not bring out the detail, hence I made the model in clay. It should 
have accompanied the text of “ The Recidivist," American Naturalist, 
June, 1894, but an injury to my right hand prevented a completion 
of the model in time.

The Habits of Amblystoma opacum.—I once secured a num- 
ber of marbled salamanders (Amblystoma opacum), and kept themin a 
small enclosure where they lived under chunks of wood. They did 
not curl up as they are said to do, but lay stretched out, showing but 
little sign of life. Their food was larve and earthworms; I believe 
they will not eat flies nor ants. They are so soft, weak and helpless, 
that I thought that they could not dig deeper than merely sufficiently 
to hide themselves, but, out of deference to the opinion of Mr. Nicho- 
las Pike, who says that they will burrow to a depth of three feet, I 
sunk a board two feet deep around their enclosure. I was absent for 
a time, and returned to find my salamanders missing. On digging 
carefully, I found unmistakable signs of their burrows extending 
beneath the sunk board. They had burrowed out and escaped, cor- 
roborating two feet of Mr. Pike’s story —ANnous GAINES. 
Habits of Ophibolus getulus.—Early in July I captured an 
Ophibolus getulus, a small but very fine specimen, answering perfectly 
to the description of the type given by Dr. O. P. Hay, in the Seven- 
teenth Annual Report of the Indiana Geologist.
