INDICES TO PARTS I, II, AND III 
SYSTEMATIC INDEX OF THE NEW NAMES PROPOSED BY B. D, 
WALSH AND BY WALSH AND RILEY. 
[The Walsh and Riley names are followed by W. & R. The first number following 
the name refers to the number of the paper in the list, the second to the page where 
the species is first described. As is well known, the Walsh collection was destroyed 
in the Chicago fire in October, 1871. A few of the types sent to Drs. Hagen and 
Riley are in the collections of the Museum of Comparative Zoology at Cambridge 
and the National Museum at Washington. Those at Cambridge are indicated by a *, 
those at Washington by **.]
