Wahl., Sphcerophthalmus alatus, and Agnostus pisiformis. There was 

 also a small Lingulella similar to that which characterizes the upper 

 flags of the St. John group, aucl an Orthis similar to Or this lenticularis 

 of Dalman. 



In discussing the evidence afforded by the smaller-eyed trilobites of 

 Division 1 of the St. John group, Mr. G. F. Matthew 1 speaks of their 

 bearing on the origin of the Cambrian fauna. He also gives a list of 

 fossils known to him at that date from Division 1 of the St. John series. 

 The total is thirty genera, sixty-five species, and twenty-one varieties, 

 the same as in the paper previously mentioned in the synopsis of the 

 fauna of the St. John group. 2 Mention is made by Mr. Matthew of ad. 

 ditional species from the St. John group in 1888. 3 In the measures on 

 the St. John River corresponding to those of Band B in Division 1 of 

 the St. John Basin, a calcareous organism that may be referred to Old- 

 ham ia has been found. It resembles 0. antiqua, but branches less freely. 

 In the same sandstone occurs an elegantly ornamented Lingulella (?) of 

 peculiar form. Mr. Matthew compares it with Lingula ? favosa of the 

 Eophyton sandstones of Sweden. In Division 2 of the St. John group 

 were found several genera of seaweeds, among which are two graceful 

 species related to Taonurus or Spiropliyton ; also fragments of bodies 

 of a small crustacean that is probably a Ilymenocaris. In a paper pub- 

 lished soon after on the u Classification of the Cambrian Eocks of Aca- 

 dia, 7 ' Mr. Matthews states 4 that the Lower Potsdam of Billings, or 

 Georgian of Mr. Walcott, is found in the island of Cape Breton, where 

 the fossils areBathyurus (sub-genus?), Orthisina, Orthis, and Eyollthes 

 princeps. Remarks upon the affinities of the characteristic genera of 

 the Georgian and other portions of the Cambrian fauna occur in this 

 paper. 



Mr. Matthew presented Part iv of his illustrations of the fauna of 

 the St. John group to the Royal Society of Canada in 1887. 5 The 

 first species described is the great Paradoxides regina, one of the 

 largest trilobites yet discovered in the Cambrian rocks. This is 

 followed by a description of "The smaller trilobites with eyes." An 

 undetermined species is referred to the genus Ellipsocephalus, and 

 Agraulosf wltitfieldianus is described with its variety compressa. The 

 subgenus Strenuella is proposed, with the species Strenuellat halliana 

 as its type. A discussion of the genus Liostracus of Angelin is 

 followed by descriptions of Liostracus tener Ilartt, L. ouangondianus 

 llartt, and varieties immarginata, aurora, gibba, and plana, and a
