1. Grimmia pidmnata, Hook, et Tayl. ; dense pulvinata, foliis lanceolato-oblongis superne carina tis 

 repente piliferis evanidinerviis margine recurvo, capsula in pedicello arcuato demissa ovali striata, calyptra 

 mitrseformi, annulo magno, operculo rostrato. — Muscol. Brit. Dryptodon, Brid. Dicranum, Schwagr.

Yar. /3. African a ; liumilior, capsula breviore, operculo conico mamillato brevissimo, dentibus breviori- 

 bus. — Eissidens pulvinatus, var. /3. Africanus, Hedw. Sp. Muse. t. 40. G. cygnicolla, Taylor. 

 Hab. Northern Island, Colenso. Auckland, Knight. (A native of England.) 



A native of South Africa, Australia, and Europe ; liable, on account of the short operculum, to be confounded 

 with G. orbicularis, Bryol. Europ., which is a more delicate Moss, with a dimidiate calyptra and a cribrose peristome.

 phano snblsevi attenuatis siccitate crispulis, capsula in pedicello cygneo subpendula ovali striata siccitate 

 angulosa, operculo conico-rostrato, annulo lato, peristomii dentibus bifidis. — Greville, Scot. Crypt. Flora, 

 if. 100. Hook, et Tayl. 



Hab. Middle Island : Ship Cove and Port Cooper, Lyall. (A native of England.)
