70 DR. 8. O. LINDBERG’S BRYOLOGICAL NOTES. 
It is very like H. (Rhynchost.) algierianum, but is instantly di- 
stinguished by its scabrous seta, and from H. Teesdalei, Sm., by 
the form and areolation ofthe leaves, the thinner and narrower 
nerve, the areolation of the capsule, &c. 
The very interesting Habrodon Notarisii, Schimp., has lately 
been found growing both in Great Britain and Norway. It was 
previously known only from Italy and the Pyrenees ; but I do not 
think it constitutes a proper genus. Its nearest ally is the North- 
American Clasmatodon parvulus (Hamp.), Sull. (CL pusillus, 
H. W.), from which I find it impossible to distinguish it generi- 
cally. I consider the European species to be also a Clasmatodon, 
among the forms of which I should also place the very rare Ani- 
sodon Bertrami, Schimp. With regard to Dubyella italica, Schimp.; 
I do not think it a sufficiently distinct genus; judging from the 
excellent figures and description in * Musci Novi Europæi, it must 
be a .Leskea. 
I now give the synonyms of the three species of Clasmatodon, 
so as to render the history of the genus more complete.
