1897.] F. Finn — Experiments with a Tupaia and a Frog. 529 



Shortly after I could not find two of the non-warningly-coloured 

 butterflies I had put in its cage, as above mentioned. In the evening, 

 after having meanwhile given the Tupaia some meat and rice, the 

 former of which it had some time ago eaten, (the latter it seemed not to 

 like ) I found the D. genutia still uneaten in the cage. The last non- 

 warningly-coloured butterfly, a Catopsilia, I found outside the small cage 

 in which the Tupaia at present was kept. I put it in the netting, but 

 the animal would not take it. 



I then offered it a Danais limniace and another Catopsilia, fresh 

 specimens. These it smelt and would not eat. 



Next I put in a live Catopsilia, which the Tupaia eagerly pursued, 

 seized and ate. I then put in live specimens of D. genutia and limniace, 

 one each, neither of which it would take. Then I gave successively a 

 non-warningly-coloured butterfly much like those it had refused when 

 dead, in the morning, and five Catopsilias, all these being alive ; all 

 were eaten, and the animal smelt about for more, while the two Danais 

 recently given were still alive. It then readily ate a glossy green 

 Muscid fly. 



It then ate the Catopsilia which it had previously refused (see 

 above), while within two inches of the living D. limniace. 



Once or twice, in chasing butterflies, it grabbed at one or both 

 Danais, but did not bite them. 



July 16th. The two Danais put in the cage last night were still 

 alive and unhurt, though the wings of the D. genutia were torn and rub- 

 bed. I had noticed the animal smelling this more attentively last night, 

 and it was more inclined to seize it. The D. limniace was quite untouched. 

 The Tupaia ate a piece of plantain, and later a cockroach, readily. I then 

 took out these two butterflies, and offered them to Lizards (see Experi- 

 ments with a Lizard, under this date, J. A. S. B., 1896, Part II, p. 46.) 



I offered the animal to-day two plain-coloured caterpillars of a 

 species living in stick cases, which it ate, but rubbed them first 

 on the ground, and did not gobble them up immediately like the 

 winged insects. It seemed to have no idea of getting them out of the 

 cases for itself, though I saw it afterwards nibbling at one of these. 



In the evening, the animal being now in the aviary, where there was 

 plenty of meat, rice, and plantain, I put in with it a disabled Euploea, 

 which it smelt and refused ; then a disabled Junonia and another non- 

 warningly-coloured specimen ; these it ate readily. Then I gave it a 

 disabled Danais genutia, which was also examined and refused. Two 

 non-warningly-coloured specimens like the preceding were then eaten, 

 wings and all, as usual. I then took out the Euploea, and offered it to 

 a Lizard (see Experiments with a Lizard, he. cit.)
