Annual report of the Commissioners of Inland Fisheries made to the General Assembly . tage Lobster Drawij from Life by Philip B, Hadley, 19 05. REPORT OF COMMISSIONERS OF INLAND FISHERIES. 233 EXPLANATION OF PLATE 33. Young male lobster; fourteenth stage; length, 65 mm.: age, approximately 14 months. First antenna: These are relatively longer than in the fourth stage; the olfactory setaeare not distinct. Second antenna: The endopodites have developed into long whip-like filaments longerthan the whole body; the exopodites show no further development. Eyes: These are relatively smaller. Chelipeds: These are differentiated, after the sixth stage, into a nipping and a crushing claw; the tip of the dactyl often closes far past the tip ofthe propodos. Ambulatory appendages: As in the fourth stage; the atrophied stumps of the exopodites disap-pear after the fifth stage. Abdominal appendages: Much as in the fourth stage; the external reproductive organs (modifiedswimmerets in the case of the male) have appeared during the seventhor eighth stage, on the first abdominal Plate XXXIIT, Young Male Lobster Drav^vT from Life FiY Philip B , REPORT OF COMMISSIONERS OF INLAND FISHERIES. 235 EXPLANATION OF PLATE 34. This specimen, whose age can not be accurately estimatec, but can not beless than sixteen or eighteen years, was taken from a fish trap in the southernpart of Narragansett Bay, where it had become entangled in the meshes. Themassive crushing claw was larger than the whole cephalo-thorax, and shows wellthe 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. Theeyes were small, scarcely larger than shoe buttons. The appendages were allintact, but much worn and stubby. The exoskeleton was extremely thick andheavy, deeply scarred, and beset with barnacles and moUuscs, several of whichhad grown into the articular membranes between the joints of the chelpeids.
