PELLIE'^E. A tribe of Liverworts or 

 Hepaticae, nearly allied to the Jungerman- 

 nieae in the character of the fructification, 

 but having a lobed thalloid frond, traversed 

 by a mid nerve, from which the fruit-stalks 

 arise. 



British Genera. 



Blyttia. Fructification emerging from the 

 end of the rib below the apex of the frond, 

 at length dorsal. Perichsete 4-5-parted ; 

 lobes torn. Perigone herbaceous, tubular, 

 the mouth denticulated. Archegones eight 

 to twenty. Epigone persistent, torn at the 

 summit. Sporange 4-valved. Antheridia 

 dorsal, placed on the rib, covered by dentate 

 incumbent leaflets. 



Petalopliyllum. Fructification from the 

 upper surface of the plaited frond. Peri- 

 chaete broad, bell-shaped and toothed. 

 Perigone wanting. Epigone concealed in 

 the perichsete. Sporange bursting into 

 irregular laciniae. Elaters often branched. 



Fossombroma. Fructification emerging 

 from the end of the rib below the apex of 

 the frond, at length dorsal. Perichaete 

 obconic bell-shaped, the mouth crenate or 

 dentate. Perigone wanting. Archegones 

 few. Epigone persistent, torn at the sum- 



mit. Sporange circumscissile. Anlheridia 

 dorsal, situated on the rib, naked. 



Metzyeria. Fructification emerging from 

 the ventral side of the midrib of the frond, 

 Perichaete ventricose, at length bipartite. 

 Perigone none. Archegones few. Epigone 

 persistent, torn at the summit. Sporange 

 four-valved. Antheridia ventral, placed 

 on the rib, covered by incumbent dentate 

 leaflets. 



Aneura. Fructification emerging from 

 the ventral side, near the margin of the 

 frond. Perichaete short, lobed or torn. 

 Perigone wanting. Archegones few. Epi- 

 gone persistent, torn at the summit. Spo- 

 range four-valved. Antheridia immersed 

 in the back of special lobes of the frond. 



Pettia. Fructification emerging from the 

 dorsal side of the frond. Perichsete short, 

 somewhat cup-shaped, the mouth lacero- 

 dentate. Perigone wanting. Archegones 

 several. Epigone membranous, accompanied 

 by a few sterile archegones, at first, at the 

 lower part. Sporange four-valved. An- 

 theridia immersed in the surface of the 

 frond. 



Blasia. Fructification at first immersed 

 in the rib of the frond, then emerging from 

 the apex. Perichaete andperigone wanting. 

 Epigone membranous, with few sterile 

 archegones, at first, scattered toward the 

 lowest part. Sporange four-valved. An- 

 theridia immersed in the rib of the thallus, 

 more prominent below, and covered by 

 little dentate scales. 



Taryionia. Fructification sessile, inferior, 

 solitary and terminal to the frond. Perichaete 

 two-valved, splitting vertically. Perigoue 

 wanting. Epigone delicate, persistent, in- 

 vesting the sporange until maturity, some- 

 times evanescent above. Sporange bursting 

 by an irregular slit, or into fragments. An- 

 theridia immersed in the rib of the frond 

 below, covered by papillae. 



PELOMYX A, Greef .A genus of Amoe- 

 baea (Rhizopoda). 



This freshwater organism forms large 

 brown amoeboid masses, with lobose hyaline 

 pseudopodia. The ground-substance con- 

 tains nuclei, hyaline homogeneous highly 

 refractive, and 'delicate rod-like bodies. It 

 gives rise to swarms of minute Amoebae, 

 which become developed into flagellate free- 

 swimming organisms.
