The specimens agree with Brooks's Pacific examples iu the points 

 in which the latter differ from his West Indian ones.

8. PsEUDOSQOiLLA oxYRHYNCHA, sp. n. (Plate VI. figs. 9, 9 a~d.) 

 Definition. — " A Fseudosquilla with broad, club-shaped eyes ; 



rostrum transverse with a delicate median spine ; dactylus of the 

 raptorial claw with three teeth (including the terminal tooth) ; manus 

 of the raptorial claw with three movable spines ; two large dark 

 spots on the carapace not surrounded by a white ring ; lateral 

 process on the first free thoracic segment wanting, on the second 

 and third truncate, on the fourth subacute ; basal prolongation of 

 the uropods ending in two spines ; telson with median crest and 

 six other carinse (including those of the lateral margins), the 

 carinse immediately lateral to the crest being small and serrated." 



Colour. Abdomen olive-green, mottled with paler green; carapace 

 greenish brown, mottled with cream ; raptorial claw brown (dacty- 

 lus purple), mottled with cream. 



Length of the single ( c? ) specimen 88 mm. from tip of rostral 

 spine to bottom of notch between sub median spines of telson. 



This species is intermediate between P. oculata BruUe and 

 P. ornata Miers. It resembles the former in the presence of a 

 small median spine on the rostrum, and the latter in having only 

 six carinse on the telson. From both it differs in the absence of 

 definite eye-spots on the carapace ; these being represented by two 

 irregular dark marks, not surrounded by lighter rings,

9. Ltsiosquilia maculata (Fabr.). 



Squilla maculata, Fabricius, Ent. Syst. t. iii. pt. i. p. 511 (1793) ;

 (1837). 



Lijsiosquilla maculata, Miers, P. Z. S. 1877, p. 138 ; id. Ann. Mag. 

 Nat. Hist. 5, v. p. 5, pi. i. figs. 1 and 2 (1880) ; Brooks, ' Challenger ' 

 Stomatopoda, p. 45, pi. x. figs. 1-7 (1886). 



The marked difference observed by Miers (Ann. Mag. loc. cit.) 

 and by Brooks in the single females they were able to examine 

 holds good for the present specimens, the spines arming the inner 

 margin being, in the male, long, while in the female they are short, 

 and reduced proximaUy to mere serrations. 



Mr. G-ardiner has been kind enough to furnish me with the 

 following note on the habits of this species : — 



" Lysiosquilla maculata (Fabr.). This species is found in the boat 

 channel at Rotuma. It lives in pairs in tunnels on the sandy 

 bottom. These are sometimes as much as 20 feet long, and usually 

 have two exit holes. Each hole is inhabited by a male and a 

 female, which take up their positions at the two exits, with the 

 dactylus and propodite of the raptorial claw widely extended and
