green spot on each side bordered with a yellow ring ; penultimate joint of raptorial 
limbs bordered with green and yellow ; dactyli rose-coloured. 
There is only a single small specimen of P. oculata in the Indian Museum :—

Pseudosquilla oculata has been recorded from Samoa (de Man) ; Macclesfield Bank, 
China Seas (Pocock) and from Mauritius (Richters, Bigelow). _In the Atlantic it is 
known from the Cape Verde Is. (Brullé) and from Madeira (Miers).

P. megalophthalma, of which I have seen no specimens, is related to P. oculata, 
and possesses the same number of carinae on the telson. It may be distinguished by 
the following characters :— 
1. The rostrum is broadly heart-shaped, truncated at the base, and is interme- 
diate in form between that of P. ornata and P. oculata. 
2. The eyes are large and triangular. The conical portion is set transversely on 
the stalk and its breadth is considerably greater than the length of the whole 
organ. 
3. In addition to the usual six spines on the last abdominal somite there is a small 
one on the inner side of each of the intermediates. 
4. On the dorsal surface of the telson the first lateral carinae' are not parallel 
as in P. oculata, but are posteriorly divergent and are continued to the tips 
of the lateral spines. 
5. The distal segment of the exopodite of the uropods is larger than in P. oculata 
or P. ornata. 
The raptorial claw also is longer and more slender, and, when folded, extends from 
the apex of the eyes to the most posterior part of the carapace. 
In the type specimen the postero-lateral angles of the last five abdominal somites 
are spinous; only the last three in the specimens recorded by Nobili. The outer of the 
two spines of the bifurcate process of the uropod is longer than the inner in Bigelow’s 
example, but in Nobili’s specimens the two are subequal. 
The colouring, according to Nobili is characteristic :—‘‘ Sur la carapace il y a 
une grosse tache oculiforme noire, entourée par une ligne jaunatre. I,es angles posté- 
rieurs du cinquiéme et du sixiéme segment de l’abdomen sont aussi colorés de noir avec 
une ligne jaundtre. Ie dos du doigt des pattes ravisseuses, et les épines et les crétes 
du telson ont une couleur violette.’’ 
Bigelow’s specimen, which is 68 mm. in length, was found at Mauritius, the five 
smaller examples recorded by Nobili were taken at Obock in the Red Sea and at Dijji- 
bouti. 
' It is possible that these carinae are not in reality first laterals, but are homologous with the 
second lateral carinae found in P, dofleini, pilaensis and cerisii. No figure of the telson is extant.
