to each other. From extreme restlessness the male became quite tran- 

 quil, and an actual embrace speedily followed. 



These creatures dwelt together amicably, and fed readily, and 

 this continued for some time. I wan in great hopes they would huv<* 

 lirv.il. whereby various obscurities regarding their progeny might have 

 been dispelled. 



But the male, unfortunately, died soon afterwards, just fourteen 

 months after having been acquired. 



I regretted this as an untoward incident, for several reasons. I 

 knew the animal's progress, its age could be nearly determined, and I 

 was familiar with its habits and treatment. But it is so with all living 

 creatures, only intervals of observation can be enjoyed. Many must 

 be studied to discover the properties of one. 



the periods of exuviation had been distinctly noted, proving.

The female above referred to, a fine but peculiar specimen, was taken 

 on July 22. A great proportion of white being intermixed with the

I hod not to wait long. 



Exuviation of this specimen followed" on the night of the first of 

 August. Except in size, the new shell exactly resembled the old ; the 

 markings in every respect were similar. The animal was now very 

 vigorous ; but it was ravenous in proportion. Though dwelling in per- 

 fect harmony with its companion, the male above mentioned, it would 

 deprive him of his provender by forcible assault, to be carried off and 

 devoured at leasure. 



Their union was unproductive. Its mode is in so for remarkable, 

 that the apron of each is folded bock on the cartilaginous hinge. 



This female, oiler rejecting food during three days, cast its shell 

 second time in the night of October 25, and came in so much larger
