MISCELLANEOUS NOTES. 587 



contorted when dry ; and the peristome also presents not unimportant dif- 

 ferences. From most of the allied autoicous species of Drachymeninm it is at 

 once distinguishable either by the turgid sub- pendulous capsule, not narrow 

 and sub-erect, or by the leaves not being twisted when dry, or by the ex- 

 tremely narrow entire border. B . lanceolatum , 'Rook. fil. and Wils, from 

 Tasmania resembles it very closely in leaf characters, but the capsule is quite 

 distinct. On the other hand, B. glaucum (C. M.) from Ceylon, to which it is 

 probably most nearly related, has a turgid capsule, but according to the 

 ilescription (I have not been able to see a specimen) differs at once in having 

 the leaves gathered into gemmiform rosulate tufts, very bright and shining, the 

 perichfetial leaves differing little from the cauhne ones, the neck of the capsule 

 longer (compared byC. Miiller with that of Leptohryi(mj)yriforme'). and the 

 structure of the peristome different. 



The internal lamelliB of the peristome teeth in B.turgidum are very strikingly 

 developed. I do not remember seeing them so high in any species of Bryum 

 or indeed in any other moss.

 me with a specimen of the moss which I propose to exhibit at the next meeting of the

Xo. XXIV.— AN ACTIVE MUD VOLCANO. 



Yesterday, when out shooting close to my camp, I discovered an active mud 

 volcano. It is on a small hill about 150 ft. high and about two miles from the 

 Irrawaddy river ; the volcano has three mouths, two about ten feet apart and 

 the third about 150 ft. further to the west, all three are bubbling and throwing 

 out a clayey oily mod which I suppose means that there is oil at the bottom 

 of them. 1 could hear rumblings in the earth at a good depth. I shoved a 

 bamboo down for some ten feet in one of the mouths. 



Mud volcanoes of this desci'iption are common in the Minber aud Myingyan 

 Districts of Upper Burma, and it is there that the famous petroleum oil wells 

 of Burma are, and if oil is found there, why should it not be found here also ?
