of a total number recorded for Spitzbergen, as far as I am aware, of just under 
200. The mosses of Spitzbergen have been so carefully studied and enumerated 
by Berggren in the Musci et Hepaticae Spetsbergenenses (K. Vet.-Akad. 
Handl. XIII. 1875) that not much roomhas been left for further additions. Inthis 
work he enumerates 189 species of mosses. The only literature that I know 
which has added further to the list of mosses is a paper of Hagen 's on the Mosses 
and Hepatics of Prince Charles Foreland, Spitzbergen, (Trans. Bot. Soc. Edin, 
XXIII. 1908), in which 3 species are added, and one by Bryhn, "Bryophyta 
pro flora Spitzbergensi nova," (Nyt Mag. for Naturvidensk, Bd. XLVII. 1909), 
adding 4 more. These bring the number up to 196. It is possible that I have 
overlooked some papers on the subject, but I believe that the above pretty well 
exhaust the list. 
The 82 species in the present collections comprise 5 distinct species new to 
the group, in addition to one or two which are in the nature of segregates, and 
may be included by Berggren in the "aggregate" species recorded by him. The 
5 additional species are as follows: — 
Sphagnum subsecundum var. contortuni 
Grimmia commutata 
Orthotrichum rupestre 
Cinclidium stygium 
Amhlystegium serpens 
In addition to these, Sphagnum subnitens and Philonotis tomentella have 
not been distinguished from S. acutifohum and P. fontana respectively. I give 
further particulars as to these and a few other plants of interest. 
Sphagnum subsecundum var. contortum Schimp. — Advent Bay; 25 June, 
V. S. Summerhayes (28a). 
Sphagnum subnitens Russ. & Warnst. — Advent Bay; 18 July, V. S. Summer- 
hayes (123b). Probably included by Berggren in the aggregate Sphagnum 
acutifolium. 
Sphagnum fimbriatum var. concinnum Warnst. (Syn. S. teres var. concinnum 
Bergg. ; S. fimbriatum var. arcticum Jens.);det. J. A. Wheldon. An interesting 
and difificult form which has been placed under two or three different names; it 
has rather the habit of S. Girgsnsohnii, but the stem leaves are rather those of 
S. fimbriatum. It was collected by V. S. Summerhayes, Cape Boheman; 12-16 
July, (95b). 
Dicranum Starkii Web. & Mohr. — Bear Id.; 17-20 June, V. S. Summerhayes 
(9ad). A very puzzling, sterile plant, which appears to belong here, with the 
habit of Bhndia acuta, and a very fine leaf subula, which is denticulate for some 
distance down. The alar cells are too strongly marked for D. fulvellum. 
Dicranum Bonjeani De Not. — Bear Id.; 13-20 July, V. S. Summerhayes 
(9p). Advent Bay; June 25, (28d). The type form: Berggren found only 
var. jumperifolium. 
Grimmia commutata Huebn. — Klass Billen Bay; 14 Aug., C. S. Elton (L25). 
A very remarkable form; robust, brown, with the leaves decidedly crisped when 
dry, the upper cells larger and clearer than in the usual, form, and the cells and
