. Natural history of the American Decapoda (Crustacea); Lobster fisheries. Fig. 15 and 16.—Left and right future toothed and crusher claws of lobster in eighth stage, seen from above. The claws are of equal length, and the differentiation of the crusher is not apparent to the naked eye. Compare with figures 21 and 22. L, lock spine; p, compound proximal tubercle of crusher claw. Enlarged about 34 times. claws may appear to the naked eye essentially alike in form and size. Thus, to give a concrete example, a lobster in the eighth stage, measuring milimeters, September 22, showed a rather striking similarity in the forceps, the dimensions of which were as follows: Right claw (future cruslier): Millimeters. Length 7 Breadth i. 7 Left claw (future toothed forceps): Length 7 Breadth 4.
