The beautiful figure in tbe BryoL Javan. of G. Mohcccensis, 

 V. d. Boscb. et Lac. t. 196, gives a good idea of the size and ge- 

 neral appearance of the Samoan species — which, however, has 

 narrower leaves, with the lower margins reflexed. 



G. ANGUSTiFOLiAj sp. n. Folia compressa, lateralia, patula, elongate 

 lanceolata, sensira acuta, quater plicata, dorso fevia, ncrvis obsoletis, 

 marginibus plus minus recurvis revolutisve superne serruktis, cellulis 

 elongatis angustis, ad angulos paueis brevioribus latioribusque ; pen- 

 cliaitiaha quam eaulina dimidio breviora, erecta, ovato-Iauceolata, apice 

 acurainato dentato ; theca in pedunculo thecam cylindraeeam iucli- 

 natara sequante; operculum cuvvirostrum.

This agrees with G, Samoana and G, Moluccensis in having its 

 capsule exserted , but the leaves are little more than half as Avide 

 as in either of those species, and their nerves, as in G. Samoana^ 

 obsolete. 



G. setigera, Sail Amer. Expl. Exped. t. 18, B (JEndotricMm) , 

 from the Figi Islands, has the teeth of its external peristome 

 trabeculate within, and the internal peristome with narrow pro- 

 cesses equalling the external teeth in length, and supported on a 

 membrane which extends to near their middle, in these parti- 

 .culars agreeing with G, cuspidata {Esenheckid), Mitten in Hook. 

 Joum. of Bot. vol. viii. p. 263, from Moreton Bay, Australia, and 

 thus differing from G. plicata and its allies in the more con^yAete 

 evolution of the peristome, upon which is founded, by M. Sclum- 

 per, the genus Huptycldum {Euptycldum^ Muscorum Neocaledom- 

 corum genus novum, Dresden, 18G5),_E. neocaledonicum^ Schimp., 

 the only species there mentioned, being, so far as can be seen 

 from the excellent plate, t. 1, identical with G, cuspidata. 



All the very handsome Mosses referable to Garovaglia app<?ar 

 to be destitute of a creeping stem, and in this respect, as well as 

 in the leaves and general appearance, seem to approach very nearly 

 to Cladomnion and Ptijclwmnion of AVilson.
