POLYZOA. 



Genus Ptilodictya, Lonsdale. 



P. fragilis, n. sp. — Polyzoary consisting of narrow ligulate, two edged 

 branching fronds with the cellular surfaces gently and uniformly convex. 

 Cells ovate, their length rather more than one-half greater than their 

 width, surrounded with an obscurely elevated margin, seven or eight in 

 the length of one line and ten or twelve in the same space in width. 

 On each side there are two or three rows of oblique cells. Those which 

 occupy the middle of the frond are arranged in straight longitudinal rows. 

 There is a distinctly elevated line between each two rows The propor- 

 tional length and width of the cells appears to be somewhat variable. 

 The fronds, examined are from two-thirds to one line in width. Occurs 

 at Charleton Point ; H. R. Also at Junction Cliff; Div. 1, A. G.

P. nitidula, n. sp. — Polyzoary consisting of narrow, thin, ligulate 

 branching fronds, which are sharp-edged and very slightly convex on the 

 sides. Cells small, ovate, from seven to eight in the length of one line 

 and from ten to twelve in the same space in width, arranged in straight 

 longitudinal rows, width of specimens aboat one line. This species differs 

 from P. fragilis in not having the obUque cells at the edges of the fronds.

P. CANADENSIS, n. sp. — Polyzoary a single elongated frond, gradually 

 expanding in width from an acute point to six lines in a length of three 

 and a-half inches. Cells oblong ovate, six or seven in the length of one
