A FAMILY OF YOUNG TRAP-DOOR SPIDERS. "^^ 

 (Pachylomerus, 4 — spinosus.) 



Two questions were asked by Mr. Moggridge about the 

 habits of young trap-door spiders. For the answer to these 

 he was unable to inake any observations, so far as the record 

 shows. The questions are ; 1st, do young traprdoor spiders 

 make nests like those of the parent without being shown ?
