24 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. 
in the part of Bronn’s Thier-Reich devoted to the Reptilia, based his 
description of the cranial nerves of lizards largely upon the work 
Fischer published forty years previously. More recently Osawa (’98) 
has given a quite full account of the anatomy of Hatteria, in which 
the cranial nerves are described. This work fails of much of its use- 
fulness because of lack of plates; the text figures are too obscure to 
be of much use. Watkinson (:06) describes Varanus bivittatus, includ- 
ing the skull and musculature among her drawings. In matters of 
close comparison, however, her work has proved to be inadequately 
illustrated properly to supplement her description. In the same 
manner Cords (:04) attempts to meet a long felt need in the anat- 
omy of the nervous system of birds; but here, again, the lack of a 
diagram of the complete system, for the purpose of comparison, is felt. 
In addition to the works mentioned, the cranial nervous system of 
reptiles and birds has been touched upon by various authors in the 
comparative treatment of certain nerves or groups of nerves. 
In the following work on Anolis there is presented for the first time 
a description of the cranial nerves of an adult amniote form based 
upon a complete series of sections. 
F. SKELETAL STRUCTURES: 
1h: Seow 
The skeletal parts involved in this account are those which are 
related topographically to the cranial nerve roots or sérve for the 
attachment of muscles whose description follows, or have some other 
important, though indirect, relation to the main subject. Many 
points of secondary importance in regard to length of rami, points of 
branching, and course of peripheral nerves are explained when refer- 
ence is made to the skull and its foramina. The skeletal parts appear- 
ing in the transverse sections are not readily understood without 
reference to the entire structure, therefore the three drawings of the 
skull are made with accuracy with a view to their permanent value 
in any problem involving the comparative anatomy of the reptilian 
head. Cope (:00) is followed in naming the parts of the skull and 
hyoid apparatus. As he separates the Reptilia altogether on osteo- 
logical characters, the basis for a large part of his definition of the 
Sauria may be recognized in this skull, e. g., “Quadrate bone artieu- 
lating with exoccipital; parietal bones not closing the brain case ™m
