so as to give to the mass a more or less regularly reticulated appearance. 

 The apertures of the canals are round, oval, or quadrangular. The 

 cup seems to be deep. Structure of the partitions between the canals, 

 unknown. 



Calathium formosum. (N. sp.)

Fig. 192. — Calathium formosum. 

 Fig. 193.— C affine. 



Description. — The only specimen of this species, that has been collected, 

 is cylindro-turbinate, length 21 lines, diameter at the larger extremity 

 14 lines, and at the smaller 4 lines. The apertures are nearly 1 line 

 ■wide in the upper part, and half their own width distant from each 

 other. In the lower part they are somewhat smaller and closer together. 

 The longitudinal rows ascend obliquely, inclining a little to the left. The 

 transverse rows cross the others at right ansles.

 group.

Calathium affine. (N. sp.) 



Fig. 193. 



Description. — The specimen is about 9 hnes in length, and tapers from 

 9 lines in diameter at the larger end, to 3 lines at the smaller. There 

 are six transverse rows of tubes in three lines. The longitudinal rows 

 appear to be somewhat more numerous, but owing to the condition of 

 preservation they are not clearly seen. The fossil seems to be composed 

 of a series of rough transverse plates, but this is owing to the circum- 

 stance of the partitions between the longitudinal rows having been 

 destroyed. 



This species seems to be quite distinct from 0. formosum, in having the 

 tubes smaller and closer together, and in tapering more abruptly.
