never saw it distinctly. And although the genus is classified by him 

 among the Cystideans, he says, " La structure de ce corps ^nigmatique 

 est en g^n^ral trop peu connue, pour lui assigne la place qu'il doit occuper 

 parmi les corps fossiles."* 



I do not assert positively that Pasceolus is not a Cystidean, but think 

 the evidence we possess is scarcely sufficient to authorize us to place it in 

 that group. Sphceronites tesselatus (Phillips) appears to be closely allied, 

 but is now considered by Mr. Pengelly (see Geologist), vol. iv,) to be a 

 sponge. 



The following are the species of Pasceolus collected in Anticosti. 



P. HallIj. B. — Gamache Bay ; Div. 1, A. G. 



P. GREGARius, n. sp. This species is smaller than P. Halli, and is 

 always globular or nearly so. The individuals are from 6 to 12 lines in 

 diameter, usually about 9 lines ; there are from three to four plates ? in the 

 width of 2 lines. Reef Point ; Div. 1, A. G. J. Richardson. There arethe 

 remains of about fifty in a small slab of limestone 5 inches in width and 

 7 inches in length. 



P. iNTERMEDius, n. sp. — Globular ; about 12 lines in diameter ; four 

 concave plates ? in the width of 3 lines. Three miles west of Jupiter 

 River ; Div. 2, A. G. J- Richardson. 



ADDITIONAL SPECIES FROM THE HUDSON RIVER GROUP. 



Genus, Licrophycus, Billings. 



L. FORMOSUS. — The specimen on which this species is founded has the 

 main stem near the root (the latter not preserved) seven lines in thick- 

 ness. In a length of three inches it is divided into eleven branches from 

 three to four lines in thickness each. These are subdivided three or four 

 times, the branches coming off at an acute angle. Several of the branches 

 curve downwards. They appear to be, in some places, obscurely angular. 

 English Head ; H. R. T. C. Weston. 



L. VAGANS. — Branches long, slender, cylindrical and somewhat crooked. 

 A specimen springing from a single root is spread out to the width of nine 

 inches ; length six inches. The branches are from two to three lines in 

 thickness. Near the West-end lighthouse, H. R. T. C. Weston. 



L. ROBUSTUS. — Branches about one inch in thickness and from six to
