not alter the evidence of the existence of the Primordial Fauna in 

 Newfoundland, for both genera are characteristic of it. The im- 

 portant point is this. From the occurrence of these fossils in the 

 same beds as the Paradoxides Bennetii, Salter, vre should naturally 

 look for something representing them in the slates at Braintree. And 

 I have the pleasure of stating that during the last summer I found a 

 fragment at Braintree, which I find to belong to the same genus as 

 the new specimens from Newfoundland. 



I have also found at Braintree a distinct fucoidal impression which 

 shows three branches, each about four inches long, but not sufficiently 

 well marked to aiford any evidence with regard to its nature. 



These two discoveries, although slight, show us the existence of a 

 variety of organic remains in the Braintree slates, and incite us to 

 further investigations. And I hope that the next summer will not 

 pass without further developing their riches, and affording us some 

 new facts with regard to the Primordial fauna of the eastern portion 

 of America. 



On the gexus Raphidophora, Serville ; with descriptions 



OF FOUR species FROM THE CaVES OF KENTUCKY, AND FROM 



THE Pacific Coast, By Samuel H. Scudder. 



In 1839, Serville, in his Histoire naturelle des Orthopteres, charac- 

 erized, among the Locustariag, the genus RaphidopJwra, from a single 

 species from Java, R. picea. Burmeister in the previous year, had 

 described the same insect, in his Handbuch der Entomologie, under 

 the specific name Joricata, and placed it in the genus Phahmgopsis of 

 Serville, together with other species of either genus, separating them 

 from one another as different sections of the same genus ; he, how- 

 ever, discovered his mistake before the completion of his work, and 

 in the appended corrections, notices " that the sptecies of the first 

 section appear to belong to the following family," (Gryllodea ;) and 

 subsequently (Germar's Zeltschrift fiir Entomologie, ii. 72), he asserts 

 that his second section, in which occurs his P. loricala, is identical 

 with Serville's genus Raphidophora. 



Misled by Burmeister's error, in the body of his work — where he 

 describes one species "P. lapidicola " from the United States, without 

 much doubt, identical with the well-known R. macidata of Harris, — 

 and overlooking the correction made by Burmeister himself in his 

 appendix and in Germar's Zeitschrift, and probably also noticing the 

 strong general resemblance of P. longipes, of Central America, as 

 figured in Serville's work, to our " wingless crickets," all the species 

 found with us have been referred by American entomologists to the 

 genus Phalangopsis. A careful examination will prove that they all 

 belong to the genus Raphidophora, no species of Phalangopsis having 

 been vet described from the United States.
