192 DR. J. Gd. DE MAN ON THE PODOPHTHALMOUS 
pointed tips, therefore agree with those of S. Hdwardsi, but 
they are less strongly denticulated along their inner margins, 
presenting only some small teeth, of which the basal ones are a 
little larger than the others. The chelipedes of the female have 
quite the same form and structure as those of the male. 
The ambulatory legs seem closely to resemble those of 8. atro- 
rubens, Hess (Hess, Beitrage zur Kenntniss der Decapodenkrebse 
Ost-Australiens, 1865, Taf. vi. fig. 12), but the dactylopodites are 
very short, thick, and tomentose, resembling those of Sesarma 
rotundata, described by the same author. The meropodites are 
rather slender, being about three times as long as broad; their 
anterior margin is armed with an acute spine at the distal end, and 
their outer surface presents a few very small, scattered granules, 
except on the meropodites of the last pair. The posterior mar- 
gin of these joints appears entire, except in the first two pairs of 
legs, in which these margins are a little denticulate near their 
distal end, somewhat as in S. rotundata. The outer surface of the 
other joints is smooth. 
The carpopodites and the propodites have about the same length 
in the first and in the last pair of ambulatory legs, but the latter 
are a little longer than the former in the ambulatory legs of the 
second and third pair. The dactylopodites are very short, thick, 
and closely tomentose, but not at all spinulous, and they terminate 
in an acute point; they are much shorter than the propodites, 
those of the penultimate pair of legs measuring scarcely two 
thirds of the length of the propodites. 
The meropodites bear a few scattered hairs along their pos- 
terior margins; the propodites are a little more hairy, and. 
present a tuft of hairs along the distal half of their posterior 
margins, and the dactylopodites also are clothed with some longer 
hairs among the short down which is found on their anterior 
and posterior margins.
