assurde. Afin qu’on n’a plus a y toucher, je joins a l’exemplaire un 
croquis exact des sporanges, dont la forme est fort diffdrente de celle 
que Harvey a repr^senffie. Autant qu’il est permis d’en juger, d’aprbs 
un £chantillon incomplet et qu’on ne veut pas risquer de detruire, je 
rapporte X Ectocarpus fenestratus a l’espece qu’on nomme aujourd’hui 
E. Lebelii ; selon toute apparence, l’^chantillon est un exemplaire 
a antheridies, beaucoup plus d^veloppe que d’habitude. Quelques 
espbces voisines, telles que les E pusillus et insignis , pr^sentent par- 
fois un developpement semblable. Done, grace a vous, voici une

TYPE-SPECIMENS OE MRS. GRIFFITHS.— In the introduc- 
tion to ‘ A Revised List of the British Marine Algae/ by Messrs. Holmes 
and Batters, the authors remark 1 : ‘ It may be useful to state that in the 
course of our investigations we have found that the type-specimens of 
the following authors are deposited in the herein-stated herbaria ’ : — 
Then follows a list, in which I find 1 Mrs. Griffiths, Linnean Society, 
London/ This seems to me to need a word of comment. 
In the ‘ Report on the Progress and Condition of the Royal 
Gardens at Kew’ for the year 1862 I find, amongst the additions 
to the Herbarium 
‘ The unrivalled collection of British Seaweeds , formed during 
a long life devoted to that order of Plants, by Mrs. Griffiths, of 
Torquay. Presented by Miss Burdett-Coutts/ 
I believe that this herbarium was very extensive, and that there 
were vast series of specimens representing each species. Mrs. J. E. 
Gray was about this time in the habit of residing at Kew during part 
of every summer. Sir William Hooker entrusted to her the task of 
selecting a series of specimens which would represent Mrs. Griffiths' 
types ; these at the present moment are undoubtedly preserved in the 
Kew Herbarium. And the fact is well known to critical algologists, 
for Dr. Bornet, writing to me recently, mentions incidentally : — 
‘ L’herbier de M me Griffiths et celui de Berkeley sont conserves au 
Musee de Kew/ 
As I have said, the herbarium was extensive, and there were vast 
quantities of duplicates, such as a private collector might preserve for 
some purpose or other, but which would be of little use in a public
