es vielmehr darin mit gewöhnlichen Höckern zu thun, wie sie gerade 
innerhalb der Arrenurus-Gattung gar nicht selten auftreten. Ich 
werde demnächst Gelegenheit haben, auf diesen Gegenstand ausführ- 
licher zurückzukommen. 
Ebenso vermag ich bei Arrenurus forpicatus C. J. Neuman bei 
keiner Lage des Männchens einen Petiolus zu erkennen, den Piersig 
bei genannter Art aufgefunden haben will (daselbst p. 414) und den 
er als klein und meißelförmig bezeichnet. Ein so beschaffenes Gebilde 
beobachte ich allerdings in der muldenförmigen Vertiefung auf dem 
Körperanhange, das indes keineswegs ein Petiolus ist, sondern ein 
dem Panzer aufgewachsenes Chitinband, das zu einer festeren Ver- 
bindung des nur hier auf einer kurzen Strecke mit dem Bauchpanzer 
verwachsenen Rückenpanzers mit dem vorhergehenden dient.

20th December, 1892. — A letter was read from Dr. A. B. Meyer, 
of Dresden, C.M.Z.S., respecting the occurrence of a Monkey (‚Semnopithe- 
cus nemaeus) in Hainan. — A communication was read from the Rev. T. R. 
R. Stebbing, entitled »Descriptions of Nine new Species of Amphipodous 
Crustaceans from the Tropical Atlantic«. This communication contained 
descriptions and figures of some new Hyperidean Amphipoda collected by 
Mr. John Rattray, when on board the »Buccaneer« at the beginning of 1886. 
The specimens had been taken in the tropical Atlantic off the west cuast of 
Africa by a series of »tow-nettings« carried on at the expense of Dr. John 
Murray and Mr. J. Y. Buchanan, — Dr. Hans Gadow, F.R.S., gave an 
account of the remains of some gigantic Land-Tortoises and of Didosaurus 
recently discovered in Mauritius, along with the bones of the Dodo described 
in a previous communication by Sir Edward Newton and himself. The re- 
mains of the Tortoises were referred to Testudo indica, T. triserrata, T. inepta, 
and to two new forms proposed to be called 7. Sauzieri and T. Soumeirei, the 
latter being possibly related to the gigantic Tortoises of Aldabra. Along 
with these Tortoises were found numerous bones of the extinct Lizard, 
Didosaurus mauritianus, of which an account was also given. — Mr. F. E. 
Beddard, F.R.S., gave descriptions of some new species of Earthworms 
from various localities — belonging to the genera Octochaetus, Acanthodri- 
lus, Benhamia, Microdrilus, Perionyx, Moniligaster, Notykus, Trichochaeta, 
and Z/yogenia. Of these nine genera Octochaetus, Microdrilus, and Ilyogenia 
were characterized as new to science. — Mr. R. H. Burne, F.Z.S., read 
a note on the presence in the Common Hag (Mywine glutinosa) of a branchial 
basket, which had not been previously recognized in this fish, though already 
described in the Larger Hag (M. bdellostoma). — P. L. Sclater, Secretary.
