H. scorpioides, L. Bog near Malham Tarn, J. Nowell. I believe that 

 " Beamsley rocks," cited as a stationln the " Tlora of the West Eiding " 

 with my name, is erroneous. The moss which I found there was 

 Limnobium ( Hypnum) ocliraceum. A[useful microscopical character of 

 H. scorpioides, which is not, so far as I know, mentioned by any author 

 is found in the teeth of the peristome. Between the large teeth two 

 secondary unicellular teeth are exserted, both of which are much narrower 

 than the primary ones, but nearly as long.

According to the classification of modern geologists, all the fossiliferous 

 rocks that compose the known portion of the earth's surface, are arranged 

 under four great divisions — the Primary, Secondary, Tertiary, and Quaternary. 

 Each of these great divisions is supposed to refer to successive periods in the 

 earth's history, during which certain animals and plants peculiar to their 

 respective eras have existed, living when different kinds of sediments were 

 deposited which now form the different strata. The Primary rocks are the 

 most ancient formations. These include the Permian, Carboniferious, Devo- 

 nian, and Silurian. 'Not one of this series of rocks is found in this neigh- 

 bourhood. The Secondary rocks are well represented in this locality. This
