20f> DEVONIAN FAUNA. 



From the type species of the genus, H. mespiliformis, Goldfuss, 1 sp., it is 

 still further removed. Its tegmen is lower, its dorsal contour is more angular, 

 the centres of its radials are much more produced, so as to give a stellate rather 

 than a simply pentangular section, while the sides of the ventral grooves are 

 curved instead of straight, forming with the insertion of the arms a figure of eight. 

 H. granatus, de Koninck, 2 from the Carboniferous of Yorkshire, is a more elongate 

 species, with a higher tegmen and much less stellate horizontal contour.

Description. — Dorsal cup small, rather elongate, deeply vasiform, oval in section. 

 Attachment of column extremely large. Basals three, rather high, and apparently 

 hexagonal in shape (one perhaps being pentagonal), forming a very deep cup. 

 Radials five, erect, quadrate, rather elongate ; no intercalated anal. Suture-lines 

 deep and broadly angular. 



Size of calyx. — Height 9 mm., width 9 mm., breadth 7 mm. 



Local ih/. — Wolborough. A single specimen is in Mr. Vicary's Collection. 



Remarks. — This little fossil is in an extremely bad state of preservation, and 

 difficult to decipher with any degree of certainty. 



[1 seems, however, certain that it has no intercalated anal plate, and therefore 

 docs not belong to the genus Hc.varrinns. 



On the oilier hand, it appears accurately to correspond with Wirtgen and 

 Zeiler' s and Schultze' s figures of Storthingocrinus fritillus, agreeing in all the
