Bathyuriscus lio^iveUi Walcott, R. prodiirtiis H. & W. Plyclioparia pioclicnsis Wal- 

 cott, P. Kempi n. sp. This species is an allied form of P. siibcoronata, but has a pecu- 

 liar boss in front of the glabella. 



Zacantlioides typicalis Wale, Z. grnhatti n. sp., differs from Z. typicalis in general 

 shape of the head, the frontal margin and the genal spines.

On the systematie position of the Trilobites. 



Proc. Amer. Assoc, 1893, p. 365. 



Refers the Trilobites to a separate class, and regards them as being an older, more 

 primitive group than the Crustacea. Hence, the Trilobites probably were the first to 

 originate from the annelid worms, while the Crustacea aiose bv a separate line of 

 descent. 



Partridge (E. ^I. :Miss). Eehinocaris Wliidbornes (Jones & Wood- 

 ward) and Ecliinocaris slolieiifiis n. sp. 



Geol. Mag., Dec. 4, vol. 9, 1912, pp. 307-308, plate 17. 



The last species much resembles E. socinirs (Beecher) by the carapace and is much 

 longer in proportion to its width.
