This list was for the most part prepared some time ago, 
but was laid aside to await the determination of few species. 
In the meantime, however, other work intervened. The list 
represents the results of a number of expeditions by zoolo- 
gists and collectors including Alpheus S. Packard in 1860 
and 1864. Samuel Henshaw in 1881, Lucien M. Turner in 
1882 and 1883, J. D. Sornborger in 1892 and 1897, A 
Stecker and J. D. Sornborger in 1899, Dr. C. W. Townsend 
and G. M. Allen 1906, Owen Bryant 1908 and 0. L. Austin, 
Jr., 1927. There is also added to the list a number of species 
more recently described by C. P. Alexander, J. R. Malloch, 
C. H. Curran, and A. L. Melander, the names of the col- 
lectors being given in connection with the species described.
