REPORT OF COMMISSIONERS OF INLAND FISHERIES. 235 



EXPLANATION OF PLATE 34. 



This specimen, whose age can not be accurately estimatec , but can not be 

 less than sixteen or eighteen years, was taken from a fish trap in the southern 

 part of Narragansett Bay, where it had become entangled in the meshes. The 

 massive crushing claw was larger than the whole cephalo-thorax, and shows well 

 the development of the two great tubercles which, in the case of aged lobsters, 

 alone remain. The cephalo-thorax was broad, but the head portion narrow. The 

 eyes were small, scarcely larger than shoe buttons. The appendages were all 

 intact, but much worn and stubby. The exoskeleton was extremely thick and 

 heavy, deeply scarred, and beset with barnacles and moUuscs, several of which 

 had grown into the articular membranes between the joints of the chelpeids.
