the eyes, of the telson, and of the lateral margins of the sixth and seventh thoracic 
somites, there appears to be the closest resemblance between the two forms. 
The colour is as follows :—‘‘ Abdomen olive-green, mottled with paler green ; 
carapace greenish brown, mottled with cream ; raptorial claw brown (dactylus purple) 
mottled with cream.’’ ‘There is also a pair of large dark spots on the carapace, not 
surrounded by a white ring. 
The only known specimen, a male, 88 mm. in length, was found at Rotuma, Fiji Is.

This species is also a close ally of P. ovnata, but is readily distinguished from it 
and from both the preceding species by the possession of an additional pair of short 
longitudinal carinae on the telson. These carinae, the first laterals, are parallel 
and terminate behind the base of the intermediate marginal teeth. 
In other respects the points of distinction between P. oculata and P. ornata are 
few :— 
1. The rostrum is provided with an apical spine.! 
2. The eyes are flattened as in P. orvnata, but are shorter and more thick-set ; the 
cornea is transverse, very noticeably wider than the stalk, and its greatest 
breadth is almost equal to the length of the whole organ. 
3. The ultimate segment of the exopod is even smaller than in P. oynata, being much 
less than half the length of the preceding segment. It is outreached both by 
the distal external spine of the basal segment and by the outer (and longer) 
spine of the bifurcate process. | 
De Man has compared the type specimen of this species, which was found at the 
Cape Verde Is., with two from Samoa, and notes that the only differences he can find 
are that in the Pacific examples the eye-peduncles are a little more dilated at the 
distal end and that the rostrum is slightly more transverse with the apical spine a trifle 
longer. 
According to Miers the colour of this species is described by Webb and Berthelot 
as being of a green colour, with numerous yellow rounded spots; there is a large round 
' This spine in the single specimen examined, is much larger than is indicated in Miers’ figure.
