of it. I was not successful in my endeavors to get them to eat while 
in confinement. They appear to endure imprisonment well. 
During the summer of the present year my son, W. P. Hay, secured 
two additional specimens of this cave salamander in the region about 
Bloomington. One of these was taken in May’s Cave, about five miles 
south of Bloomington and a mile west of Clear Creek Station. It was 
found sticking to the wall of the cave, about four feet above the water 
and about one hundred yards from the cave’s mouth. The other was 
captured in Kern’s Cave, one mile southwest of Bedford, in Lawrence 
county. This locality is twenty miles south of May’s Cave, and both 
are about a hundred miles west of Brookville, the original place of the 
discovery of the species. This shows that the animal is pretty well 
distributed throughout the southern portion of Indiana, and will prob- 
ably occur also in the caverns of Kentucky. The specimen taken in 
Kern’s Cave was also found clinging to the wall above the water, and 
at a distance of about a quarter of a mile from the entrance. Neither 
of the specimens made any effort to escape capture. Attention was 
attracted to both by the gleaming of their eyes in the candle-light.

Color Patterns in Cnemidophorus.—At the last meeting of 
the American Association for the Advancement of Science I read a 
paper on the color variations in two species of the above-named 
genus of lizards, the C. gularis B. & G. and C. tessellatus Say. In the 
young of both species the color consists of longitudinal stripes, six in 
the former and four in the latter, which has a lateral series of spots in 
place of the external stripes. This coloration is permanent in some 
of the C. gularis and in the C. £. gracilis. In both species can 
be traced an identical series of color varieties, which have especial 
geographical ranges, and which have mostly received names as species. 
The first modification is seen in the appearance of pale spots in the 
interval between the stripes, a character which partly defines the 
C. gularis B.& G. These spots are greatly enlarged in the C. gularis 
scalaris Cope, joining the stripes and breaking up the ground color 
into spots. On the other hand, the stripes may also be broken up 
into spots, producing a light-spotted form, the C. g. communis Cope. 
Returning to C. g scalaris, the dark spots may be confluent transversely. 
forming a transversely banded form. ‘This transverse banding com- 
mences at the posterior extremity of the body. When it is restricted 
to this region and the anterior color pattern disappears, we have the
