granules of the hand extend over its under surface. This species 

 forms a passage to Actcea cellulosa. 



ACT^EODES SPONGIOSUS. 



Carapax posticd mx areolatus, areold 2 M subdivisd, superficie, sulcin 

 exceptis, breviter et rigidd velutind, aspectu spongiosd; margine 

 antero-laterali simplicissime* o-dentato, dentibus gracilibw, acutis. 

 Pedes breviter rigideque pubescentes, antici paulo armati. 



Carapax posteriorly hardly areolate, areolet 2M subdivided, surface 

 with a very short, rigid covering of setules, giving it a spongy appear- 

 ance; antero-lateral margin with five simple, slender acute teeth. 

 Feet with a short stiff pubescence, anterior pair somewhat armed 

 on upper side with small pointed tubercles.

Sooloo Sea, or Balabac Passage. 



Length of carapax, two and one-third lines ; greatest breadth, three 

 and a half lines. 



This species has much the aspect of a Pilodius, though somewhat 

 more convex. Like the A. tomentosus, the areolet 2 M is divided 

 longitudinally, and the peculiar stiff and close setules of the surface, 

 looking like a spongy covering, are confined to the surface of the 

 areolets, and do not occur in the intermediate furrows. The front 

 adjoining the front margin (areolet IF), is nearly vertical. The 

 margin posterior to tooth S is not rounded, but instead is nearly 

 straight, as in Pilodius.
