but we do not find any notice of the plant in his published narrative, although 
it contains many botanical notes. De la Pylaio was no donbt the first to col- 
lect the plant in Newfoundland, since, though it is not inhia herbarium. Prof. 
Ernnet informs us that it is mentioned in his MS, notes. We now have cer- 
tain knowledge of localities of heather in Massachusetts, in Cape Breton (sec 
ante, page 29), and in Newfoundland ; to which may be added Giesecke's tes- 
timony that it occurs in Greenland. (' Canadian Natiu-alist/ 1864, p. 459.)

Museum, but Calluna vulgaris^ mentioned in his list, is unfortunately not

Handbook of British Waterweeds or Algm. By Dr. John Edivard Gray,

It is nearly half a centiu^ since S. F. Gray ptiblished his * Natural 
Arrangements of British Plants/ and to this important work — the 
first to apply the natural system to our British Elora — Dr. Gray 
largely contributed. Since then, his life has been devoted to zoo- 
logy, and the number and value of the papers which, during this long 
period, have been pid)lished by him, are unexampled, we believe, by 
any other zoologist. He has again returned, to some extent, to his 
first love, and induced by the very extensive herbarium of British 
Algre which Mrs. Gniy possesses, he has lately, during the spare 
hours of an active life, prepared a valuable little manual of this class 
of plants. It must have been evident to our readers, that he has 
been euf^aged in such work, from the papers he has occasionally pub- 
lished in this Journal, on new Algse. The little volume will form a 
useful manual for the shore. The genera, amounting to 295, are 
carefully described, as are also the species in all the larger, Algpe, 
but lists only are given of the miimte and microscopic forms. In all 
cases, however, the species are arranged according to their affinities, and 
eacli genus is' divided into two or more sections, in proportion to the 
number of species it contains. This is an important feature in the 
volume, and one that will make even the lists of specific names it con- 
taius convenient in fichl diaj^nosls. It is to be regretted that the autho-

rities are omitted in a large proportion of the volume. This makes it
