96 ANNALS OF SCOTTISH NATURAL HISTORY 



pedipalps to alter the position of the mass, and, having done 

 so, it retained a hold with its left pedipalp for four minutes. 

 At 9.2 another Chelifer latreillii that had up to this time 

 been quietly resting about an inch from the scene began to 

 move about and presently came round to where the first 

 was feeding. The feeding Chelifer seemed to know of the 

 other's approach before as yet this latter was within touching 

 distance, and stretched forth its pedipalps beyond the mass 

 on each side, guarding it and defying the second Chelifer 

 in such a threatening manner that the latter took the hint 

 and moved off. The first Chelifer once more removed the 

 mass with its pedipalps, and brought another portion of it 

 into contact with its chelicerse, then again withdrew its 

 pedipalps. At 9.10 it repeated this performance, and began 

 to move off backwards, carrying the mass in its chelicera; 

 alone. At this hour daylight was beginning to fail me, 

 and I touched the Chelifer to drive it from the edge of the 

 box that I might close it up ; it moved off carrying the 

 mass in its chelicerae, without using its pedipalps at all, 

 and settled again. 



Mr. Wallis Kew, who has watched this feeding process 

 to a conclusion, says that " after the meal Chelifer latreillii 

 may be seen to bring one of the great pincers towards the 

 mouth in the most deliberate manner for the purpose of 

 removing the remains of the prey." 



One species of False-scorpion, the blind Chernes nodosus, 

 lays hold of flies and of other forms of prey many 

 times too large for it, and, instead of being able to bring 

 the fly to closer quarters with its mouth, it is itself carried 

 off by the fly whithersoever the latter pleases, and is often 

 found hanging by a pedipalp to a fly's leg. Yet in the end 

 it seems probable that Chernes nodosus, by patiently waiting, 

 may get his opportunity of feeding on his carrier when the 

 fly dies. The whole question of relationship between 

 False-scorpions such as Chernes nodosus and their carriers 

 has been fully discussed by Mr. Wallis Kew in the 

 "Naturalist" for July 1901, pp. 195-215, who writes in his 

 summary : " The subject will bear further investigation ; 

 but from the facts now in our possession it seems impossible 

 to avoid the conclusion that pseudo-scorpions found on the
