expanded behind the sacrosciatic notch and united with the ilium, as 
it very generally does in carinate birds. It is very desirable that this 
part of the skeleton of Archeopteryx should be figured again. 
The scapula has a distinct clavicular process, as in carinate birds ; 
and it seems to be pretty clear that the scapula had that twofold 
angulation upon the coracoid which is characteristic of the Carinate. 
The glenoidal end of the coracoid is unlike the corresponding part 
of that bone in any of the Ratite; but it is more like that ofa 
Pterodactyle than that of any carinate bird which I have met with. 
It is less prominent (and the counterpart shows that this shortness is 
not the result of fracture) than in any recent bird, provided with a 
strong furculum, with which I am acquainted. In fact, in its form, 
and strength relatively to the shoulder-girdle, the so-called “ fur- 
culum ”’ appears to me to be the greatest osteological difficulty pre- 
sented by Archeopteryx. I prefer waiting for the light which will 
be afforded by another specimen to the indulgence of any speculation 
regarding this bone ; in the meanwhile, I by no means wish to deny 
that appearances are strongly in favour of the interpretation which 
has been put upon it. 
In conclusion, I may remark that I am unaware of the existence 
of any ‘‘law of correlation’’ which will enable us to infer that the 
mouth of this animal was devoid of lips, and was a toothless beak. 
The soft tortoises (Trionyzx) have fleshy lips as well as horny beaks ; 
the Chelonia in general have horny beaks, though they possess no 
feathers to preen ; and Rhamphorhynchus combined both beak and 
teeth, though it was equally devoid of feathers. If, when the head 
of Archeopteryz is discovered, its jaws contain teeth, it will not the 
more, to my mind, cease to be a bird, than turtles cease to be reptiles 
because they have beaks. 
All birds have a tarso-metatarsus, a pelvis, and feathers, such, in 
principle, as those possessed by Archeopteryxr. No known reptile, 
recent or fossil, combines these three characters, or presents feathers, 
or possesses a completely ornithic tarsometatarsus, or pelvis. Compso- 
gnathus comes nearest in the tarsal region, Megalosaurus and Igua- 
nodon in the pelvis. But, so far as the specimen enables me to judge, 
I am disposed to think that, in many respects, Archeopteryz is more 
remote from the boundary-line between birds and reptiles than some 
living Ratite are.

Size of Fetus of the Pilot Dolphin. 
Mr. Epwarp GEerrarp, junior, extracted the foetus from an adult 
female of Globiocephalus svineval that was thrown ashore at the 
Firth of Forth. The female was 12 feet, the fetus 3 feet long. 
The head of the foetus is very globular ; and the beak is well marked, 
but very short.—J. E. Gray. ;
