I believe that the specimens recorded from farther south than Mon- terey Bay are a distinct species from R. siibquadratus. Those seen and described by Dr. Holmes from San Pedro as Fabia subquadrata are the species which follows, R, lowei. RAPHONOTUS LOWEI Rathbun. Fabia subquadrata Holmes, Occas. Papers Calif. Acad. Sci., vii, 87, 1900 (part). Raphonotus lowei Rathbun, Amer. Nat., xxxiv, 590, 1900. General appearance like that of R. subquadratus; differs as follows: In R. lowei the turned-down front has no trace of a transverse groove and is naked; in R. subquadratus the turned-down front has a shallow transverse sulcus which is covered with pubescence. In R. lowei the last joint of the maxilliped does not reach the end of the penultimate joint, as it does in R. subqtiadratus. In R. lowei the palm of the chela does not widen dis- tally; its margins are subparallel or a little convex; its lower surface has only one line of hair, which is con- tinued to the end of the poUex; in R. subquadratus the Fig. 93.

In R. loiuei the fingers are less arched and less gaping than in R. sub- quadratus. The carapace is also a little wider in our species. Dimensions.—Female, length of carapace lo mm.
