New Species from Lower Carboniferous of Bally casfle. 21 



that there once existed ice-masses that left their load and tracks all 

 over N. China. ^ Had this celebrated author been able to collect 

 more evidence, and so to present his case in a more forcible way than 

 a mere passing remark, it would have drawn, as it fully deserves, 

 nmch more attention from the scientific public ; and would have 

 given impetus at least to those keen observers that have conducted 

 many a fruitful scientific exploration into various parts of the 

 country since Richthofen's time. But when the author remarks 

 that the Chinese ice-sheets descended from the Great Himalayan 

 Range, his inference seems to have been extended a little too far ; 

 for the author himself mentions no fact in support of such 

 a hypothesis, nor are we able to gather any evidence pointing to 

 that effect if we turn to the reports contributed by many brilliant 

 explorers like Bogdanovitch, Rovorovsky, Obrutchov, Loczy, and 

 others. It may be safely said that we are as yet thoroughly ignorant 

 as to the origin and the movement of the Chinese ice-sheets or ice- 

 rivers. Any attempt made with the object of throwing light upon 

 this subject must, for the present, be directed towards the field.

 (PLATE III.) 

 TN the course of collecting in the Ballycastle coalfield, the species 

 -■- described in this note were obtained. Details of the associated 

 fauna will be found in the forthcoming memoir of the Geological 

 Survey of L'eland relating to the district. It is only necessary to 

 mention here that the beds from which the present material comes 

 are, in the memoir, referred to a T>2 horizon. 



Ci/pricardella nuculoides, sp. nov. (Plate III, Figs. Irt-c and 2.) 

 The form and dimensions of this shell are sufficiently shown by the 

 figures. It will be noticed that there is no oblique ridge from the 

 beak to the postero-inferior angle, and the posterior end is not 

 truncate. The ornament consists of sharp, raised, concentric ridges. 

 A left valve with hinge exposed (Fig. 2) shows two cardinal teeth,
