149. 



Dichoplectella n. g., p. 149. 



Dicboplectella irregularis u. sp., p. 149. 



Hyalostelia minima n. sp., p. 150. 



Obolus (?) major n. sp., p. 155. 



Lingulella martinensis n. sp., p. 155. 



Leperditia ventricosa n. sp., p. 159. 



Leperditia steadi n. sp., p. 160. 



He also describes and illustrates : 



Bnthotrcpbis antiqua Brongn., p. 144. 

 Platysolenites antiquissimus Eichw., p. 150. 

 Obolns pnlcber Matth., p. 151. 

 Volbortbella tenuis Scbmidt, p. 156. 

 Psammicbnites gigas Torrell, p. 157. 

 Arenicolites lyelli Torrell, var. minor, p. 159. 



In a note at the close of the descriptions it is stated that he has 

 learned that a suggestion made by him in reference to Olenellus Icjerulfi 

 has met with acceptance from a number of naturalists and the generic 

 name Holmia is proposed for Olenellus kjerulfi. 3 Mention is made of the 

 relations of the genera Olenellus, Olenoides, and Mesonacis. 



In his fifth contribution to the illustrations of the fauna of the St. 

 John group Mr. G-. F. Matthew describes the following new genera and 

 species: 4 Platyceras aperta, n. sp., p. 132, Agraulos (?) holocephalus, n. 

 sp., p. 138, Medusichnites, n. gen., p. 143, with five varieties, Lingu-
