PLATE 2 
Fig. 1. A photograph which indicates the comparative smallness of the newly regenerated cheliped 
(left side) after the first post-regenerational ecdysis. 
Fig. 2. A photograph which shows the manner of papilla formation and regeneration of a dactyl located 
on a cheliped. 
Fig. 3. A photograph which discloses the "sponge” of an ovigerous female. Note the comparative size 
of the ova, and the basket-like arrangement provided by the exopoditic and tergal setae. 
Fig. 4. A photograph which shows the megalops of P. crassipes in dorsal view. Note particularly the 
comparatively large eyes and long ambulatory appendages bearing hooked dactylar spines. 
Fig. 5. A photomicrograph which shows empty egg capsules attached to the endopoditic setae of the pleo- 
pods of a recent exuvia. Close examination will reveal the twisted funiculi. 
Fig. 6. A photograph which shows the ventral aspect of a female crab with the abdomen extended. Note 
the vulvae near the mid-line of the sixth sternite and the four pairs of abdominal pleopods.
