180 МЕ. W. MITTEN ON THE SPECIES OF 
ramosis bipinnati, cum foliis ubi latiores 2 mm. lati. Folia pallide viridia stramineaque 
nitentia. Peduneulus sesquiuncialis. Theca 3 mm. longa, cinnamomea. 
This, in its bipinnate ramification, agrees only with the Indian Æ. rubicundus, Mitt. 
(Stereodon rubicundus, Mitt. in Journ. Linn. Soc., Bot. iii. Suppl. 108), and differs from it 
in being more slender. Both this and Æ. attenuatus have a great similarity to Е. Sul- 
livantii, so that, as in the ease of the species found in America, unless closely examined 
it is very easy to confound species which are really quite distinct.

majora subconformia. Тһеса in pedunculo brevi ovalis erecta, operculo conico obtuso, 
peristomio dentibus pallidis, processibus in membrana brevi latiusculis fuscis obseu- 
riusculis, ciliis nullis.
