mi. ,1. W. DAWSdX ON EinX'T THEES CONTAINING ANIMAL 



Wifli tlioso reninins are ii i\\v bony sojilos ditt'erent from tliosn of iiny other species 

 found in these ti'ces, iuul more resemhlinj; scales of Ganoid Fislies. They are soine- 

 wliat rectangular in I'orin, enanielicd on the surface and beautifully sculptured with 

 waving lines. 



In the same tnuik weic found some teeth and bones referable to ITf/h n 



D<nrso)ii, and it is not iin|)iissible that the remains above referred to may have 

 belonged to some creature devoured by that animal, and which would not otherwise 

 have obtained admission to the interior of an erect tree. The tree itself had been 

 removed by the sea, all but a little of the base, and this was in a very nnsatisfiictory 

 state, so that ddubt might even exist as to the limit between the deposit in the 

 interior of the tree and that under its base.

h\ tree No. lO were foimd a few teetli and bt)nes which do not seem referable to 

 any of the genera above named, though pretty certainly belonging to a member of the 

 group of Mirrosauria. 



A fragment of a jaw 1 centimetre in length has ten cylindrical teeth, simple and 

 smooth, with large pulp cavities and rounded regularly at the apices. With these 

 are four vertel)r;e of the usual type, measuring together I centimetre. Fragments of 

 cranial bones also occur and are obscurely pitted. There is also what seems to be the 

 shaft of a limb bdiie and a few nval scales. A flat, somewhat rhombic bone with a 

 style at one side may possibly be a thoracic plate or possibly a ])ara.s2»henoid. 



The material is too scanty fir any satisfictory descrij)tion of this animal, but I have 

 named it provissionally Ainhli/whin pruldemntk'tim.

This occui's in several of the tiees. not in masses of regular form lint in indetiitite 

 l)atches. It is of a gray or butf colour, and usually highly calcareous. It is often 

 tilled with comminuted bones not determinable ; but evidently of small liatrachians 

 and prol)al)ly of Ili^'Jowihius. Fiagnients of chitinous matter also abound in some of 

 the coprolitic masses. In most cases they seem to belong to [Millipedes, but in a few 

 examples insect remains occur. They are not determinable ; but in one specimen was 

 a well-preserved Iragment of a head apparently of a small neuropterous insect showing 

 one of the compound eyes. Fragments of shells of Pupa are fiund in and near some 

 of the coprolitic masses, and I think it i)robable that these ]ndmonates fn-med a part 

 of the food of some of the IJatrachi.in species. 



Some doubt nuist of course e\i?.t as to whether the siibstances contained in the 

 coprolite represent the ordinary tood of the amj)hil)ia or only that to which they had 

 access while imprisoned in the ere.t tri'cs. The fa.'ts so far as thev go would indicate
