if I had personally hunted for them oftener, to judge from the suc- 

 cess which has attended my few attempts in this way ; but I have 

 the whole vast range of zoology to engage my attention, to the ex- 

 tent of my abilities, and to that of my physical capabilities in this 

 climate, which does not permit of such exertions as, in Europe, 

 would be easily practicable. Indeed, 1 have had experience of the 

 penalties which too much enthusiasm, under a burning sun, is apt 

 to entail. Several species have been here indicated by name, which 

 have long been described by me, but are not yet published, though 

 they probably will be before this article is printed ; and to the 

 * Journal of the Asiatic Society of Bengal ' I therefore refer the 

 reader for the descriptions adverted to. The present list has also 

 been hastily drawn up, under pressure of other occupation ; but I 

 know full well how little chance I have of a season of coming leisure, 

 and have therefore obeyed at once the impulse to prepare such a 

 catalogue as I have now the pleasure of submitting to the notice of 

 the readers of the ' Annals and Magazine of Natural History.'

XXL — Descriptions of two species of British Jungermannise. 

 By Thomas Taylor, M.D._, Dunkerron, Kenmare*. 



JuNGERMANNiA FRAGiLiFOLiA, MSS. T. T. Caule procumbentc, sub- 

 pinnato ; ramis complanatis, alternis, remotiusculis, subcurvis : 

 foliis patentibus, subimbricatis, adscendentibus, ex angustiori basi 

 oblongo-rotundatis, recurvatis, integerrimis ; auriculis oblongo- 

 galeiformibus ; stipulis obovato-rotundatis, apice bifidis, integer- 

 rimis : foliis perichsetialibus obtuse pauci-dentatis ; calyce obovato- 

 cordato, tubifero ; perigonio subrotundo. 

 On mural rocks, accompanied by Jung, dilatata and Jung. Tama- 



risci, near Dunkerron, county of Kerry, 1829. 



This species scarcely exceeds half an inch in length, is of a 

 dusky reddish-brown colour, and collected into thin patches firmly 

 attached to the rock's surface, or more rarely to the barks of trees. 

 The branches are scarcely disposed in a pinnate manner, they are 

 sometimes fastigiate on one side. When wet the leaves ascend so 

 as not to touch one another, hence any pressure on their surface 

 is felt on the points of their connexion with the stem ; such con- 

 nexion is so frail that the top of the finger pressed against the 

 surface of the wet plant removes a multitude of leaves adhering, 

 so that, however paradoxical it may appear, a blind man may re- 

 cognise this species. The cells of the leaves are large in propor- 

 tion to the size of the plant ; and a few of the cells, sometimes 

 disposed in lines as in Jun^. Tamarisci, at other times irregularly 

 dispersed, are larger, more opake, and more intensely coloured
