20. Hypnum Terra-Nove, Brid. ; caule pinnatim Tamoso, ramis incurvis simplicibus, foliis secundis 
circinnatim falcatis ovato-lanceolatis subintegris enerviis, perichetialibus elongatis recurvis subcrinitis sub. 
serrulatis, theca suberecta cylindracea, operculo brevi conico apiculato. H. Terre-Nove, Brid. Bryol. Univ.

Var. B, australe; foliis e basi lata gradatim attenuatis subpiliferis integerrimis. 
Haz. Var. 8. Campbell's Island; on decayed vegetable matter in the woods. 
Our specimens do not sufficiently depart from the description of Bridel to warrant our considering them as a 
distinct species ; the only difference appears to lie in the entire perichzetial leaves and the cauline being probably more 
gradually attenuated from the base upwards. The seta is half an inch long. Operculum convex, subconical, 
or nearly hemispherical. +: volo, fe ed der

25. HOOKERIA, Sw. 
Peristomium duplex; exterius dentes sedecim, basi liberis; inferius membrana erecta, in lacinias sedecim cari- 
natas fissa, eiliolis interjectis plerumque nullis. Calyptra mitreeformis.

1. HookerIa nervosa, Hook. fil. et Wils.; caule parce fastigiatim ramoso, foliis imbricatis erecto- 
patentibus ovato-lanceolatis acuminatis carinatis marginatis integerrimis solidinerviis, theca erecta ovato- 
cylindracea apophysata, calyptra basi fimbriata. (Tas. LXI. Fig. V.) 
Has. Lord Auckland’s group; on twigs of bushes in ravines, at an altitude of 500 feet, rare. 
Caules fere 1} unciales, dense conferti, ramis fastigiatis. Folia arcte imbricata, acuminata v. longe cuspidata, 
margine incrassata, nervo valido subexcurrente, pallide viridia, siccitate appressa, areolis rotundatis ; perichetialia 
breviora, erecta, elliptica, obtusiuscula. Seta 3-4 lin. longa, rubra, apice. scabriuscula. Theca parvula, suberecta. 
Calyptra conico-subulata, basi fimbriata, apice scabriuscula, fusco-brunnea. 
This moss closely resembles the Daltonia splachnoides, Schwaeg., and cannot be generically removed from that 
plant. It differs specifically in the inflorescence not being hermaphrodite, in the shorter peristome, in the sporules 
being twice the diameter, the calyptra twice as long, less conical, the seta shorter and thicker, the theca more ob- 
long; the leaves wider, more patent, carinate, and nerved to the very apex or beyond it. We have South American 
specimens of D. splachnoides ; but none corresponding with the moss now before us.

2. HookerIA pulchella, Hook. fil. et Wils.; caule procumbente distiche ramoso, ramis compressis, 
foliis confertis imbricatis subdistichis obovatis obtusis marginatis seminerviis, theca suberecta oblonga apo- 
physata, operculo rostrato, calyptra basi dense fimbriata superne glabra. (Tas. LXIT. Fig. 1.) 
Has. Lord Auckland’s group; on bushes and the ultimate branches of trees, about 500 feet above the 
sea, rare, but abundantly fruiting.

albida, integerrima, nervo tenui ad medium evanido instructa, areolis parvis rotundatis inferioribus majoribus; peri- 
chetialia minora, erecta, ovata, obtusa, subconvoluta. Seta vix semiuncialis, apice scabriuscula, luride rubra, infra
