Remarks on an unusually large Marine Lobster caught off 

 Newport, Rhode Island. 



I am indebted to Mr, Charles E. Ash, of Newport, for the opportunity 

 of examining a lobster of unusually large size, taken off the island of 

 Rhode Island, June 10, 1900, by a fisherman who was trawling' for cod, 

 using a line to which many hooks were attached. Lobster-pots are too 

 small for the capture of very large lobsters. This one weighed 27 

 pounds, and ranks with the largest examples of its species. The crush- 

 ing claw is on the left side. This lobster is normal and perfect in all 

 its parts. 



In the Bulletin of the American Museum of Natviral History, 

 N. Y., (Vol XII, pages 191-194, plate IX, published December 30, 

 1899), Professor R. P. Whitfield published a description and measure- 

 ments of two phenomenally large lobsters, captured off Atlantic High- 

 lands, New Jersey, during the spring of 1897. For convenience of com- 

 parison, I have followed the measurements of these two specimens, as 

 taken by Doctor E. O. Hovey of the American Museum, presenting 

 those of the present specimen in the third column (No. 3), Nos. 1 and 2 

 being those from New Jersey.
