214 SUPPLEMENT TO 



that of the Eiviera and of the wliole Mediterranean 

 region, leads me to hope that their range may in 

 reality be much more widely extended than has 

 hitherto been supposed to be the case. 



A glance at the vegetation of this district will 

 suffice to show how little there is that betokens either 

 a warm or dry winter climate ; for here the myrtles, 

 oranges and olives are left far behind, and in their 

 place we see tall hedgerow elms, and poplars bearing 

 mistletoe on their branches. 



Here therefore we are met by the question. How do 

 these Bordeaux spiders contrive to live under condi- 

 tions so different from those to which their relations 

 on the Eiviera have adapted themselves ? How do 

 they bear the cold and damp of the long winter, and 

 how is it that one frail upper door suffices to protect 

 their nest from molestation ? 



The thick coating of dead leaves, which covered 

 the banks even when we found them, no doubt aids 

 largely in their concealment, and the colder climate 

 probably diminishes the number of their enemies, but 

 their means of subsistence are most likely also less abun- 

 dant and their period of active life shorter. 



The next type we have to consider is a totally new 

 one, and may be distinguished as the single-door 

 branched loafer nest. I detected this nest at Montpellier 

 but a few days before the visit to Bordeaux alluded to 

 above. 



Circumstances unfortunately prevented me from 

 following up my discovery as closely as I could have 

 wished, and it appears moreover that this nest is far 

 less common at Montpellier than the typical cork 

 nest [Nemesia ccementaria).
