Fifth leg: Merus about twice as long as broad, with usual sub- 
terminal spine on hinder surface; posterodistal border also spinous. 
Propodus with very numerous small spines (ca. 20). 
Remarks.—This specimen keys out in Stephenson and Hudson 
(1957) as T. picta; however, it is neither 7. picta, the related T. 
wakensis, nor T. philippinensis. It differs in the very large number 
of spines on the posterior border of the propodus of the fifth leg, 
hence the specific name. 
It is probably closest to J. picta but differs in the more rounded 
frontal and inner orbital lobes and in various details of the carapace 
ridging. The protogastric ridges are shorter than in 7. picta, the 
mesogastrics are more distinctly interrupted in the midline and are 
concave anteriorly. There is a broader interruption between the 
the metagastric and epibranchial ridges, and the cardiacs are composed 
of two short, widely separated ridges. The cheliped also differs in 
having longer and sharper spines on the wrist and hand and in having 
squamiform markings on the under surface of the hand.
