The detailed measurements of this animal are given in table 30, No. 1, where they 

 may be compared with those of the small lobster, seen on plate 2, and with those of 

 the large specimens which I have recorded above. 



The large Boothbay lobster, which has already been referred to (p. 16), is 

 reported to have weighed as much as 40 pounds. I was told that it tipped a scale 

 which weighed up to 25 pounds, and would have weighed somewhat more. Its meas- 

 urement, however (table 30, No. 2), jiroves it to have weighed less than the Belfast 

 specimen, and a comparison of its length and the dimensions of its claws with the 

 large European lobster (No. 1 a, table 29) show that it could have exceeded this in 

 weight very slightly, if at all. Its true living weight was probably between 20 and 22 

 pounds. The shell of this lobster was cleaned by placing it in an ant-hill, and it is now 

 in a bad state of preservation. The claws are furrowed, pitted, and scarred, and the 

 carapace is scratched, as is apt to be the case with large old-shell lobsters. 



In the museum of the Peabody Academy of Science at Salem, Massachusetts, there 

 is a perfect specimen of a lobster (No. 3, table 30), said to have been taken at Salem
