The annals and magazine of natural history : zoology, botany, and geology . .Cymodocea caudata, Ives, Proc. Acad. Nat. Sci. Philad. 1891, p. 188, pi. vi. 11-14. Pacific Coast of North America. 187 Fis?. of three coalesced segments. There are three transverse ele-vations on tliis segment, whicliare densely covered with gra-nules. The terminal segmentbears three transverse eleva-tions at the base, the medianone terminating in a its posterior margin is aquadrangular excavation, witha long median tooth, bearing aspine at its extremity. At thebase ot the tooth is a smallelevation. On either side ofthe terminal excavation, a shortdistance up the lateral margin,is a small spine. The fixed inner branch of the uropoda issmall and short; the outer branch is long, blunt at theextremity, somewhat incurved, and reaches, when open, muchbeyond the terminal segment. The margins of the terminalsegment and the edges of the outer branch of the uropodaare pubescent. The legs are all simple, ambulatory. One specimen from Cerros Island, Lower California, wascollected by Mr. A. W. Anthony, at a depth of 20 fathoms. Type. No. 22649, N. M. CillccBa granulosa, x 8. Lastthoracic segment and abdom
