Description. — Dorsal cup of moderate size, deep, sub-cylindrical. Infra- 

 basals (or proximal columnal) very small forming a pentagon very slightly 

 wider than the column, which is seen from its facet of attachment to have been 

 quadrate and pierced by four lateral canals. Basals five, equal, very tumid, set 

 nearly vertically and of a height equal to their width. Radials five, equal, 

 pentagonal, definitely tumid, of a height equal to two-thirds of their width ; their 

 straight upper margins forming an horizontal pentagon. Surface apparently 

 without ornament. 



Size of dorsal cup. — Height 15 mm. ; width 23 mm. 



Locality. — A defective dorsal cup and the remains of an infra-basal ring from 

 Wolborough are in the Museum of Practical Geology. 



Remarks. — While identifying these specimens with G. crassus, I should not have 

 ventured on separating them from the other imperfect specimens mentioned below, 

 except after the decidedly expressed opinion of so high an authority on Crinoids 

 as Mr. Bather. Of the figured specimen he remarks: "the verticality of the 

 basals, the slight swelling of the radials, and the apparently smooth surface 

 separate it from G. Schlotheimii, Steininger, aud G. elongatus, Goldfuss." 



Affinities. — C. inflatus, Schultze, 1 has a larger infra-basal ring, and only three 

 subsidiary canals in the column, but in general shape it is very similar. 



C. hieroglyphicus, Schultze, 2 has an elaborate ornamentation and a larger infra- 

 basal ring. 



C. scaler, Schultze, 3 is very similar, but seems more cylindrical, its infra-basal
