prolegs, are invariably eaten.” 
At the same meeting Mr. A. G. Butler, of the 
British Museum, communicated the results of his 
observations with lizards, frogs, and spiders, which 
strikingly corroborate those of Mr. Weir. Three green 
lizards (Lacerta viridis) which he kept for several 
years, were very voracious, eating all kinds of food, 
from a lemon cheesecake to a spider, and devouring 
flies, caterpillars, and humble bees; yet there were

(Anthrocera filipendule). These would be first seized 
but invariably dropped in disgust, and afterwards left 
unmolested. Subsequently frogs were kept and fed 
with caterpillars from the garden, but two of these— 
that of the before-mentioned Magpie moth, and that

With spiders the same thing occurred. These two
