flora, as in the former, by reckoning up how many are absent, how 
many present, out of each hundred or section. 
Chapter VIII. is devoted to a detailed account of the altitudes 
reached by the several species : first upon the Grampians ; secondly, 
upon the mountains of the North of England (Lakes and York- 
shire). A few of the upper limits attained in other less explored 
districts are added, as a kind of supplement to or check upon the two 
former lists. The upper and lower limits of the plants are both 
given, and the names succeed each other in a descending series. The 
desirableness of a careful survey of the heights attained in Wales is 
very justly insisted upon; and we must urge that duty as no unwor- 
thy undertaking for a strong-limbed and energetic botanist who 
would do his science some service, and turn his knowledge of species 
to account. 
In Chapter IX. the Orders are contrasted,—first, according to 
their prevalence among British plants in Europe, and in the world ; 
secondly, as they occur in the west and east, in the south, middle, 
and north of Britain; and thirdly, according to their proportion in 
the three stages or zones of elevation. 
In Chapter X. the author gives us the general results or recapitu- 
lation of his labours. It is in accordance with Mr. Watson’s dislike 
of general remarks, that he is himself especially diffident and cautious 
in suggesting conclusions. If it may be said, with some truth, that 
the fourth volume of the ‘ Cybele’ does not offer many new solutions of 
the grand problems of geographical botany, it should be remembered 
‘that such was not the professed object of its author. But, as regards 
the distinctive features of the flora of Britain, there is in the con- 
cluding chapter a mass. of most interesting information, of which, 
however, space will not here permit a sufficiently extended notice. 
We must reserve the analysis and discussion of this part of the subject 
for a future occasion.

Description or A New Species or Cuscus (C. ornatus) 
FROM THE Istanp oF Batcuian. By Dr. Joun Epwarp 
Gray, F.R.S., V.P.Z.S., Pres. Ent. Soc., etc. 
Mr. Wallace has sent to the British Museum a series of Mammalia 
collected in the Island of Batchian in the year 1859. 
The most interesting specimen is a new species of the genus Cuscus, 
belonging to the section of the genus which has the inner surface of 
the ears bald. It may be thus described :— 
Cuscus ORNATUS. 
Male pale golden-brown ; back rather darker, with small irregular 
white spots; crown and back with a narrow: longitudinal blackish
