Fig. 194. — Calathium Anstedi. A fragment consisting of two individuals growing from 

 the same base. 



Description. — Turbinate, conical, expanding to the width of sixteen 

 lines in a length of two inches, several individuals sometimes growing 

 from the same base. Cup deep and narrow. Surface (and probably the 

 whole mass) reticulated with nearly square canals, of which there are 

 from four to six in the width of two lines, the apertures separated by thin 

 walls, about one-fourth of a line in thickness. The rows of pores ascend 

 the sides in straight lines, or nearly straight. The transverse rows are at 

 right angles to the vertical rows. 



Of this species only three specimens were collected, the best preserved 

 of which is represented by fig. 194. This consists of the lower portions 

 of two individuals which grew together. Length of the largest 2 inches ; 

 width at the upper extremity (broken off) 16 lines. The cup at this 

 place seems to be 6 lines in diameter, and the walls 4 lines in 

 thickness. 



Another specimen is 1\ inches across the larger extremity, and must 

 have been from 5 to 6 inches in length. 



Locality and Formation. — H, Pistolct Bay on Schooner Island, New- 

 foundland : Quebec group.
