Lycoperdon rubro-flavum, L. sigillatum, L. rima-spinosum, T.. taba- 
cinum (the last by J, B. Ellis) and Geaster turbinatus are other 
new species of Gasteromycetes. Lists of ferns, mosses, lichens, 
algze and parasitic fungi complete this very interesting bulletin. 
—Part 11 of the Catalogue of Canadian Plants, by John Ma- 
coun, is a thick pamphlet of about 200 pages, devoted to the 
Gamopetalz. Curiously the number of species in this part (908) 
is almost exactly the same as in the previous one, viz., 907. There 
is a great deal of exceedingly valuable information given upon 
the geographical range of species, and also much in the way of 
notes upon habitats. Dr. Gray’s memorial of George Bentham 
in the American Fournal of Science for February, contains one of 
the fullest accounts of the very full life of the venerable botanist, 
whose death the world still mourns. “ His life was a perfect and 
precious example, much needed in this age, of persevering and 
thorough devotion to science while unconstrained as well as un- 
trammeled by professional duty or necessity. For those endowed 
with leisure, to ‘ live laborious days’ in her service, is not a com- 
mon achievement.”——Nos. 1 and 2 of the Yournal of Mycology 
have been received, and we can only say at this time that the 
matter is, in the main, good, but that the editor has not yet suc- 
ceeded in getting from his printers as good work as is desirable. 
This, however, will doubtless be improved in the future.

Generic Position oF POLYDESMUS OCELLATUS.—In a letter to 
Professor Packard the undersigned writes as follows : 
In the American NATURALIST, April, 1883, you have published 
per on “a new species of Polydesmus with eyes,” which you 
have called Polydesmus ocellatus. As can be seen from your 
description given there, the new myriopod must be a species of 
the genus Craspedosoma Leach (Transac. Linn. Society, Vol. X1, 
p. 380, printed 1815), and not of the genus Polydesmus Latr. ; 
for the latter genus is always characterized by the want of eyes 
and by the number of segments being twenty, whereas the for- 
mer genus is characterized by oculi composed by multiseriated 
ocelli and by the number of segments being thirty or, in younger 
specimens, less, from twenty-seven to twenty-nine. 
In consequence of the necessity of ranging your species in 
another genus, all the members of which are provided with eyes, 
the specific name ocellatus should be removed and another intro- 
duced instead of it. I propose the name Craspedosoma pack- 
_ As I have reason to suppose, you are probably not in posses- 
sion of Dr. Fr. Meinert’s paper on the Chilognatha of Denmark
