Poteriocrinus xetti.erothaxcs, S. A. Miller, 1882, Jour. Cin. Soc. Nat. Hist. 

 vol. 5, Up. Held. Gr. [Ety. proper name.] 



The author has been informed that Mr. J. M. Clarke has described a new genus 

 and three new species of Phillocaridae, which will probably appear in the Am. Jour. 

 Sci. & Arts, for February, 1833, viz: Dipterocaris pescervae, D. pennidsedali, and 

 D. procne— all from the Chemung. 



Prof. E. YV. Claypole says there is little or no classic ground for printing ce in the 

 beginning of the second part of a compound word, such as ruycestriatus. It should be 

 rwjistriatus. An exception occurs when the first part of the word is merely a prefix, 

 as in sitbcequalis. That nebraskensis should be written instead of nebrascensis , as there 

 is no ground for using the c instead of k. And that the generic name Chariocephalus 

 should be written Charitocephalus.
