ituHcized above. C. rifjiduhun^ Brothcrus, has the leaves more nearly oF the 

 ^'ime form, but has the seta spicalo<o, as indeed have all the known species 

 of this group. 



The seta is 2"5 cm. long; capsule inclined, Avide-monthed, smooth or very 

 lightly mamillose. Peristome large^ rod. 



ClI.ETOMITRTUM PKRLtEYE, DIxou, sp. TIOV. (PL 28. f5g. 6,) 



Sat robiistum; pulchre luteo-aureum^ sericeum ; caules longe repcnte^^, 

 densissime pinnato-ramosi, ramis erectis, brevibus, obtusis. Folia caulina e 

 basi snbauriculata oblonga^ breiiter oUiqiic acuminata^ acumine snbundulato, 

 acuto ; perconcava, profunde ^j^/i^r/y^/Zt^afa, pellucidaj Integra vel sxibintegra ; 

 cellular aiignstissimo lineares, infinuc laxiores, pellucidre, omnes lcevushna\ 

 Folia raniiilina siniilia, minora, brcvius acuminata. Folia perichrctialia 

 elongata, sensim longe filifonni-acnminata, undulata, remote runcinato- 



dentata. Seta circa 2 cm. alta, crassiuscula, Icevis. Theca inclinata^carvata,

Camp III, 2500 ft. (Xo. 30), Jan. 1913. 



Very distinct from any of the known species in the cliaractcrs above noted, 

 especially in having cells^ seta, and capsule (juite smooth, and the calyptra 



almost entirely so. 



IIYPOPTEHYGIACE.E. 



CYATHOPnoKUM SPiNOSUM, Flcisch, in sched. (Muse, frond. Archip. Ind. 

 No. 219) (Ilookerta spinom, C. Muelh, Syn< ii, 677). 



Camp VT^s4475ft. (Xo. 9). 



Very near C. Adiantum (GrifF.) i\[itt,j but larger in all its parts, and with 

 some slight differences in structure. Fleischer described it later as Ctjatlio- 

 plwrella spinosa^ and records it from British New Guinea. 



C. Lor'w\ C. MuelL, appears to me to be an undeveloped form of this. 



PiIIAC01*ILACE.E. 



llriACOPiLiJM sPECTABiLE, lioiuw. & Homsch. in Nov. Act. Acad, Ca3S. 

 Leop. xiv. (1829) 721. 



Several gatherings were made of this, from Camps VI h^ VI c, and 



Camps VIII-IX, all c. fr. One or two of the forms are very robust, and 

 come ncar^ apparently, to R.nova-gidnense^ Fleisch. (Hedwig, L (1911) 285). 

 I do not find it easj, however, from the description and figurcSj to grasp 

 the ditl'erences between it and 11. spectahile* 



THUIDIACE^. 

 TiiuiniUM sCABiainiACTKATUM, Dixon J sp. noY. (Ph 28. fig. 7.)
