which Mr. Thiselton-Dyer uses the word, where he says : ‘ The type- 
collection is certainly not there (i. e. Linnean Society, Burlington House), 
for the simple reason that it is where it has always been since Mrs. 
Griffiths' death, at Kew.' It is evident that in neither of these cases 
could the word ‘ type ’ be used in the most limited sense, i. e. as 
referring to the actual specimens on which the original descriptions of 
the plants were founded, since it is generally understood that Mrs. 
Griffiths did not describe any new species. Our object in giving the 
list was to indicate, for the use of actual students of algology, where 
the special herbaria of previous algologists are to be found, since these 
would obviously represent the species as understood by them. Mr. 
Thiselton-Dyer states that Mrs. Griffiths' type-collection is at Kew, and 
that ‘ this fact is well known to critical algologists, for Dr. Bornet 
writing to me mentions incidentally: L'herbier de Mrs. Griffiths et 
celui de Berkeley sont conserves au Musee de Kew.' The evidence 
on which our statement is founded is as follows: — 
1 st. In the Proceedings of the Linnean Society, bearing date 
November 10, 1858 (vol. iv. pt. i), the following words occur : ‘ The 
valuable collection of British Algae formed by the late Mrs. Griffiths, 
arranged according to Harvey’s Manual of British Algae. Presented 
by the subscribers to a fund for its purchase.' 
A similar statement is repeated on p. lxxxviii. 
That this collection was purchased as the special one of Mrs. 
Griffiths seems evident from the fact that Dr. Cocks’ collection of 
marine algae in the possession of the Linnean Society is described as : 
A collection of British Marine Algae, formed by Dr. Cocks of 
Plymouth. That the collection was purchased by the Society as the 
special collection made by Mrs. Griffiths for her own use, is confirmed 
by a letter received by one of us (B), from Mr. W. Carruthers, F.R.S. 
2nd. The collection in the Kew Herbarium was received at Kew 
four years later , according to the Kew Report, 1862, and was presented 
by Lady Burdett-Coutts. It presumably consisted of Mrs. Griffiths’ 
very large stock of duplicates. 
3rd. It is certain that both Mrs. Griffiths and her daughter gave 
away other collections made by the former, for there is one collection 
at the Devon and Exeter Institution at Exeter, presented by Miss 
Griffiths in 1861, and another exists in the Museum at Torquay. 
Hence the word ‘etc.’ placed after the words ‘Linnean Society' in 
our list (p. 66).
