Epiphyse surl’opisthotique. L’apophyse parotique, Hux- 
ley, porte, à l'endroit où elle rencontre le Quadratum, — par consé- 
quent, dans la région opisthotique, — une épiphyse. Que cette épi- 
physe ne peut être confondue avec le ptérotique 17 ressort suffisamment 
du fait que ladite ossification ptérotique existe simultanément avec 
l’épiphyse. 
M. Albrecht me dit qu'il est enclin a identifier mon épiphyse 
sur l’opisthotique avec une épiphyse qu'il a découverte, il y a quelques 
années, sur l’apophyse mastoïde d’un crâne d’ Ursus labiatus Blainville 
(No. 3244 de l’Institut anatomique de Koenigsberg). 
Epiphyse sur le Quadratum. Jai vu, à l'extrémité dorsale 
du Quadratum, une épiphyse. Même observation que plus haut rela- 
tivement au ptérotique.

15th January, 1884. — The Secretary read a report on the addi- 
tions that had been made to the Society s Menagerie during the month of 
December 1883. — The Secretary exhibited, on the part of Mr. H. Whi- 
tely, an immature specimen of the Night-Heron (Nycticorax griseus), which 
had been shot in Plumstead Marshes, Kent, in December last. — A com- 
munication was read from Mr. J. C. O'Halloran, Chief Commissioner 
and Police Magistrate for Rodriguez, accompanying a specimen of a large 
Lizard found only in that island, and very rare there. The specimen had 
been identified by Mr. Boulenger as Phelsuma Newtoni, belonging to the fa- 
mily Geckotidae. — Sir Joseph Fayrer exhibited some additional specimens 
of the horns of Deer gnawed by other Deer, in confirmation of previous 
remarks on the subject. — Canon Tristram, F.R.S., exhibited and made 
remarks upon some specimens of species of the genus Pachycephala, which 
appeared to have been ignored or wrongly united to other species in a recently 
published volume of the Catalogue of Birds of the British Museum. — Mr. 
W.F.R. Weldon read a paper in which he gave a description of the pla- 
centa in Tetraceros quadricornis. The author showed that this placenta is in- 
termediate between that of Moschus and that of the typical Bovidae, having 
few cotyledons with diffuse vascular ridges between them. Associated with 
this primitive character is a uniserial psalterium. — A second paper by Mr. 
Weldon contained some notes on the anatomy of a rare American Monkey, 
Calhthrix gigot, which had recently died in the Society" s Gardens. The author 
gave a description of the external characters, and the principal viscera were 
compared with those of C. moloch and of Mycetes. — A communication was 
read from Mr. E. J. Miers, F.Z.S., giving an account of a collection of 
Crustacea from the Mauritius, which had been forwarded to the British Mu- 
seum by M. V. de Robillard. In the collection was an example of a new
