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 : — 

 % ^ß Society Is. Otago Museum. 1 2 , 27 mm. 



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. omata 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 l 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. omata. 



The raptorial claw also is longer and more slender, and, when folded, extends from 

 the apex of the eyes to tjie 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 jaunâtre. Les angles posté- 

 rieurs du cinquième et du sixième segment de l'abdomen sont aussi colorés de noir avec 

 une ligne jaunâtre. L,e dos du doigt des pattes ravisseuses, et les épines et les crêtes 

 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 Dji- 

 bouti. 



1 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.
