Tebennophorus dorsalis Binney. 
This slug is common in Indiana. However, only a single specimen was 
taken in the pond, Oct. 16, 1910, in the debris at the bottom. (It seems to 
have been recently introduced. ) 
Anecyclus tardus Say. 
Not uncommon. ‘This shell is reported by Call ((99) to be common in 
the Wabash, Ohio and Maumee rivers. In all references that I have been 
able to find, it is recorded from streams. But most expeditions that were 
for the spcial purpose of collecting molluscs, were made along streams. 
The forms from the land-locked pcols have been collected more incidentally. 
These facts, together with the small size of the species, account for the oft 
repeated statement of its distribution. 
Vertebrata— 
AMPHIRIA. 
Amblystoma jeffersonianum Green. 
The adult of this ferm has not been taken in the pond, but is known 
from the ravine to the north. Egg masses, referred to this species, were 
present March 17, 1910. One mass contained 19 eggs and another 2%). 
March 24, 1911, a mass was observed containing 24 unhatched larvee. Di- 
ameter of outer envelope, 18 mm. Diameter of total mass, 60 mm. Length 
of larvee, 13 mm. Fastened to grass 13 cm. below surface. 
Diemyctylus viridescens Rafinesque. 
Common. Six taken in an area about one foot square in February, 
1911. Its habits have been worked out in detail by Gage (91) and Jor- 
dan (’93). 
HWyla pickeringii Holbrook. 
Three. Numerous. Appeared March 24, 1910. Eggs in May. 
Rana catesbiana Shaw. 
Common. Nine specimens taken during May, 1910. Egg-laying period, 
June and July. Recently laid eggs as late as July 15. Reduction in level 
kills many eggs. 
AVES. 
Anas discors Linnzeus. 
A duck was flushed from the pond April 21, 1909. Identification was 
made while the bird was on the wing. It circled three times, coming quite 
near. The identification is probably correct. This bird has the greatest
