COLLECTION OF BORNEAN MOSSES, 315 
CALLICOSTELLA PAPILLATA (Mont.), Jaeg. Decayed log in shade, Sekong, 
c.fr. (No. 86). 
Var. viripissiMA (C. Muell), Dixon, comb. nov. Damp shaded sandy 
bank, Tenom, с.Ёг. (No. 172). 
This plant appears to be identical with Callicostella viridissima, C. Muell. 
in sched. (€. pontianacensis, Par.), from Pontianak ; but as the difference 
from С. papillata is confined almost or entirely to the seta, which is papillose 
in the upper part, I think it should be considered a variety only of this 
species. Мг. Dinstead's plant, at any rate, shows no other distinguishing 
characters. 
С. PRABAKTIANA (C. Muell), Bry. jav. Sadong, Sarawak, 1900, leg. 
J. H. Cranston (No. 91). 
С. CHLORONEURA (С. Muell.), Fleisch. Rotting wood near stream, Sapong, 
near Tenom, с.Ёг. (No. 187). This plant has smooth cells, smooth nerves, 
leaves very little toothed above, and the seta papillose to the base. It appears, 
therefore, to agree with С. Mueller's New Guinea plant, which seems to 
differ from C. prabaktiana in precisely these characters—c/. M. Fleischer, 
M.... von Buitenzorg, iii. 1022.—1t would perhaps be better considered a 
subspecies of C. prabaktiana. 
RHACOPTLACEZÆ. 
RHACOPILUM SPECTABILE, Reinw. & Hornsch. Near Tenom (Nos. 169, 173, 
174, 180); Rundum, leg. E. О. Rutter, c.fr. (No. 228) ; Matang, Sarawak, 
1899, leg. St. V. Down (No. 23). 
LESKEACEZE. 
PELEKIUM VELATUM, Mitt. Jungle, Sekong, c.fr. (No. 113); decayed 
tree-roots in rubber plantation, Sekong, e.fr. (No. 114) ; rotting log by 
stream in shade, Sapong, near Tenom, c.fr. (with Æctropothecium, No. 206) ; 
Tabetang, near Sadong, Sarawak, 1901, leg. Rev. — Moore. 
THUIDIUM TRACHYPODUM (Mitt.). Shaded rocks by stream, Tenom, c.fr. 
(No. 193). 
T. pLUMULOsUM (Doz. & Molk.), Bry. jav. Rock in jungle-stream, Tenom 
(No. 188); rotting wood near stream in shade, Sapong, near Тепот 
(No. 189); rock by stream in shade, Sapong, near Tenom (Nos. 190, 192). 
T. GLAUCINOIDES, Broth. Rock near waterfall, Sapong, near Tenom, 
d plant (No. 191). This has a very distinct appearance, having the
