 composed of minute spherical ova or capsules, attached by short pedicles

 --instituted a cluster. The gradual increment of the whole is so great as 

 to augment the mass, which protrudes from below the edges of the apron, 

 and raises it above the rest of the shell. 



Myriads of ova were dropping from the mass on the eighth and 

 ninth of January, as the Cam, r niu-na.i does not deposit its spawn, like 

 many animals, on extraneous substances. While still adhering in its 

 place, the skin of the capsule grows thinner and thinner, it partial!

 figs. 8, 9, 10, 11. 



Many of the young were hatched on the 12th of January ; their 

 farther multiplication followed for some time. At this early stage they 

 are extremely minute, nor bearing the slightest resemblance to the form 

 of the parent, neither, unless having watched their progress incessantly, 

 could I have credited their origin. All are of light grey colour ; the 

 body rather globular, with a llattened tail, somewhat resembling that of 

 a lobster, consisting of six or seven evident articulations, and a forked 

 extremity. The feet are indistinctly discernible. A long spine, wanting 

 in some, rises from the back of others. 



Unfortunately these young animals are too delicate to remain the sub- 

 ject of permanent observation. Similar facts to those above specified have 

 been repeatedly witnessed on other occasions ; but I have been always 

 disappointed in the occurrence of those metamorphoses which would 

 have shewn their advances to perfection. 



:i remarks, however, are not to discourage other naturalists, 

 who will ever find the Cancer mcenax a convenient and suitable subject 

 for elucidating the properties of its genus.
