248 SUPPLEMENT TO 



either does actually live, or has done so formerly, along 

 the whole intervening line. I will now enumerate the 

 species alluded to in the preceding pages and indicate 

 briefly the habitats which they are known with cer- 

 tainty to occupy. 



I. Aiypus piceus, Sulzer (ex Simon). The builder 

 of the tubular nest the silk lining of which is 

 figured at A in PI. XIII. It is stated by M. 

 Simon* to be common in all the centre, east, and 

 west of France, but it remains doubtful whether this 

 exact form is found in England or not, the true 

 characters and habits of the English species being 

 still uncertain. 



II. Cyrtanclienius elongafus, Simon, constructing the 

 funnel type of nest. It inhabits the neighbourhood 

 of Fez in Morocco. 



III. Cteniza Mofjgriclgii^ Cambridge (formerly de- 

 scribed under the name of Ct. fodiens\), one of the 

 many builders of a nest of the cork type ; I have 

 hitherto found this spider only at Mentone and San 

 Remo. It will probably be discovered in shady 

 valleys in the neighbourhood of Nice. 



IV. Ct. fodlens, Camb. {Ct. Sauvagii, Eossi ex 

 Simon) : large nest of cork type ; inhabits Corsica. It 

 has been said that the species found near Pisa [Ct. 

 Sanvagii) is the same as that which is so common in 

 Corsica, but it is desirable to have further confirmation 

 of this. 



V. Ct. Calif ornica, Camb. — Large nest of cork type. 

 Found near Visalia, about 350 miles south of San 

 Francisco, by Mr. G. Tread well.
