1 70 RATHBUN 



while the fissure next the outer tooth is larger than in the typical form ; 

 the first tooth of the lateral margin is nearer the posterior tooth than it is 

 to the orbital tooth; the surface is more uneven, and more coarsely 

 granulate. The legs are absent. I think the differences are not those of 

 age, and indicate a distinct species, to which, however, I hesitate to give 

 a name on account of the poor condition of the specimen.
