SOME TERIIAKY FOSSILS FROM THE MIIKE COAL-FIELD. 13 



whether they are pointed or not. The carapace is somewhat 

 tumid and its whole surface is covered with irregular granules. 



Length 18 millim.; breadth 14 millim., at the broadest 

 part which is a little anterior to the hinder border. 



Of this genus, there are only two species described viz., 

 Hû7nolopsis Edicardsii Bell of the English Gault, and H. 

 Richardsoni Woodward (Some Podophthalmatous Crustacea from 

 the Cretaceous of Vancouver and Queen Charlotte Islands, Q. 

 J. G. S., May, 1896, vol. 52, p. 224, fig. 3) from the Cretaceous 

 of British Columbia. The Japanese species shows a decided 

 resemblance to the latter. 



Found at depth of 489 feet.

 PI. III. Fig. 3. 



This species also is represented by a single carapace with- 

 out appendages and may be characterized as follows : — 



Carapace roundly pentagonal, somewhat broader than high, 

 and uniformly flatly convex ; breadth 28 millim., height 24 

 millim.; regions mostly distinct and apparently smooth though 

 very small granules are discernible with a lens ; frontal margin 

 straight and furnished with a slight notch in the middle ; 

 epigastric lobes marked by a moderately large tubercle scarcely 

 distinct from the protogastric which are large and separated by 

 the long narrow pointed process of the mesogastric ; the latter, 

 is pentagonal in shape and is divided from the metagastric by 

 a shallow arched groove. Urogastric lobe indistinct ; cardiac 

 region pentagonal with a broad, shallow, median depression ;
