130 Hab. Lord Auckland's group and Campbell's Island ; on the ground, at the roots of trees in the woods. Var. /3, Campbell's Island.

Caules 1-2 unciales et ultra, densi, fragiles. Folia semiuncialia, nitida, fiavida, solidinervia, nervo in aristam longam excurrente ; perichatialia abbreviata, vaginantia, basi dilatata. Seta 1 une. longa, crassiuscula, vix torta. Theca suberecta, arcuata, substruinosa. Operculum tbeca longius, rostro tenui curvato. Calyptra fusca, apice rubra.

We are not acquainted with any species with which the present could be confounded. _D. longisetum, Hook., has the leaves of a similar form, but their nerve is very broad and indistinct, and the theca is erect. D. eapillaceum, Brid. (Bryol. Univ., vol. ii. p. 460), differs in the striated capsule. The stems of the var. /3 are four inches long.

Plate LYIII. Fig. V.— 1, a tuft, of the natural size ; 2, a stem of var. /3, of the natural size ; 3 and 4, leaves ; 5, theca and calyptra; 6, operculum: — magnified.

13. CAMPYLOPUS, Brid.

Peristomium simplex ; dentibus sedecim, bifidis v. bipartitis, imperforatis, cruribus sequalibus. Calyptra conica, fissa, rarius integra, basi fimbriato-lacera v. subciliata. TJieca sequalis, exannulata, exapophysata, nunc basi inaquali pseudo-apophysata.

1. Campylopus introficxus, Brid. ; caule erecto ramoso, foliis imbricatis e basi lata lanceolatis acuminatis piliferis nervo lato excurrente, seta madore curvata, theca elliptica striata, operculo conico. C. introflexus,

Hab. Lord Auckland's group and Campbell's Island; growing both in moist and thy places on the lulls.

This species is remarkable for the divergence of the filiform apices of its leaves and the broad nerve which is obscurely lamellated at the back, their margins also are so inflexed as to give them a subulate appearance. The numerous theca; arise from aggregated perichretia and are quite buried and concealed amongst the fobage. New Holland specimens of this moss exist in the Hookerian Herbarium under the name of D. pudicum, Hornsch. D. capitifiorum, Pal. de Beauv., from Bourbon, has more strict leaves, more distinctly lamellated at the back.

2. Campylopus flexuosus, Brid. ; caule erecto subramoso, foliis rigidiusculis concavis subulatis acuminatis nervo lato continuo, seta curvata, theca ovata striata, operculo recto cuspidato. C. flexuosus, Brid. Bryol. Univ. vol. ii. p. 469. Dicranum, Hedw. Sp. Muse. p. 146. t. 38. f. 1-6. Rook, et Tayl, Muse. Brit. p. 94. 1. 16.

Hab. Campbell's Island; barren.

14. LOPHIODON JIooLfl. et Will.

Peristomium simplex ; dentibus sedecim, pyrainidatis, per paria approximatis. Calyptra cucuLUformis.

This genus corresponds with the Cynodon of Bridel, a preoccupied name. The present species does not accord with Schwaegrichen's definition of Cynodontium, and we are thus obbged to establish a genus for its reception.

1. Lophiodox strictus, Hook. fil. et Wils. (Tab. LIX. Pig. II.) Var. j3, foliis longioribus flavidis, theca majore.
