‘erowth’ and to have undergone some marvellous rearrangements 
of the particles while in the solid condition. So far as he knew, 
no one had previously attempted to classify the different patterns, 
nor had anyone, except Mr. Wickham King, in his work on 
«Permian Fossils, offered any theory as to the formation of this 
cellular structure in the Magnesian Limestone.

«Qn the Skull of a Chiru-like Antelope from the Ossiferous 
Deposits of Hundes (Tibet).’ By Richard Lydekker, Esq. 
Twenty years ago the Author proposed the provisional name of 
Pantholops hundesiensis for an extinct species of antelope typified 
by an imperfect skull figured in Royle’s ‘Botany ete. of the 
Himalaya Mountains, pl. iii, fig. 1. The specimen is in the 
Museum of the Geological Society, and an examination has con- 
firmed the original determination. The skull, although of rather 
smaller dimensions, comes very close to that of the existing chiru 
(Pantholops Hodgsont) of Tibet in general form of brain-case, in 
she strong ridges marking the upper limits of the temporal fossz, 
and in the contour of the occipital surface. The horn-cores have 
the same highly elliptical cross-section, and the same general 
setting-on and upright direction. The fossil apparently came from 
the horizontal deposits of Hundes, and its age is probably not 
greater than Upper Pliocene.

On Apus and Branchipus from Armenia. By H. O. Cavarier. 
Mr. Frrrx Oswatp recently collected some speeimens of Apus 
cancriformis and Branchipus stagnalis in some pools on the Bingol 
Dagh, in Armenia, at a height of 10,000 feet ; they are now in the 
British Museum, where, through the kindness of Professor F. Jeffrey 
Bell, I have had an opportunity of examining them. It is interesting 
that the proportion of males is unusually large: of Apus there is 
one male and one female, of Branchipus two males and six females. 
As Crustacea at sueh heights are rarely discovered, I think it 
worthy of record that these are practically identical with the common 
European species, though this is only in accordance with the results 
of Grube * on Apus from Lake Baikal and of Gaerstaecker ft on 
the Siberian Branchipus; but there ave some slight differences 
in the appendages. When sufficient material has been collected a 
table of the variations of Crustacea at different altitudes may be of 
considerable interest.
