drawings of the skull (Plate 1, figs. 1-3), and the cross-section 
drawings (Plates 4-7) furnish all the description called for in this 
connection. Certain cartilaginous elements appearing in the sections 
were not preserved in the preparation of the skull. 
2. Hyorp APPARATUS. 
The hyoid apparatus is entirely free from any cranial attachments. 
“The hyoid system in lizards consists of a glossohyal, which is con- 
tinuous with a basihyal tract, a hypohyal, often continuous with the 
basihyal tract, a ceratohyal, a first ceratobranchial, and a second 
ceratobranchial, which is always continuous with the basihyal tract. 
There may be in addition an epibranchial, which belongs to the first 
Taking Anolis carolinensis as 
typical of the genus in this respect, Cope (p. 232) says, “the hyoid 
apparatus has the extreme development seen in all the lizards with a 
gular compressed pouch or fan. That is, the ceratobranchials of the 
second pair are closely appressed and produced to a great length. 
First pair of ceratobranchials and ceratohyals simple, the latter at- 
tached to the extremities of the moderately developed hypohyals.” 
G. CUTANEOUS SENSE ORGANS. 
The cutaneous innervation and the epidermal sense organs deserve 
exhaustive study in the reptiles in view of the fact that these sense 
organs are apparently absent as such in mammals, although abundant 
in the Amphibia and fishes. On the other hand, mammals possess 
dermal tactile organs of problematic origin. Inasmuch as some new 
facts are presented in this general account of Anolis, a brief statement 
of what has already been described within the group of reptiles is 
necessary. Maurer (’95, p. 228) refers to Reinhardt’s (’61) article 
in which 191 species of snakes were examined for the epidermal sense 
organs. In 85 of these nothing of this nature was found; in 44 species 
_ there was one organ, and in 62 species two organs, to each scale. 
Maurer’s (’95, p. 17, 196-239) own work covers the field sufficiently 
for our purpose. This can best be understood by reference to his 
text figures (9-14), which include most of his illustrations relating 
to the distribution of these sense organs. Besides Hatteria, only one
