see what they would do when insects were put into the box. 

 Spiders kept in captivity must be suppUed with water daily 

 or they will soon die. If they are "watered" with a medicine 

 dropper they soon learn to come and drink from the end of 

 the dropper. By gently pressing on the bulb of the dropper 

 the spider can be supplied with water with but little trouble 

 and the proceeding is really interesting. 



CLASSIFICATION. 



In classifying the species of spiders studied, Bank's Cat- 

 alogue of Nearctic Spiders was followed. Following each 

 species is the name of the man who identified it. A later cat- 

 alogue on the synonomy of spiders is Petrunkevitch's which 

 may be found in Volume XXIX, Bulletin of the American 

 Museum of Natural History. The classification by families is 

 as follows: 



Lycosidae: Lycos a avida Walckenaer. 



Lycosa carolinensis Walckenaer. 

 Lycosa fatifera Hentz. 



Attidas: Phidippus audax Hentz. 



Phidippus podagrosus Hentz. 

 Clubionidffi: Castianeira descripta Hentz. 

 Thomisidae: Misumena vatia Clerck. 

 Pisauridse: Dolomedes tenebrosus Hentz. 

 Dictynidce: Dictyna frondea Emerton. 



Agelenidas: Agelena naevia Walckenaer. 

 Coras medicinalis Hentz. 



Epeiridce: Metepeira labyrinthea Hentz. 

 Leucauge veniista Walckenaer. 

 Epeira trivltatta Keyserling. 

 Epeira domicilioriim Hentz. 

 Epeira foliata Koch. 

 Epeira trifolium Hentz. 

 Epeira gigas Leach. 

 Argiope trifasciata Forskal. 

 Argiope riparia Hentz.
