LECANOPSIS BBEVIOOBNIS. 17 



Two of the specimens obtained had secreted their 

 ovisacs ; the other two were naked, and being smaller 

 were evidently young adults; but although living 

 they showed no signs of life, and were perfectly 

 inert, which is most remarkable, seeing that they were 

 not attached to any substance whatever, and I can 

 only surmise that they had completed their final change, 

 and were on the point of making their ovisacs prior to 

 parturition. 



The only cabinet specimen in my possession which 

 has not been subjected to boiling potash is of an 

 orange-brown colour ; it is highly convex above, but 

 has shrunk beneath, and is not at all unlike a dried 

 miniature Chiton, having also retained its segmentation, 

 and the extremities are curved downwards.
