 found in two interesting papers * by Mr. and Mrs. Peckham, 

 which are well worth a careful reading. One, out of many in- 

 stances described by these two observers, will be sufficient for 

 the present purpose. 



The male of a species of Habrocestum differs from the female, 

 in having his first legs of a delicate green colour fringed with 

 white hairs ; these ornamental appendages are displayed to 

 every advantage while the male is paying his addresses to the

 to be "interested 'in his display"; with reference to the 

 mating habits of another spider, the female is said " to become 

 excited, and watch the male with absorbing interest." The 

 late M. Alphonse Karr, in his delightful essays entitled " A 

 Tour round my Garden," gives a humorous description of the 

 courtship in spiders. " My friend," he says, " was more 

 fortunate, for the belle advanced towards him, whilst he waited 

 for her in visible anxiety ; but whether he perceived in her 

 behaviour any unsatisfactory sign, or whether the coquette had
