less coéxtensive, especially after the removal from them of the Coty- 
losauria. 
The affinity to the Mammalia which Professor Owen saw in the hu- 
merus, and which I have pointed out in the skull, shoulder-girdle, fore- 
limbs, and hind-limbs and foot, is confirmed by Seeley’s researches. 
He finds a fore-limb and foot of what he believes to be a veritable 
mammal inthe same beds of the Cape, which is the subject of his 
third memoir, and which he refers to a species and genus under the 
name of Zheriodesmus phylarchus. The probability of this determina- 
tion being correct appears to me to be strong. The humero-cubital 
articulation is mammalian, and there is nothing in the pes forbidding 
the association. Dr. Bardeleben thinks that it has a prepollex with 
metacarpal and phalange. On this interpretation there is one large 
os centrale. 
We are gratified to learn that Dr. Seeley has accepted the position 
of Director of the Geological Survey of the Cape, and we feel sure 
that important discoveries await him there in his chosen field.

Devonián.—The Geological Magazine for January has some pretty 
full notes by Dr. R. H. Traquair upon some Devonian fishes from 
Scaumenac Bay and Campbelltown, now contained in the Edinburgh 
Museum. Most of the species have been described by Professor Whit- 
eaves, but these notes give much information upon the Ctenodontide, 
Cephalaspide, Acanthodide, Holoptychide, Pleurichthiidz, Paleon- 
iscidze, etc. ' 
Mesozoic.—S. Nitchin gives an account of the Jurassic beds of 
the Himalayas and Middle Asia. The principal development of the 
Jurassic in the Himalayas is on the north-east slopes of the south- 
ern crystalline chain near Spiti and Niti, where dark crumbling shales 
known as the Spiti shales rest on beds said to be Lias and Rhætic. 
Phosphatic concretions are abundant, and ammonites plentiful. Opin- 
ions differ about the parallelism of the horizon, but it is generally 
thought that these shales are of the age of the Kelloway and Oxford 
clays. Nitchen thinks them more recent, and states that their fauna 
approaches nearest to that of the Tithon and Kimmeridge. The fauna 
of the Russian Jurassic is near that of Cutch. 
Professor A. Pavloff believes that the Upper Jurassic of Russia is so 
near that of England that a common classification might be adopted. 
He describes as new three species of Cleostephanus, viz., C. baki, 
swindonensis and stenomphalus.
