No. 64. Evidently an error of determination or of locality, as no other 

 collection of this species had been made in Missouri, and I suspect Pech had 

 mistaken for this species either H. chrysophyllum Brid. or H. hispidulum Brid., 

 neither of which, though very common, are listed by him. Another fine species 

 of Hypnum, H. curvifolium Hedw., so common on rocky ground in Eastern 

 Missouri, and H. Patentiae Lindb., of similar situations and range, appear to 

 have been overlooked by Pech. 



No. 65. Evidently intended for Rhynchostegium serrulatum L. & J., and 

 very likely correct, as this species is common on the ground in woods throughout 

 the State. Another species of Rhynchostegium, R. deplanatum, Schimp., common 

 in similar situations, does not seem to have been collected by Pech. 



No. 66. Evidently intended for Pylaisia polyantha (Schreb.) Br. & Sch., 

 now known as Pylaisiella polyantha (Schreb.) Grout, but very doubtful, as this 

 is a species of the Northern and Eastern states, and no other specimens are 

 known from Missouri.

MOSSES, HEPATIGS, AND LICHENS OF THE QUARTZITE HILLS OF 

 THE KAMOURASKA FORMATION, QUEBEC, CANADA 



Fr. M.-Victorin 



In the counties of Montmagn^-, I'lslet, Kamouraska and Temiscouata, the 

 St. Lawrence lowland is broken by a few sharp elevations that can hardly fail to 

 attract the attention of the passing tourist on account of their very peculiar shape. 

 The rocks of this formation have been of late studied by Mr. John A. Dresser of 

 the Geological Survey^ and provisionally separated from the Sillery in which 

 they were included. 



The Kamouraska formation as it is now comm.only called, consists in a 

 series of detached hills which are seldom more than 300 feet high and a couple 

 of miles in length, and most of them are much smaller. In the ground plan they 

 are much flattened ellipses, the longer axes running in a northeasterly direction. 

 In structure they are sharply folded anticlines, slightly overturned towards the 

 northwest, giving a general dip to the southeast of about 75°. They are also 

 domed so as to give a pitch of 15° or 20° to the northeast and southwest near 

 the ends of many of the hills. 1 he course of the chief glaciation has been nearly 

 at right angles to the trend of these ridges, and the central parts of sorne of the 

 domes have been broken away by the ice, leaving the extreme ends of a hill pitch- 

 ing away from each other, sometimes separated by a drift covered interval. 

 The Gros Pelerin Island offers a good example of an ice-notched dome. 



The Kamouraska quartzite is fine, even-grained, light-colored, and weathers 

 to an almost pure white, very striking in the landscape. Quartz is usually the
