description of the Silurian fish, Diplaspis Acadica, which was described 

 by Mr. Matthew for the first time in Vol. II of the Canadian Record of 

 Science, p. 251. The description of the related genera and species, as 

 well as the geological horizon from which the species comes, are next 

 gi'ven. Then follows the description of a new species of Ceratiocaris 

 (McCoy), or Phinocaris (Clarke), viz., C. yusillus, obtained at the same 

 locality as the Diplaspis, viz., Cunningham Brook, near Westfield Sta- 

 tion, N. B. With these there was also found the type of a new genus 

 of crustacean allied to certain forms of Packard's sub-order Synxi- 

 phosura, and for which Mr. Matthew proposes the generic designation 

 Bunodella, and describes the species as B. horrida. 



The second part of the paper contains descriptions of the Devonian 

 forms, and includes: 1, One orthopterous insect ; 2, a chitinous grub ; 

 and, 3, a new crustacean. The wing of the orthopterous insect upon 

 which the genus and species are founded, was found in Plant bed No. 2 

 of the Cordaite shales of the Lower Devonian series at Lancaster, N.B., 

 where Prof. Hartt discovered Xenoneura antiquorum years ago. It goes 

 under the name of Geroneura Wilsoni. The grub is described as 

 Archceoscolex corneus, and is " the first example of the body of an insect 

 recognised among the Devonian shales at St. John." Eurypterella ornata 

 is the name applied to a supposed crustacean of small size from the same 

 beds as Geroneura Wilsoni, and was found by Mr. W. J, Wilson, who 

 collected nearly all the material from which the above species were de- 

 scribed and figured. 



The following is a resumS of the species described : — 

 Silurian. Devonian.
