20. Hypxi'ii Terra-Nova, Brid. ; caule pmuatim ramoso, ramis incurvis siniplicibus, foliis secundis circiimatim falcatis ovato-lauceolatis subintegris enerviis, perichEetialibus elongatis recurvis subcrinitis subserrulatis, tbeca suberecta cylindracea, operculo brevi conico apiculato. H. Terrfe-N 1 ova?, Brid. Brgol. Univ. vol. ii. p. 619. (Tab. LXI. Kg. IV.)
Var. 0, anstrale ; foliis e basi lata gradatim attenuatis subpiliferis integerrimis.
Hab. Var. /3. Campbell's Island ; on decayed vegetable matter in the woods.
Our specimens do not sufficiently depart from the description of Bridel to wan-ant our considering them as a distinct species ; the only difference appears to lie in the entire perichsetial leaves and the cauline being probably more gradually attenuated from the base upwards. The seta is half an inch long. Operculum convex, subcorneal, or nearly hemispherical.

25. HOOKEKIA, Sw.
Peristomium duplex ; exterius dentes sedecim, basi liberis ; interim membrana erecta, in lacinias sedecim carinatas fissa, ciliolis interjectis plermnque nullis. Calyptra mitrfeformis. 1. Foliis marginatis midique imbricatis.
1. Hookema nervosa, Hook. fil. et TVils. ; caule parce fastigiatim ramoso, foliis imbricatis erecto-patentibus ovato-lanceolaiis aenminatis carinatis marginatis integerrimis soliclinerviis, tbeca erecta ovato-cylindracea apophysata, calyptra basi fimbriata. (Tab. LXI. Kg. V.)
Hab. Lord Auckland's group; on twigs of bushes in ravines, at an altitude of 500 feet, rare.
Catdes fere l unciales, dense conferti, ranhs fastigiatis. Folia arete imbricata, acuminata v. longe cuspidata, inargirje incrassata, nervo vahdo subexcurrente, pallide viiicba, siccitate appressa, areolis rotundatis ; perichatialia breviora, erecta, elliptica, obtusiuscida. 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 Baltonia splacJinoides, Schwaeg., and cannot be generically removed from that plant. It differs specifically in the inflorescence not being hermaphrodite, in the shorter peristome, in the spondes being twice the diameter, the calyptra twice as long, less conical, the seta shorter and thicker, the theca more oblong; the leaves wider, more patent, carinate, and nerved to the very apex or beyond it. We have South American specimens of B. splacJinoides ; but none corresponding with the moss now before us.
