A Petromyzon, or river laraprey of Tasmania, in spirits, presented

 to two long sharp teeth set upon its piston-like tongue. It has also 

 along the neck a very distensible pouch or bag directly under 

 its single nostril, which is situated centrally on the upper flat part of 

 the head, a little in advance of the eyes, over which the general 

 dermoid tegument is extended in a thin layer. 



Lieut. Clarke, R.E., presented from Mr. Strange, of Sydney, one 

 hundred marine, fresh-water, and terrestrial Shells, (amongst the

 Zealand.

 percha. 



Mr. H. Hull presented a preparation in spirits of the marsupium 

 of a Dasyurus viverrinus, having four foetus attached ; also the 

 cranium of a Dasyurus maculatus. 



Mr. Watchorn presented some pieces of shell of the egg of 

 the 3Ioa dinornis, having the striated, short, rough lines, or 

 depressions, characterising the specimens sent to England by Mr. 

 Mantel. 



The Secretary placed on the table a sample of bituminous Coal 

 from the estate of Mr. Chilton, at High Plains, about two miles 

 north of Hamilton. It occurs in a seam 4^ feet in thickness, and 

 was discovered in excavating a well for water in the farm-yard. The 

 superposed rocks consist of 30 feet of soft brownish sand-stone, 2 or 

 3 feet of a laminated yellowish-white clay, and 2 to 3 feet of blue 

 shale. There is immediately under the coal a few feet of blue shale 

 and slaty clay, which disintegrate rapidly on exposure. The sand- 

 stones and shales associated with the coal show themselves under the 

 greenstone on the same side of the Clyde near the bridge at Hamil- 

 ton, and again at various points in the direction of New Norfolk as 

 far down as the residence of Mr. Spode. 



Mr. Milligan placed on the table fragments from a silicified tree 

 imbedded in the sand-stone over this coal, and remarked that 

 fossilised wood is very abundant in the superior beds.
