PALiEOPHYCUS FUNICULUS. (N. Sp.) 



Description. — This species consists of long, slender, cylindrical wire- 

 like stems, about IJ lines in thickness, gently curved and sparsely scat- 

 tered about the surface of the strata. Sometimes they are found in 

 considerable numbers lying across each other, but never in such dense 

 reticulating layers as those formed by P. Beverleyensis and P. Beauhar- 

 noisensis. Single stems one foot or more are often seen without any others 

 near them, and being, when not distorted by pressure, very nearly cylin- 

 drical, they somewhat resemble a round, smooth crinoidal column. 



Locality and Formation. — Edwardstown, near Norton's Creek Mill, in 

 the County of Napierville. Calciferous formation. It also occurs near 

 L'Orignal, in the County of Prescott, in loose slabs.

PALiEOPHYCUS OBSCUKUS. (N. Sp.) 



Description. — This species consists of cylindrical, rod-like stems, usually 

 from i to I of an inch in thickness. They are usually straight, and found 

 in broken pieces from 3 to 12 inches in length, being most common in the 

 thin beds of shale between the strata of hmestone. They are sometimes 

 more or less crooked, but never, so far as I have observed, gracefully 

 curved. They very much resemble in size and form P. tubularis (Hall), 

 Pal. N.Y., vol. i., pi. 2, fig. 1, and may possibly be the same species. 

 At present I think them difierent, and propose to name them as above, 

 provisionally. 



Locality and Formation. — City of Ottawa. In the Trenton limestone. 



Collectors. — J. Richardson, E. Billings. 



Pal^ophycus Beauhaknoisensis. (N. sp.) 



Description. — This species is evidently alUed to P. Beverleyensis, 

 differing therefrom principally in the greater size and more rigid aspect of 

 the stems. These vary in thickness from 1 to 4 lines, but the most 

 common size is from 2 to 3 lines. They are either straight or slightly 

 curved, nearly cylindrical, somewhat angular, often with one or more deep 

 longitudinal grooves. They cover large surfaces of the rock, crossing 

 each other at all angles. Some of the stems can be traced to a length of 

 two feet. They often appear to be somewhat flattened, and show some 

 indications of branching at an acute angle. 



Locality and Formation. — Beauharnois. Calciferous sandrock. 



Collectors. — Sir W. E. Logan, J. Richardson.
