Woodward, H. — On the Structure of Trilobites- (Geol. Magazine, 

 3d Decade, February, 1884, vol. i, No. 2, pp. 78, 79. London.) 

 A reproduction of the author's views on the appendages of trilobites, 



and Asaphus platyceplialus Stokes, in particular, as published in 187 L in 



the Geol. Magazine, July, pp. 289-294, pi. viii. 



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

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

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

Reproduces Mr. John Mickleborough's figures of Asaphus megistos 

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

 of Galyit,ene senaria, tliat 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. in, pp. 279-281.)
