pi. xix, fig. 11^) ; the obtuse ^ terminal joint is almost once-and-a- 

 half as long as the penultimate, and the posterior margin of the 

 latter is two-and-a-half times as broad as this joint is long. In 

 the younger female the terminal segment is for one-third of its 

 length impacted in the penultimate, in the other female not even 

 as far. 



Chelipedes equal, both in the male and in the female. Outer 

 surface of the arm transversely wrinkled, neither the upper nor 

 the inner border of the arm ends in a tooth or spine ; but the 

 inner border presents a slight, subterminal dilatation and appears 

 finely, though irregularly, denticulate along its whole length ; about 

 thirty very small acute teeth, recognisable through a lens, occur 

 on the lower border. Upper surface of the wrist covered, especially 

 on its outer side, with finely crenulate ridges, inner angle obtuse — 

 not dentiform ; examined by means of a lens a few minute setse 

 are observed on the upper surface. In the male the horizontal 

 length of the chelae (fig. 6) measures three-fourths the distance 

 between the outer orbital angles ; the fingers are a little longer 

 than the palm which is one-fourth higher than long. To the naked 

 eye both palm and fingers appear smooth. Examined by means 

 of a magnify ing-glass the rounded upper border of the palm, 

 which carries no pectinated crests, appears a little granular by very 

 small granules ; but for a few oblique striations near the carpal arti- 

 culation, the convex outer surface of the palm appears perfectly 

 smooth ; the rounded lower margin is'slightly granular, the granules 

 being microscopical, though slightly larger and rather acute on the 

 inner side and extending here to the middle of the immobile 

 finger. The fingers are pointed ; their convex, outer surface is 

 smooth, though somewhat punctate ; the tapering dactylus has 

 neither ridges nor grooves, but is covered above with minute subacute 

 granules that extend to near the tip and are rather irregularly 

 arranged. The inner surface of the palm presents no trace of 

 a transverse crest or ridge, but it carries a few, very small, sub- 

 acute granules, visible by a lens, one or two of which near the 

 upper border are a little larger than the rest. The immobile 

 finger has two small, conical teeth, one contiguous to the hornj^ tip, 

 the other near the base, and between them are six or seven smaller 

 teeth, while two or three occur near the base ; the toothing of the 

 dactylus is nearly the same. 



The chelae of the female are comparatively smaller, measuring 

 three-fifths only of the distance between the outer orbital angles ; 

 but the fingers are comparatively longer than in the male. The 

 oblique striae near the carpal articulation are hardly developed and 

 the upper border of the dactylus is nearly smooth ; the granules on 

 the inner surface of the palm are also fewer in number and smaller. 



The ambulatory legs apparently closely resemble those of 

 S. sylvicola. The meropodites, which have a subterminal, acute 

 tooth on the anterior border, are slender like the other joints, and 

 their outer surface is covered with short, transverse, crenulate Hues, 

 — that of the last pair excepted, these being nearly smooth ; so.
