Paul Marchal, "Observations sur l'Ammophila affinis," Arch. de Zool. exp. et génér., ii. Série, t. x., 1892. Similar cases in which the specific instinct is less powerful and individual initiative greater. Here is, for instance, the case of the Chlorion, where each animal possesses more considerable initiative. It attacks the Cockroach.
But experiments of this kind are from the nature of the case difficult if not impossible. There is, however, another method namely, to take a character which is certainly to some extent hereditary, and then to ascertain by experiment if it is 'acquired. If it be proved that a hereditary character was originally somatogenic, it follows that somatogenic characters in time become hereditary. Zool.
Taking advantage of the space of the plate, figures of the following species from the same country, which have not hitherto been illustrated have been added. They were described or noticed in the list before referred to. Cystignathus dorsalis, t. 1. f. 2. Phryniscus Australis, t. 2. f. 1. DUM. AND BIB. E. GEN. viii. 725. Bombinator Australis, GRAY, PROC. ZOOL. SOC. 1838. 57. III. Mr.
The case is very different with the African ostrich, for the male is somewhat larger than the female and has finer plumes with more strongly contrasted colours; nevertheless he undertakes the whole duty of incubation. Mr. Sclater, on the incubation of the Struthiones, 'Proc. Zool. Soc. June 9, 1863.
[Footnote 1: Proceed. Zool. Soc. London, 1849. p. 144, note. The original description of TEMMINCK is as follows: "Elephas Sumatranus, Nob. ressemble, par la forme générale du crâne
Head of female Aethopian wart-hog, from 'Proc. Zool. Soc. 1869, shewing the same characters as the male, though on a reduced scale. The tusks in the lower jaw are sharper than those in the upper, but from their shortness it seems hardly possible that they can be used as weapons of attack.
Specimens of the true Singhalese species were, however, received in Europe; but in the absence of information in this country as to their actual habitat, they were described, first by Zimmerman, on the continent, under the name of, Leucoprymnus cephalopterus, and subsequently by Mr. Zool. Eleven years later Dr. Mr. Zool. Templeton's description with that already laid before them by Mr.
The latter again becomes destitute of appendages, so that in this case at an early period four, and at a later only three, segments of the middle-body bear limbs. The fifth segment is still entirely wanting, whilst all the abdominal segments have also acquired limbs, and this one after the other, from before backwards. Zool.
Blyth informs me, with an exactly similar series of facts, as in the Portax picta, namely, in the male periodically changing colour during the breeding-season, in the effects of emasculation on this change, and in the young of both sexes being indistinguishable from each other. On the Ant. niger, see 'Proc. Zool. Soc. 1850, p. 133.
Different tones are emitted by the feathers of the different species when waved through the air; and the Scolopax Wilsonii of the United States makes a switching noise whilst descending rapidly to the earth. See M. Meves' interesting paper in 'Proc. Zool. Soc. 1858, p. 199. For the habits of the snipe, Macgillivray, 'History of British Birds, vol. iv. p. 371. For the American snipe, Capt.
