I 56 FLORIDA GEOLOGICAL SURVEY-EIGHTH ANNUAL REPORT. 
wolves. The breadth across the zygomatic arches is contained, in 
the length of the skull from the premaxillaries to the occipital con¬ 
dyles of the California wolf, about 1.6 times; of the Florida wolf 
about 1.7 times. The differences are more pronounced when meas¬ 
urements across the nose or jaws are compared. The width meas¬ 
ured between the outer sides of the superior sectorials is contained 
in the length of the skull of the California wolf 2.6 times; of the 
Florida wolf 3.0 times. Of the two skulls, measurements of which 
are recorded in columns 2 and 5 of the table, that from Florida, 
although the longer of the two, is actually narrower throughout, 
and noticeably so across the nose, the increased length of the skull 
being found entirely in front of the posterior nares. 
It is thus shown that of the Canis dints group of wolves at least 
two species are represented, that of the Atlantic Coast being dis¬ 
tinct from that of the Pacific Coast. 
The species, Canis dims, was established by Leidy upon a sin¬ 
gle bone, a left maxillary, and hence it is by no means easy to de¬ 
termine its limitations. With regard to the probable relationship 
of the Florida wolf it may be noted that between the type locality 
of C. dims at Evansville, Indiana, and Florida no effective barrier 
intervenes. The fossils listed by Leidy as being in asssociation 
with C. dims are Megalonyx jeffersonii, Tapirus liaysii, Equus 
americanus, (E. complicatus), Bison amencanns and Cervus vir- 
ginianns. If more complete material of Canis dims is subsequent¬ 
ly obtained from the type locality, it is possible that the hlorida 
wolf may be found to be identical with that species. However, 
since this cannot be determined from the fragmentary type of 
Canis dims, and since that specific name is now associated with the 
wolf of California it seems preferable to describe the hlorida wolf 
under a distinct name. 
Although not found in immediate association with the human 
remains this wolf is from the stratum which contains human bones, 
and it is a pleasure to be able to name this fine new species in hon¬ 
or of Mr. Frank Ayres by whom the fossil human remains at Vero 
were first found. The species may, therefore, be known as Cams 
ayersi. The specific characters are as follows: 
Size large, exceeding that of the Mexican timber wolf, Cams 
mexicanus, or the gray wolf, Canis occidentalis and equalling that 
of the extinct Canis 'dims. Snout slender, premolar teeth spaced, 
not being crowded in the jaw. Carnassials large, Pm' with but
