and in August 1919 in Acliill Island, Co. Mayo. There can be little 

 doubt that this plant occurs in other of the many lakes which abound 

 along the west coast of Ireland. Its diminutive size, being the 

 smallest of the British Charo[)hytes, coupled with its usual habit of 

 growing in deep water, renders it liable to be easily overlooked. 



New localities have also to be recorded for Nitdla spanioclema, 

 Avhich was published as a new species in this Journal for Januarv 

 1919, and was collected by me in Lough Shannay-h, W. Donegal, in 

 August 1910. In the following year I found the plant still growing 

 in abundance in its original station ; in August 1919 1 could discover 

 no trace of it in Lough Shannagh, but in Lough Kindrum, some two 

 miles west, I found it growing s]>arsely in one small area. Last 

 autumn I received a parcel of Charophytes from Scotland from 

 'Mr. N. G-. J. Smith, collected by him in eolnpany with Dr. Annandale 

 in the deeper waters of various lakes. Among these gatherings was a 

 .sheet containing good specimens of N. spanioclema, colle'cted in 

 Loch Lubnaig, South Central Perthshire, in July 192 L The plant 

 was growing in some ten feet of water, about tlie same depth as the 

 Lough Shannagh plant. It may be a deep-water species requiring a 

 boat and a drag for its discovery, and for that reason not easily found. 

 Mr. James Groves and I are hoping to issue next j^ear a fasciculus 

 containing specimens of this plant and of other newly-found or newlv- 

 determined varieties of Charophytes as well as of certain rarer and 

 more critical species. 



NOTE ON A MOSS IN AMBER. 

 By H. N. Dixon, M.A., F.L.S. 



Through the kindness of Mr. W. N. Edwards, of the Dept. 

 of Geology, British Museum, I have had the opportunity of examining 

 an interestmg fragment of moss, embedded in a mouth-piece made 

 out of a piece of Burmese amber. I am indebted to Mr. Edwai-ds for 

 some of the following particulars : — 



The amber came from the Hukong Valley, in a district lying 

 quite in the north of Upper Burmah, and occurs in beds which are 

 considered to be of Lower Miocene age. It has long been known to 

 geologists (see Noetling, Bee, Geol. Surv. India, xxv. pt. 3, 1892, 

 p. 180; and xxvi. pt, 1, 1893, p. 31), but apparently the inclusa 

 remained unknown or unstudied untd in recent years some insects 

 were described in a series of papers by Prof. T.^ D. A. Cockerell. 

 These insects formed part of a collection, wdiich included the mouth- 

 piece with the moss-fragment, presented to the British Museum 

 (Natural History) by Mr. E. C. J. Swinhoe, of Mandalay, in 1921. 

 Apparentl}^ no plant-remains have previously been recorded fi-om 

 Burmese amber, and there do not appear to be any other recognizable 

 plants in the Swinhoe collection. 



The moss is a fragment of a branch, about 5 mm. in length, and 

 retaining a considerable number of leaves, some 7 or 8 of which are 

 perfect, the rest being more or less truncated. The cell-structure is 

 to a great extent obliterated, but sufficient indication remains to show
