The author proposed a new genus Hughmilleria for a small form, which from its 

 general appearance in many ways suggests the genus Eurypterus, but a study of its 

 structure shows it to be closely related to Pterygotus. 



The author describetl Hui^hmUlerin snrinlis nov. and var. rohusirt nov. var. A new- 

 species of Eurypterus is included under the tiaine nf E. pitfsforJrusis. which closely re- 

 sembles E. lacustris, approximatelx' of the same size, also in the position and shape of 

 the eyes. The posterior portion of the cephalon flares out in E. pittsfordcnsis, or at 

 least broadens out in a h\perhnlic cur\e, while E. liuustris is marketl by the nearly 

 parallel sides of the cephalon. 



The author also describes P/rryirotus rnnuronis's now

 series in Missouri and Illinois, part one.

The author describes Prochts princeps n. sp. This rare specimen from the Thebes, 

 Illinois, has a glabella resembling that of /'. drtrnn'tnatus Foerste, and differs but 

 slightly from the Edgew(K)d species. From the C liiardeau limestone, Shumard, 

 Geol. Mo., 1855, p. 198, gives the name of Prarlus drprrssus to a species without figure 

 or description. This is not the /'. drprrssus W'eller, Pal. N. J., vol. 3, p. 249. 



The author also describes C.yphtispis t^irdrdraurnsis ShuiTiard. .Iriddspis llolli 

 Shumard. Enrr'niurus deltoidrus Shumard and Calymrnrur duhia n. sp., which re- 

 sembles C.alymmrne platycephala Foerste. 



From the I''dge\vood series of Illinois the author ilescribes: 



Proetus determinatus Foerste, described as 15atlivurus Foerste in the Bull. I.ab. ]")en. 

 Univ. vol. 1, p. 103, pi. 14, fig. 5, 1885. 



Cyphospis intermedia Weller, and Metnpnlirluis brevireps \-ar. rlintntiensis Foerste. 



Dalmanites Dauai Meek and Worthen. 



The species resembles I), limulurus Cireen, but somewhat larger. 



From Channalion, Illinois, the author ilescribes Prnrlus cliaiiiialinncnsis \A'cller. It 

 has a more prominent glabella and deeper glabella finrows than /*. determinatus 

 Foerste.
