brings the Iowa fauna into relationship with the Chemung and Cats- 
kill of Pennsylvania on the one hand, and with the Waverly of Ohio 
on the other. Nevertheless the different aspects of these faunas when 
compared with one another are very considerable. Through Ptyctodus 
calceolus the fauna is related also to the Hamilton of the Mississippi 
valley. The abundance of this form, and the absence of all other 
Elasmobranchs is a surprising dircumstance. However, it is more 
than likely that further search will bring to light many forms which 
we should naturally expect to find in rocks of this horizon." 
Some of the further descriptions of the Iowa fishes are contained 
in an article by Dr. Eastman, in the American Naturalist for July. 
1898 (vol. XXXII, pp. 473-488) in which is considered the Dentition 
of the Devonian Ptyctodontidas. "Three genera of Paleozoic Chinue- 
roids, known only by remains of this dentition, constitute the, at pres- 
ent, imperfectly definable family Ptyctodontidse. These are Ptyctodus. 
Rhynchodus and Pal?eomylus, distributed throughout the middle and 
upper Devonian of northern Europe and North America. The 'jaws,' 
or dental plates as they are more properly called, are rarely well pre- 
served, and invariably occur in the detached condition." 
While the bulk of a large amount of the new material came from 
the state quarries of Iowa, important collections were obtained near 
Milwaukee, Wisconsin. C. R. K. 
Geological Survey of New Jersey, Ati/iual Report of the State 
Geologist [Prof. John C. Smock] for the year i8gy. Pages xl and 
368, with 13 plates, and 25 figures in the text; Trenton, 1898. 
.The administrative report, 28 pages, concisely noting the year's 
work, is followed by reports of progress, on the surface geology, by 
Prof. Rollin D. Salisbury, in 22 pages, with a preliminary map of the 
surface formations of the state; on the Newark system or Red Sand- 
stone belt, by Dr. Henry B. Kiimmel, in 137 pages, with a map and 
eight other plates; on the Upper Cretaceous formations, by Prof. Wil- 
liam B. Clark, in 50 pages; on artesian wells, by Lewis Woolman, 85 
pages; on the drainage of the Hackensack and Newark tide-marshes, 
by C. C. Vermeule, 19 pages, with three plates; and supplemental notes 
on the mining industry, by George E. Jenkins, 41 pages. 
Professor Salisbury revises his former nomenclature of the surface 
deposits south of the glacial drift area. The Beacon Hill formation 
remains of undecided age, late Miocene, or subsequent. The name 
Bridgeton formation is proposed for the early part what was for- 
merly called the Pensauken, this name being still retained for the 
later part; the Bridgeton beds are regarded as the probable eciuiva- 
lent of the Lafayette; and the Pensauken beds, under their restricted 
definition, as correlative with the early Albertan or Kansan glaciation. 
Another new term, the Cape May formation, is proposed for the de- 
posits of Late Glacial and Early Postglacial age in the region south 
of the direct efifects of the ice-sheet and its drainage. This formation 
includes the later part of what Prof. Salisbury ha.<? before called the 
Jamesburg formation; and its earlier part, which is less distinctly de- 
veloped, is neglected in the present mapping.
