collection of dried specimens, however, was secured for the Herbarium of 
tho Colonial Museum, at Wellington, which will prove valuable for future 
reference. No. 2, pl. xxxviii., shows a characteristic outlier of the trachy- 
dolerite rock frequented by immense flocks of sea-fowl. No. 8, pl. xxxviii., 
is the best harbour in the Island, and a favourite anchorage for sealers.

Tuarnnus cespitosus e podetiis formatus.  Podetia intus solida dense granu- 
losa, strato corticali tenuissimo e gonidiis veris constante.: Apothecia 
plura congesta capituliformia intus alba solida lecanorina,* juvenilia crasse 
marginata; excipulo thallode albo, corticis structura radiatim disposita, 
gonidiis veris nullis. Sport in ascis cylindrico-elongatis octone uniseriales 
oblongo-ellipsoidez simplices subluteole, longit. 0009 mm., crassit 0°0025 
mm. Cephalodia plura in apicibus ramorum brevium congesta, glauco- 
ecrulescentia, intus > granulis gonimis flavo-viridis, in nodulis 2 ad 4 dispositis, 
omnino constantia. 
- Supra saza. 
Obs.—The discovery of the spores, now shown to be simple, distinctly 
shows that Colenso’s lichen belongs to the genus Pilophoron. Th. Mr 
Fries, in his ** Monogr. Stereocaulorum et Pilophororum," p. 66, under 
** Species minus cognita," remarks that Stereocaulon colensoi is perhaps a form 
of Ster. argus. This view must now be abandoned, as the latter plant has 
cylindrico-fusiform multiseptate spores (see fig. 1*, pl. xxxix). Babington, 
on the other hand, eonsiders it allied to Ster. ramulosum, but the same ob- 
jection exists to any proposal which would place Colenso's plant under the 
genus Stereocaulon. 
2. Myriangium duriei (Mnt. et Berk.). 
Thallus nullus. Apothecium tuberculiformis e matrice erumpens (diam. 
circiter 8 mm. vel amplius) toro crasso parenchymatico carbonizato margina- 
tum ; epithecium carbonizatum ; hymenium parenchymaticum luteo-fuscum 
* Quia margo est thallinus, lecanorina nominatur.
