Stomatopoda 

 Five adult Squilla, identified as S. armata Milne-Edwards and confirmed as such by Dr I. Gordon 

 of the British Museum, were taken at St. WS 990, net. o.T.c, depth 128 m. Position: from 25 35' S., 

 14 27' E., to 25 36' S., 14 24' E., off west coast of Africa. 



Occurrence (Stations). WS 1000, 50-0 m., 2 larvae (intermediate stage). WS 1001, 50-0 m., 

 19 larvae (from first pelagic stage to latest seen, presumably stage IX). WS 1001 , 100-50 m., 3 larvae 

 (1 stage IV, 1 stage VII, 1 stage VIII). WS 1002, 50-0 m., 4 larvae (intermediate stages). 



Fig. 6. Squilla armata}, St. WS 1001, 14. iii. 50, 50-0 m. a, alima, first pelagic stage, length 47 mm. ; b, late alima, probably 

 last (rostrum and posterior carapace spine broken), length 20 mm.; c, the same, raptorial claw; d, uropod; e, end of telson. 



Several Stomatopod larvae were obtained in the plankton round about the area at which the adult 

 Squilla armata occurred, and almost certainly belong to this species (Fig. 6). The oldest larva had the 

 raptorial claw with seven teeth, some of which were still covered but were quite distinct. The uropods 

 are also very like this species. The oldest larva, c. 20 mm. long, is either at the last or penultimate 

 stage and no older specimens were seen. The other stages range from the first pelagic stage, through 

 several intermediate stages to this late stage. They correspond very closely as a series to those of
