sont réunis non au-dessus du muscle, mais au-dessous. Ce dernier 
phénomène a lieu chez tous les Cirripèdes, excepté chez l'Zbla. 
C’est pourquoi on peut considérer le muscle adducteur des Cru- 
stacés (excepté les Cypridinides) malgré sa position chez les Cirripèdes, 
comme appartenant au système des muscles ventraux.

April 26th, 1893. — 1) Note on the Occurrence of the Sanderling 
(Calidris arenaria) in Borneo. By Henry Seebohm. (Communicated by 
Dr. E. P. Ramsay.) — 2) Revision of the Australian Amarygmides. By Rev. 
T. Blackburn, B.A., Corr. Mem. Part II. — The Genera Chalcopterus 
(continued) and Amarygmus. — 3) Botanical. — 4) Notes on the Synonymy 
and Distribution of some old-described Australian Mollusca. By John Bra- 
zier, F.L.S., C.M.Z.S. The author points out that Swainson’s genus Astele 
(1854) = Eutrochus, A. Ad. (1863): that Turbo undulatus, Martyn, and its 
varieties are confined to Australia and are not found in New Zealand; that 
Turbo Gruneri, Philippi (1848), = Turbo circularis, Reeve (1848); that 
Murex australis, Quoy and Gaimard (1832), = Murex palmiferus, Sowb. 
(1840); that Murex umbilicatus, Tenison-Woods, = Murex scalaris, A. Ad, 
non Brocchi; and that Helcioniscus tramoserica, Martyn, the locality for 
which was given by Martyn as the North-West coast of America, is only 
found in Tasmania and Australia. — 5) Geological. — Mr. John Mitchell 
contributed a Note on the discovery of a bone-deposit exposed in the bank 
of a newly-formed water-course on the Terrible Vale Run, near Kentucky 
Railway Station, between Tamworth and Armidale, in the county and parish 
of Sandon. Further exploration of this deposit is promised; but so far there 
have been met with bones and teeth, all in a very friable condition, of kan- 
garoos of species possibly both extinct and living, as well as what would 
appear to be two small carnassial teeth of Thylacoleo. The altitude at which 
the deposit occurs, the physical conformation of the country, together with 
the fact that the deposit is covered by ten feet of alluvium consisting chiefly 
of granite detritus, combine both to make the discovery of considerable in- 
terest, and to render it desirable that its geological age should be determined 
with exactness. — Mr. Froggatt exhibited specimens of a crane-fly (Family 
Tipulidae) and of a bug (Family Reduviidae), showing the mimetic markings 
of the latter, which no doubt enable it to catch the former. — Mr. Trebeck 
exhibited an orthopterous insect (Phibalosoma) from Fiji; and a scorpion 
irom Queensland. — Mr. Fletcher exhibited for Mr. J. H. Rose, of Wa- 
rialda, two interesting frogs (Limnodynastes ornatus, Gray, and Heleioporus 
pictus, Ptrs.), and made some remarks on their distribution. He also showed 
a living cystignathoid frog of large size but retiring habits, at present un- 
described, from the neighbourhood of Sydney, with which he proposed to 
deal on a future occasion.
