 Measurements. — Largest male: length 23.0 mm, width 42.5 mm, 

 cheliped 36.0 mm, chela 20.0 mm, dactyl 11.9 mm; largest female: length 

 20.7 mm, width 38.3. 



Color in life. — Carapace claret brown shading into dragon's blood red 

 on marginal lobes. Appendages dragon's blood red with a band of claret 

 brown on each segment. Chelae black. Dactyls of walking legs white, nail 

 yellow. 



Habitat. — Pocillopora coral clumps. 

 Depth. — Shoal water. 



Remarks. — C. cinctimanus belongs to the Pocillopora coral fauna, 

 and, when occasional specimens are encountered under rocks at low tide 

 level, a diligent search seldom fails to reveal coral nearby. 



Growth. — An interesting growth series has been aranged, showing 

 complete intergradation between pure white young and pure red adult 

 with black banded wrists. The color appears at first as a delicate pink 

 which gradually deepens, rather than as a series of widening bands, as 

 in Actaea dovit^tim^son (pi. 79, fig. 2). The 2.7 mm specimen described 

 by Crane (1937) was thought to be of the latter species until a single 

 banded Carpilodes was noted among Velero III collections also.
