Gills 3 and 4 in males and 3 in females elliptical, long axis usually parallel to body; gill 4 in females oval or elliptical. Propodus of pereopods 5-7 without distinct grasping spines, palmar margin usually with numerous stout setae; grasping margin of dactylus serrate. Abdomen of male typical of genus except for hooked papillae at tip of appendage, female with small palplike appendage. Variation.—The shape of the gills is variable. In males the long axis is usually parallel to the body; however, either or both may occa- sionally be at various angles to the body. In the females either or both of the gills may have the long axis parallel to the body or may be at any angle. In small males the poison tooth on the propodus of gnath- opod 2 may be more proximal than midlength; however, the dactylus remains quite short. The palm of the propodus of pereopods 5-7 varies in setation from numerous stout setae to very Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original United States National Museum; Smithsonian Institution; United States.
