of each, accompanying my short paper, will be found. The associa- 

 tion of the two, even then (1864-5), often attracted my attention. 



Dr. Gray has since told me the further adventures of these three 

 captives. They were all put into a cell together, and for a time all 

 went well, but within the last few days the Tiresias larva has cast 

 his skin and come out quite smart, whilst one of the pencil-tails 

 has died. Not only died, however, for every vestige of him has 

 disappeared. I need hardly say that strong suspicion of foul play 

 rests on the character of that Tiresias larva in this matter. 



The compendium of Generic Distinctions at the end of " Wood's 

 Natural History" (Vol. iii.) contains much information respecting 

 the Myriapoda, put in a convenient form for study. 



There is also some information, very good, but at the same time 

 very scanty, to be obtained in the " Micrographia Dictionary," 

 under the head " Myriapoda." 



I think I have now put before you as briefly as I could the most 

 valuable of the information I have been able to obtain, and it only 

 remains to me, after thanking Dr. Gray and Mr. T. C. White for 

 many hints, and Mr. Ward and Mr. Blatch for specimens which 

 they have kindly furnished me with, to indicate the method of 

 capture and keeping of the pencil-tails which has been found most 

 successful. Having discovered the objects of our search in the 

 localities I have pointed out, or in other new ones, a camel's hair 

 pencil and a test tube are indispensable to effect the removal of the 

 pencil-tails from their homes uninjured. 



Then, or as soon afterwards as possible, our tubes must be emptied 

 into cork cells such as I have described on a former occasion. It 

 will be well to introduce as food a small fragment of the bark also, 

 and if it is kept damp they will often be seen feeding upon it. So, 

 too, will they feed upon the blotting paper of the cell, and on one 

 occasion a healthy colony I had succeeded in capturing burrowed 

 their way through it and escaped, to die, I fear.

 wider-side of the insect, the hairs and scales, and a cluster of eggs.
