ing. of the University of Deseret, a cast of a slab containing some 
undescribed footprints. The slal) was first used as a door-step 
by a citizen of Salt Lake City. While serving •• such base uses "' 
it was discovered by Dr. John R. Park, president of the Univer- 
sitj' of Deseret and secured for the University museum. The 
casts were made by Prof. Ward, of Rochester. The tracks are 
three inches long and about three inches wide. There is in each 
the impression of three stout, clumsy toes, behind which is the 
imprint of a thick, well developed pad. The impressions of the 
fore and hind feet do not coincide, nor do they overlap to an}' 
appreciable extent. The stride of the animal was about eighteen 
inches. 
So far as learned from Prof. Whiting no description of the 
tracks has been published. The relations of the animal, and the 
geological horizon from which the slab was obtained have not 
been determined. 
In the Anxals and Magazine of Natural History for July, 
1891, Dr. P. Herbert Carpenter has a somewhat caustic review of S. 
A. Millers Description of some Lou tr (\irhoniferous Cfinoids from 
Missouri, published b}' the Geological Survey of Missouri, 
and Miller and (jrurleys Description of some new Genera and 
species of Ecli inodermata from the Coal Measures and Snhcarhon- 
iferoiis Rocks of Indiana. Missouri, and Iowa, published at Dan- 
ville, 111. The papers referred to contain descriptions of six 
new genera and over ninety new species of Crinoids. In sum- 
ming up his review Dr. Carpenter expresses himself thus severely : 
' • Three at least, and probabh' four, of his [S. A. Miller's] last 
six new genera of Crinoids would never have been proposed had 
he taken the trouble to make himself properly acquainted with 
the bibliography of his subject; and I suspect that quite half of 
his ninet}- new species Avill prove to lie synonyms when they c<jme 
to be revised. 
Careless and ill-informed authors of this class are the terror of 
sj'Stematists in all V)ranches of biology. Their sole object seems 
to be the association of their names with as many • new species " 
as possible, and ones first impulse on seeing ' A Description of 
Some New Genera and Species, " etc. , is to parody • The Bogie 
Man,' and say with bated breath, 
'Hush! Hush! Hush! Here comes the species man.' "
