142 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.

Plate LXI. Fig. IV. — 1, a specimen of the natural size; 2, 3, and 4, leaves; 5 and 6, theca? : — magnified.

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.

Plate LXI. Fig. V. — 1 and 2, specimens of the natural size ; 3, a leaf; 4 and 5, perichretial leaves ; 6, theca ; 7, operculum; 8, teeth; 9, calyptra; 10, base of ditto : — magnified.

2. Hookekia pulcliella, Hook. hi. et Vils. ; caule procumbente distiche ramoso, ramis compressis, foliis confertis imbricatis subdistichis obovatis obtusis marginatis seminerviis, theca suberecta oblonga apophysata, operculo rostrato, calyptra basi dense fimbriata superne glabra. (Tab. LXn. Kg. I.)

Hab. Lord Auckland's group; on bushes and the ultimate branches of trees, about 500 feet above the sea, rare, but abundantly fruiting. Caules semiunciales et ultra, subphmatim ramosi ; ramis subcomplanatis molhbus. Folia late obovata obtusa interdum apiculata, flaccida, pellucida, lateraba patentia, antica posticaque subappressa, margine tenue cartilaginea, albida, integerrima, nervo teniu ad mediiun evanido instructa, areohs parvis rotundatis hiferioribus majoribus ; perichcetialia minora, erecta, ovata, obtusa, subconvoluta. Seta vix semiunciahs, apice scabriuscula, luride rubra, infra
