Excerpt from Bulletin of the Museum of Comparative Zooelogy at Harvard College, in Cambridge, 1882-1883, Vol. 10 The chelipeds are a little longer than the carapax including the rostral horns, and scarcely stouter than the ambulatory legs; the chela is nearly as long as and no stouter than the merus, the basal portion subcylindrical, nearly naked and smooth except for minute, scattered papillae, like those on the surface generally except that they are smaller and much more scattered the digits are a little more than half as long as the basal portion, a little curved, slightly com pressed, smooth, and with the prehensile edges' regularly dentate. The ambula tory legs are all armed with a dentiform spine at the distal end of the merus the first pair are nearly twice as long as the chelipeds, and the succeeding pairs are successively a little shorter. The second and third segments of the abdomen of the male are expanded, and the first and second are each armed with a small median tubercle.
