PELLIE'^.— A tribe of Liverworts or 

 Hepaticfe, nearly allied to the Juugerman- 

 niese in the character of the fructification, 

 hut having a lobed thalloid frond, traversed 

 bv a mid nerve, from which the fruit-stalks 



arise. 



British Genera. 



Blyttia. Fructification emerging fi'om the 

 end of tlie rib below the apex of the frond, 

 at length dorsal. Perichsete 4-5-pnrted ; 

 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. 



PetalophyJlum. Fructification from the 

 upper sui-face of the plaited frond. Peri- 

 chtete broad, bell-shaped and toothed. 

 Perigone wantLug. Epigone concealed in 

 the perichsete. Sporange bursting into 

 iiTegiilar lacinise. Elaters often branched. 



Fossombronia. Fructification emerging 

 from the end of the rib below the apex of 

 the frond, at length dorsal. Perichsete 

 obconic bell-shaped, the mouth crenate or 

 dentate. Perigone wanting. Archegones 

 few. Epigone persistent, torn at the sum- 



mit. Sporange circumscissile. Antheridia 

 dorsal, situated on the rib, naked. 



Metzyeria. Fructilication emerging from 

 the ventral side of the midrib of the frond, 

 Pcrichsete ventricose, at length bipartite. 

 Perigone none. Archegones few. Epigone 

 persistent, torn at the summit. Sporange 



four-valved 

 on the rib, 

 leaflets. 



Aneura. 

 the ventral 

 frond. Perichaete 

 Perio-one wanting 



Antheridia ventral, placed 

 covered by incumbent dentate 



Fructification 

 side, near the 



emerging 



from 



of the 



short, lobed or torn. 



Archegones few. Epi- 



gone persistent, torn at the summit. Spo- 

 range four-valved. iintheridia immersed 

 in the back of special lobes of the frond. 



Pellia. 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 fom-valved. An- 

 theridia immersed in the surface of the 

 frond. 



Blasia. Fructification at first immersed 

 in the rib of the frond, then emerging fi'om 

 the apex. Peiichgete and perigone 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. Perichsete 

 two-valved, splitting vertically. Perigone 

 wanting. Epigone delicate, persistent, in- 

 vesting the sporange until maturity, some- 

 times evanescent above. Sporange biu'sting 

 by an irregular slit, or into fragments. An- 

 theridia immersed in the rib of the frond 

 below, covered by papiUfe. 



PELOMYX'A, Greef .— A genus of Amoe- 

 bpea (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 lise to swarms of minute Amoebae, 

 which become developed into flagellate free- 

 swimming organisms.
