devoted to beautiful illustrations of the Kimberly spear-heads, repro- 
duced by heliotype process from drawings made by Mr. G. H. Barrow. 
A bibliography of palceozoic Crustacea from 1698 to 1889, including a 
list of North American species and a systematic arrangement of genera. 
Ey Anthony W. Vogdes. ( Bulletin No. 63, U. S. Survey, 1890, 8vo. 
pp. 177.) 
Captain Vogdes' long acquaintance with the literature of the trilo- 
bites and other Crustacea has served to produce a very valuable aid to 
students of paleozoic Crustacea, this bulletin serving them as a work- 
ing hand-book and guide to the original literature. The trilobites are 
arranged into 81 genera. The author enumerates 682 species, and gives 
-a systematic classification of the eighty-one genera, which he arranges 
in alphabetic order giving references to all the specific descriptions. 
The LOWER TAOONIO is represented by the following genera : 
Olenellus, Agraulos strenuus, Atops, Ellipsocephalus, Bathyno- 
tus, Protypus, Liostracus, Ptychoparia adamsi, P. fitchi, P. misera, 
P. sub-coronata, P. teucer, P. vulcanus, etc., Agnostus, nobilis, A. 
inter str ictus, A. desideratus, Microdiscus, Avalonia, Oryctocephalus 
Zacanthoides spinosus, Z. typicalis, Solenopleura bombifrons, S. nana, 
S. harveyi, S. hoivleyi, Anomocare (? ) j)orvw?)i ; in Newfoundland, 
Canada, Vermont, New York, Nevada and Utah. _ 
The 2d fauna, or Paradoxides zone, appears in Newfoundland, Massa- 
chusetts and New Brunswick ; it contains the following genera: Para- 
doxides, Agraulos affinis, A. socialis, Liostracus tencr, L. ouun- 
gondianus, Ptychoparia, linnarssoni, etc. Solenopleura bombifrons, S. 
communis, S. robbii, S. acadica, Agnostus acadicus, A. regains, A. par- 
titus, A. vir, A. tessella, A. umbo, A. obtusilobus,A. acutilolms, etc. Con- 
ocoryphe baileyi, C. elegans, C. ivalcotti, Ctcnocephalus (Hartella) 
matthewi. 
The UPPER TACONIO, comprising the 3rd or Olenus zone is only rep- 
resented in America by Olenus ulaliensis, the 4th fauna or ParaboUna 
and Peltura zones is not known in America. The Upper Taconic in- 
cludes the Olenus, ParaboUna and Dikelocephalus zones. 
The fifth fauna, or Dikelocephalus zone is well represented in the Que- 
bec group of Canada, also in Wisconsin, Nevada, Utah, Texas, etc.; it 
contains the following genera: Anomocare, Bathuyrus, Chariocepha- 
lus, Dikelocephalus, Iliaenurus, Ptychoparia, etc. 
The following list gives a synopsis of the genera appearing in the 
Taconic, followed by a number of species in each genus. Afflaspis
