200 DEVONIAN FAUNA. 



Locality. — Lummaton. There is a small but fine calyx and a detached radial 

 in the Lee Collection in the British Museum, and a much larger but very indistinct 

 cast in my Collection. 



E( marks. — Though the material at hand for describing this form is so scanty, 

 it presents some points which suggest specific or possibly generic distinction. 

 Thus the trilobate surface of the base indicates a rather curiously shaped column, 

 while the fact of there being apparently seven plates resting on the basals seems 

 remarkable. Of these, five are ordinary radials ; the sixth, though of similar 

 size, is of decidedly irregular shape; while the seventh is much smaller, elongate, 

 hexagonal, and seems to occupy the same relative position as anal X . 



Should the arrangement of the anal plates prove (as is certainly possible) an 

 accidental malformation, it would present such an approach to H. elongatus, 

 Goldfuss, 1 sp., or still more to H. piriformis, Schultze, 2 as to make it possible that 

 it might be a variety of one of them, though the former is distinguished by its 

 coarse and more confluent ornament, and the latter by its much longer basals. 

 To Eifel specimens of the former in Mr. Lee's Collection it is certainly very like, 

 and in Mr. Bather's view probably identical.
