we allow the difficulty of finding appropriate names, but these have nothing to 
recommend them. Three Hemipodii are noticed, H. pugnax, Dussumerii, and 
H. Taigoor, N. S., differing from //. pugnax in its more slender bill and white 
chin and throat. IJ. Descriptions of a few invertebrated animals obtained at the 
Isle of France. By ROBERT TEMPLETON, Esq. Four animals are described, illus- 
trated by a well-finished plate. III. On a remarkable species ofPteropine bat. 
By E. T. BENNET, Esq. On several of the bats there seems to be cavities and 
pouches connected with a glandular apparatus ; and in the one now described, 
there is a patch of long white hairs on each side of the neck, which Mr Bennet 
suspects is connected with some similar arrangement. This patch is about one 
inch in diameter ; the hairs are longer than those on the rest of the body, and 
they spring in tufts from a common centre, diverging to either side. In one or 
two other species, tufts somewhat similar have been observed, but in the pre- 
sent animal the greatest developement of it appears ; while in most of them we 
also have a modification of the form, and a difference in the number of the 
grinders, which may ultimately be made the basis of characters for a separate 
genus. This animal has been named Pteropus Whiteii, and two plates are de- 
voted to it, one to a figure of the bat itself, another to the appearance of the 
fur, taken from different parts of the body, greatly magnified. IV. Some ac- 
count of the Crustacea of the Coasts of South America, with descriptions of New 
Genera and species, founded principally on the Collections obtained by Mr Cum- 
ing and Mr Miller. By THOMAS BELL, Esq A valuable paper, continued 
from page 335 of Vol. I. but too long to be slightly noticed here. The first 
paper was devoted to the illustration of the genus Cancer brought home by the 
above named collectors, and three new species are figured and described, The pre- 
sent communication is devoted to the Oxyrhynchi. They are illustrated by five 
plates, containing representations of twenty-two species V. Some Observa- 
tions on the Economy of an Insect destructive to Turnips* By WILLIAM YARRELL, 
Esq Observations on the Athalia centifolice, which has, during the last year, 
committed so much damage to the turnip crops both in England and Scotland. We 
regret, however, that the range of this pest has not been more decidedly pointed out 
We do not know how far it has extended either to the south or north ; and it 
also appears to have passed, as it were, over some districts, and again appeared. 
On the Border counties of England and Scotland it was abundant, and committed 
severe depredations. Figures of the perfect insect, and its different stages, by 
Mr Westwood, accompany this paper. VI. Memoire sur une Nouvelle espece 
de poisson du Genre Histiophore, de la mer Rouge. Par M. E. RUPPELL, M. D. 
Membre Externe de la Societe Zoologique The description of Hist, immacu- 
latus, Rupp., which that gentleman considers distinct from the three previously 
known species of the genus. The colours of this fish are of a uniform dull 
blue above, changing to silvery on the lower parts ; the upper fins are blackish 
blue, the lower greyish and all spotless, with the exception of a dark mark on 
the pectoial at its lower part. The formula of the fins is 
P. 1 + 19 V. 3 + 0, D. 47 + 0, + 7. A. 10 + 0,0 + 7. C. 5 + 17 + 5. M. 13. 7. 
VII. On the genus OCTODON, and on its relations with CTENOMYS, Blain. 
and POEPHAGOMYS, F. Cuv. including a Description of a New Species of 
Ctenomys. By E. T. BENNET, Esq. F. L. S. &c. An excellent paper, entering 
in Mr Bennet's own manner, into the relations of the genera mentioned above, 
and illustrated by good figures of Octodon Cummingii, and Ctenomys Magella -
