By C. H. EoBsoN. 

 {Read before the Wellington Philosophical Society, 24t7i February, 1877.] 

 My attention was first directed to our numerous spiders by an interesting 

 account of the trap-door spider by Mr. E. Gillies.* After having read the 

 paper above quoted, I began to collect specimens of such spiders as were to 

 be found about Cape Campbell, more with the Iwpe of finding some of the

Soon after this one of my boys told me that, while playing on the cape 

 at low water, he had seen a spider in one of the tidal pools. Never having 

 heard of the existence of a sea-spider, I thought he must have made a 

 mistake ; and I was more disposed to think so when I began to consider 

 that, even if a spider could live in the sea, he could not do so without food, 

 and he would not find any flies or beetles there. I may here remark, that 

 up to the present time I have not been able to discover what these spiders

On going to see what it was, I found a veritable spider quite at home

 the rocks about here are full. All the spiders of this kind which we have
