and long, jointed, superior spinners it would be impossible to 

 relegate the specimen to the genus Atypus with absolute 

 authority. Neither would one be warranted in characterizing 

 a new genus by the absence of eyes and spinners, since these 

 organs were doubtless present, but have simply failed to 

 impress themselves upon the matrix. I have therefore felt 

 compelled on the one hand to propose a new generic place for 

 this fossil, and on the other to present no sharply defined 

 generic characteristics. Indeed, it must be admitted that 

 besides expressing the general facies of the fossil, as above 

 described, the generic value of the name Eoatypus consists 

 largely in assigning the specimen rank as a fossil spider. 



On one side portions of all the four legs are preserved, the 

 first three showing the articulations at the trochanter, femur, 

 and patella. The second leg shows also the patella entire, 

 indicating the articulation with the metatarsus. On the other 

 side a portion of the femur of the first leg is shown with the 

 patella and its articulations. Both hind legs are represented 

 by the apical parts of the femora. 



The horizon from which this new fossil was obtained is 

 that from which most European fossil spiders have been 

 taken, viz. the Eocene Tertiary. It is also that from which 

 have come our American Aranead fossils as recently studied 

 by Mr. S. H. Scudder from specimens collected at Florissant, 

 Colorado.
