The pericheetia are mostly concealed among the leaves. 

 Teeth of the peristome very long, whitish, crisped when 

 dry, the exterior linear-lanceolate, transversely barred, the 

 interior consists of slender elongated lacinise united at their 

 bases by a very shallow membrane. This species exceeds 

 10 inches in length, and is of a pale yellowish-olive colour.

1. H. Grevilleana ; caule laxe caespitoso, basi ramoso, surculis 

 adscendentibus, simplicibus, complanatisj foliis subim- 

 bricatis, patentibus, planiusculis, undulatis, oblongo-lan- 

 ceolatis, serrulatis, basi binerviis; seta elongata, sub- 

 flexuosa, scaberrima; capsula ovata, inclinata ; operculo 

 conico-rostrato ; calyptra sursum pilosa. — On trunks of 

 trees, in the Forest of Esmeraldos, at an altitude of 

 3,000 feet, 29 Nov. 1829, Prof. William Jameson, (Dr. 

 Greville's Herbarium.) 



Shoots shining, pale yellowish- green, scarcely 2 inches 

 high, more than £ of an inch wide. The undulated leaves 

 and pilose calyptra are anomalies in the genus. The outer 

 peristome is of sixteen strongly barred teeth, each with a lon- 

 gitudinal dark line, the inner consists of sixteen lacinise 

 united at their bases. Calyptra entire. This is one of the 

 most beautiful species of the genus, now dedicated to Dr. 

 Robert Kaye Greville in grateful testimony of the liberality 

 with which he has sent me his valuable cryptogaraic collec- 

 tions for examination.
