Systellaspis debilis (A. M.-Edw.), var. indica n. 



Stat. 161. August 17. 1° 10'.5 S., 130° 9' E. Halmaheira Sea. 798 m. 

 Bottom muddy sand. 1 egg-bearing female. 



This specimen differs from the typical atlantic species, as described 

 by Stanley Kemp in: „Fisheries, Ireland, Sci. Invest., 1908, I. [1910], 

 p. 59, PL YI, figs. 1 — 15" by the following. The rostrum, one and a 

 half as long as the carapace, is strongly curved upward, so that the 

 vertical distance between the apex of the rostrum and the upper margin 

 of the carapace measures almost two-thirds the height of the latter. 

 The antennular peduncle reaches almost to the middle of the antennal 

 scale, viz. to -|-§- the length of the latter. The propodus (5 mm.) of the 

 legs of the 3 r d pair is but little more than twice as long as the carpus 

 (2'/ 3 mm.) and the dactylus measures about four-fifths the length of the 

 propodus. 



Length 94 mm. from apex of rostrum to end of telson.
