192 DE. J. G. DE MAJSr ON THE PODOPHTHALMOtfS 



pointed tips, therefore agree with those of S. Edwardsi, but 

 they are less strongly denticulated along their inner margins, 

 presenting only some small teeth, of which tbe 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 S. 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, beiug 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.
