268 REPORT— 1882. 



latter pits are now closed, whilst the number of nodules brought up 

 from the Sunny Bank Pit is much restricted. The state of preservation 

 of the fossils is, however, most excellent, surpassing in this respect even 

 those from the famous Oldham and other Lancashire beds. 



So far as we have been able to study the fossils collected daring 

 the past year, we succeeded in throwing considerable light upon the 

 structure of Aster opliyllites (^Myriopliylloides') Williamsoni, upon Calamo- 

 stachys Binneana, especially in relation to the structure of its central 

 axis, upon a hitherto undescribed form of Kaloxylon, upon Lyginodendron 

 Oldhamium, and several other minor forms of plants, the structure and 

 affinities of Avhich are as yet imperfectly understood. Indeed, an enor- 

 mous amount of work remains to be done. We have already a very large 

 number of objects with the structure of which we are well acquainted 

 but the true botanical relations of which are entirely unknown to us. 

 In the case of some of these, persevering research has already enabled us 

 to ascertain those relations, and we doubt not that a continuance of that 

 perseverance will sooner or later enable us to throw a definite light upon 

 many of those whose botanical history is yet obscure. 



The following is a list of plant-remains from the Halifax hard 

 seam : — 



Lepidodendron Selaginoides. Kachiopteris insignis.

We have to express our indebtedness to those indefatigable woi-kers, 

 Messrs. Binns and Spencer, of Halifax, for valuable assistance given in 

 the investigation of the Halifax fossil flora.
