OUTLINES OF PERIODICAL LITERATURE. 351 
most perfectly organized flowering plants: and by Mr. Brand on the proper 
mode of arranging the Society’s Herbarium and forming a catalogue for re- 
ference; his scheme is most ingenious, and comprises objects and principles 
which met with general approbation. At the “ Zoological,” a new species of 
Perameles was exhibited by Mr. Gray, who proposed to name it the P. 
gunnii, in honour of its discoverer. Ina letter from Captain Harris at the 
Cape, he relates his discovery of a new species of antelope: it is denominated 
Aigocerus niger, the sable antelope, and its measurements and characters are 
described. Mr. Ogilby characterized the Macroscelides alexandri, M. mela- 
notis, Chrysochloris damarensis, Bathyergus damarensis, and Graphiurus ele- 
gans, as new mammalians, and then distinguished certain peculiarities in the 
structure of the hand, in a living Galaga: it is a new species, and he wished 
it to be called the Otolicyus garnetii, in honour of the gentleman who enabled 
him to make the description. Mr. Owen’s outline of the comparative anatomy 
and zoological relations of the Nubian Giraffe, founded on dissections of one 
female and two males, is an elaborate, perspicuous, and exceedingly instruc- 
tive document. Mr. Martin exhibited an “insectivorous animal” to the 
society: he established a new genus for its reception, and characterized it 
under the generic appellation of Echinops, with the specific title of E. telfairi 
in memory of a lamented and zealous corresponding member. Mr. M.’s 
characterology seems comprehensive and accurate. Sokinah is this creature’s 
Malabarian name. A new species of swan was shown by Mr. Yarrell, who 
denominated it Cygnus immutabilis, with reference to the unchangeable co- 
lour of its plumage. A list is given of the communications laid before the 
section of zoology and botany at the last meeting of the British Association, 
and some of these, or authentic extracts, are promised to appear in future 
numbers of the Annals. The miscellanies relate to two magnificent works 
on the Orchidaceous plants ; to collections of Scottish and American mosses; 
to the Panopzea australis, its internal and external organization ; to the Ody- 
neri, their metamorphoses and industry; to the Lestris parasiticus, shot in 
the county of Durham ; to the occurrence of copper in plants; and to the 
Falco islandicus, shot in Yorkshire: this instance and another previously 
known are held sufficient tor assigning to this bird a place in British Orni- 
thology. ‘ October” terminates with the usual tables of meteorological ob- 
servations. 
IX.—Setting out with a note from Prof. Ehrenberg on the organic origin 
of the potstones or Paramoudras of Whittingham, this number has for a se- 
cond article, an admirable memoir by Capt. Cook on the genera Pinus and 
Abies, with remarks on the cultivation of some species: the captain’s obser- 
vations are most important, with reference alike to science and to silvan eco- 
nomy, and his suggestions offer high claims to the attention of forest-owners, 
wood-merchants, and governments. Two letters from Capt. DuCane convey 
much curious information relating to the metamorphoses of Paleemon varia- 
bilis, the ditch prawn, and Crangon vulgaris, the common shrimp, and his ae- 
count of the remarkable changes which these creatures undergo in passing 
through their successive states, is illustrated by twelve finely lithographic 
figures. In notes on Vespertilio /eisleri, the hairy-armed bat, Mr. Paine dis- 
tinguishes the animal by zoological characters, and he concludes that its oc- 
currencein the eastern part of Norfolk is not so rare as has been represented, 
Resuming his descriptions of the new British insects indicated in Mr. Cur-
