86 THE VOYAGE OF H.M.S. CHALLENGER. 



Caulis 1 cm. longus, pallidus, crassiusculus ; folia 1 mm. longa, e cellulis rotundatis 

 minutissime granulatis limitibus angustis areolata, pallida, carnosula, hie illic roseo tinctis. 

 Tubus periauthii 1 cm. longus vel brevior, pallidus, radicellis pallidis sparsis.

A small plant which might at first sight be taken for fragments of Jungermannia 

 colorata from the colour of its foliage. The tube is probably at first apical, but is left 

 behind by continuation of the stem, on which several of different lengths are produced. 

 In tbe very small quantity available for examination no aperture is observable over the 

 top of tbe tube, the stem being to all appearance continuous, but the tubes are fistulose, 

 and thus not to be confounded with flafrella or stolons. 



Balantiopsis purpurata, Mitt., n. sp. 



Caulis procumbens, subsimplex ; folia explanata, lobo ventrali patente divergente ovato, 

 apice dentibus spiniformibus parvis 2-4 armato, basi dorsali cum lobo dorsali quadruple 

 minore late ovato apice 3-4 spinoso dentato appresso breviter confluente ; amphigastria 

 parva, profunde quadripartita, laciniis subulatis. 



Csespites depressi, lati, caulibus laxe intertexti 1-2 cm. longi plerumque simplices, 

 foliis pallide fusco albidis 2 mm. latis colore roseo purpureove tinctis, e cellulis elongatis 

 limpidis areolatis.

This appears to grow in the same manner as Kantia trochomauis when the tufts are 

 sufficiently dense that the stems overrun each other. It is not so white as Balantiopsis 

 diplophylla, with which it agrees in having the two lobes of its leaves connected with a 

 keel, which is, however, much shorter than in that species ; besides which the outline of 

 the leaf is ovate, the terminal teeth small, and the amphigastrium deeply cleft into four 

 narrow lacunae, arranged in the divergent manner usual in Lophocolea and Chiloscyphus. 1 



1 There are two other species which come near to this : — 



Balantiopsis versicolor, Mitt., n. sp. — Caulis procumbens ramis remotis divisus ; folia lobo ventrali ambitu 

 ovato medio convexo margine, ventrali recurvo, lobo dorsali appresso caulem tegente dimidio minore, ambobus 

 apicibus emarginatis bidentatis marginibus ubique dentibus ciliiformibus fimbriatis basi in carina brevissima 

 coalitis ; amphigastria profunde biloba, lobis divergentibus oblongis obtusis ubique ciliatis. 



Caulis 2-3 cm. longus ramis remotis alternis cum foliis 2 mm. latus. Folia pallide fusca, apicalia plerumque 

 purpurata. 



Valdivia, Sainthill, Reed; also a specimen in the British Museum Herbarium, marked "Oregon, Lobb," 

 probably also Chilian. 



Rather smaller than /lalimtiojisis purpurata, and not quite so soft and flaccid, with both lobes of the leaf 

 ciliated all round the margins as well as round the margins of the differently shaped amphigastrium ; in the
