zugehen, daB vom Stolo prolifer der Amme Knospen nicht aber Ur- 
knospen wie beim Doliolum abgehen und daß der Bau dieser Knospen 
ein ganz anderer als der der Doliolum-Knospen ist. Das führt zu dem 
Schlusse, daß auch der Stolo prolifer der Anchinia-Amme anders als 
der Stolo prolifer der Doliolum-Amme gebaut ist.

Aug. 29th, 1883. — 1) On a fossil Calvaria. By Charles De Vis, 
B.A. The writer gave a full and minute description of this fossil, which 
consists of the parietal and the upper part of the occipital bones. It is re- 
markable for the great prominence of the occipital spine, and thickness of 
the parietals, which, though only four inches in length by three in width, 
have an average thickness of nearly three-quarters of an inch; the bevel of 
the coronal suture being thirteen lines in depth. He was inclined to refer 
this singular form to some extinct Sirenian, living in fresh waters, and of a 
much lower degree of development than those now existing. — 2) Remarks 
upon a skull of an Australian aboriginal from the Lachlan district. By Baron 
N. de Miklucho Maclay. The skull which was found by Mr. C. Hors- 
ley of Gunningbland Station, in the Lachlan district, is remarkable for the 
formation of the occipital bone. ‘The superior curved line with the external 
occipital protuberance, forms not a line but a very prominent occipital crest, 
and the hindmost part of the skull is not the convex part of the superior 
portion of the occipital bone, but this occipital crest. The thickness of the 
bone between the external and internal occipital protuberances is 21 mm. 
The skull is also remarkable as being very dolichocephalic, the index of the 
breadth being 66.8. — 3) Professor Stephens exhibited a living example 
and photographs of the remarkable New Zealand Hatteria (Sphenodon, or 
Rhynchosaurus) punctata, brought to Sydney by W. Knight, Esq., from 
Karewa Island, Bay of Islands, 6 miles from Tauranga. Here this lizard 
lives in association with the Mutton birds, whatever these may be, in great 
numbers. Whether this association is based upon pure friendship maybe 
doubtful. The affinities of this animal are, according to Huxley, with the 
Triassic Hyperodapedon, which it resembles in many points, as for example 
the singular action of the lower jaw with its single row of teeth, cutting bet- 
ween two rows in the upper, one row being in the maxillary, the other in 
the palatine bones, or rather, both being carried on a plate in which both 
bones are fused. The amphicoelian character of the centra is also an impor- 
tant point as connecting this with lower or Archiac forms. Owen de- 
scribes the osteology of this creature, under the name Rhynchosaurus, in 
Vol. 1, Anat. Vert., p. 57, 154 etc., reckoning it as a New Zealand Gecko. 
Günther has also described it under the name of Aatteria, Phil. Trans., 
1869. Mention is made of it in the earliest notices of New Zealand; and 
it appears to have been rather an object of dislike or superstitious fear 
among the Maories. The pigs however, as aliens, feel neither dislike nor
