plates liad fully developed, and a sort of papule had formed 

 above them, and the mite had taken upon it the appearance of 

 Arrheuiirns caudatas, fig-. 4 ; the <^eneral colour of the mite 

 however continued to be pale, and rather transparent, the side 

 coeca brown. After this I sent the living mite to Mr. Soar for 

 his examination. He wrote to me October 14th. He thinks it is 

 Arrhcniinis caudahis, and the absence of the usual colouring of 

 that mite is perhaps due to its being de\eloped in confinement. 

 On October i6th I found it dead, and so mounted it. It 

 certainly was very diflFerently coloured to any A. caudafns 1 

 have before seen, and I still think it a variety of that mite, and 

 suggest it being called ' Arrheniinis caudafns majitotioisis,' 

 until further investigation shows that the ordinary A. catidatus 

 goes through all these diflferent changes during its final growth.
