2 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. 
For the best Weigert preparations, Herrick’s method of fixation 
for fishes with Flemming’s fluid was found the best for the lizard also, 
although I was unsuccessful in my attempts to get the best results in 
both the central and peripheral fibers by a single treatment. That — 
is to say, when the sections were decolorized properly for the central 
nervous fibers, the peripheral nerves were decolorized too far. On the 
whole I found it much more satisfactory to base the study of the 
peripheral nerves on the Vom Rath series, and the present paper 
chiefly rests on the findings in such material. 
D. SYSTEMATIC POSITION OF ANOLIS. 
Following Cope (:00, p. 158, ff.), we have the following division of 
the living Reptilia: — 
Class MonoconDyYLtIa. 
Subclass Reptilia 
Orders Testudinata 
Loricata 
Rhynchocephalia 
Squamata 
Suborders Ophidia 
Sauria 
The group characters of the Sauria are as follows: “Quadrate bone 
articulating with the exoccipital; parietal bones not closing the brain 
case in front; generally an epipterygoid and sternum; teeth with 
dentinal roots; phalanges with condyles” (p. 178). The family 
Iguanidae is represented in North America by twelve genera; it is 
subdivided as follows: — 
Subfamilies Anolinae 
Basiliscinae 
Iguaninae 
The genus Anolis falls under the first of these three subfamilies, 
which includes six known genera, Anolis being the only one found in 
the United States. Cope (p. 233) describes Anolis carolinensis and 
states that it “is distributed from the Rio Grande to Florida, inclusive, 
and as far north as Kinston, North Carolina. It is, moreover, com- 
mon in the Bahama Islands and Cuba, where it reaches a size rather 
superior to what is usual in the United States.”” Among other Iguan- 
idae found in the United States*are the well-known forms Sceloporus
