rilepas occur in both the 1892 and 1894 collections. This species is 



identical with another found in a lot of Newfoundland fossils, labelled 



" Port-aux-Choix," and collected by Mr. Richardson. The species is 



very closely related to one of the forms described by Nicholson and 

 Etheridge from the Girvan district {loc. cit. ante.) 



Entomostraca. 



26. Primitia sp. No. 1. 



27. " sp. No. 2. 



28. Isochilina sp. indt. 



Trilobita. 



29. Ampyx, cf. A. normalis, Bill., or its near ally. A. rostratus, 

 Sars. The latter species occurs in the rocks of the Girvan succession, 

 and this is abundant in the rocks of Mountain Hill. It was collected 

 in 1877, in 1892 and 1894. 



30. Amphion 1 sp. indt. An imperfectly preserved or obscure 

 pygidium of a trilobite, which is most probably referable to this 

 genus. 



31. Bathyurus, sp. No. 1. 



32. " sp. No. 2. 



33. Dolithometopus ? sp. or Symphysurus, sp. 



34. Remopleurides, sp. No. r. Apparently new. Differs some- 

 what from D. Schlothimi, Billings, and from D. Canadensis and D. 

 affinis, already described from Canadian rocks. It belongs to the typical 

 or smooth form, of which the last two mentioned are types. 



The Mountain Hill specimens, which are tolerably abundant, are 

 not unlike in general outline to Remopleurides Barrandii, Nicholson 

 and Etheridge Jr., good specimens of the cephalon of this species occur 

 in both the 1892 and 1894 collections. 



35. Remop/eiirides, sp. No. 2. Smaller form. 



36. Dalmanites callicephalus ? Green. 



37. Calymene senaria, Conrad. ( = C. tuberculata, of European 

 authors, also C, Blumenbackii.) 



38. Asaphus canalis, Conrad.
