Woodward, H. — Notes on the Appendages of Trilobites. Note to ac- 

 company three woodcuts of Asaphus megistos, a Trilobite discovered 

 by Mr. James Pugh, near Oxford, Ohio, in the upper portion of the 

 Hudson River group. (Geol. Magazine, 3d Decade, April, 1884, vol. 

 I, No. 4, pp. 1C2-1G5. London.) 



Rei)roduces Mr. John Mickleborough's figures of Asaphus megistos 

 with a few remarks. He suggests, concerning Mr. Walcott's restoration 

 of Cahjntene senaria, that the last seven pairs of appendages belonging 

 to the pygidium were more probably lamelliform branchigerous append- 

 ages as in Limulus and in living isopods. (See Mr. Walcott's article 

 in Science, vol. ill, pp. 279-281.)
