Tebennophoriis 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.) 

 Ancyclus 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 pools 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 — 



AMPHIP.IA. 



Amblystoma jeffersonianum Green. 



The adult of this form 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 ^n. 

 March 24, 1911. a mass was observed containing 24 unhatched larvfe. Di- 

 ameter of outer envelope. l.S mm. Diameter of total mass, 60 mm. Length 

 of larvffi, 1.3 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). 

 Hyla pickeringii Holbrook. 



Three. Numerous. Appeared March 24. 1010. Eggs in May. 

 Kana catesbiana Shaw. 



Common. Nine specimens tak-en during May, 1910. Egg-laying period. 

 June and .July. Ifecently laid eggs as late as July 15. Reduction in level 

 kills many eggs. 



AVES. 



Anas discors Linnreus. 



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
