[Vol. IV, 



A very small specimen ('^), a male 19 mm. in length, taken in company with 

 large typical examples, is in an early post-larval stage. The spines at the antero- 

 lateral angles of the carapace are not developed, submedian carinae are absent except 

 on the last somite, and on the margin of the telson there are numerous minute sub- 

 median denticles and ten or eleven intermediate. A similar but slightly larger example 

 (ff), measuring 2y$ mm., is referred with some doubt to this species. The denticles 

 on the margin of the telson are, as might be expected, fewer in number than in the 

 small example, but in the bifurcate process of the uropods the lobe on the outer face 

 of the long tooth is very much larger than in that specimen or in adults. In both 

 these individuals the inner edge of the process is finely serrate. 



Spirit specimens of 5. gilesi show no characteristic colouring.

 Allied, apparently, to the two preceding species is Jurich' s Squilla minor, des- 

 cribed from two extremely small specimens (165 and 19-5 mm. in length) from 50 

 metres near Zanzibar. According to the description and figures these examples differ 

 from Brooks' adult 5. lata in the following characteristics : — 



1. There are no intermediate carinae on the carapace and no submedian carinae 



on any segment of the post-abdomen except the last. 



2. The rostrum is much wider, a little broader than long. 



3. The eyes are extremely large, their length being about one- third the length of 



the carapace and rostrum. 



4. There is a prominent outstanding lobe at the proximal end of the external 



margin of the raptorial dactylus. 



5. The spine on the ventral surface of the fifth thoracic somite is unusually well- 



developed ; it extends outwards and is visible in dorsal view. 



6. There are three or four submedian denticles on the telson and on either side of 



the median crest there is an oblique row of six short elevations which appear 

 to correspond with the interspaces between the impressed lines in 5. lata.
