Stat. 240. November 22 till December 1. Banda. Lithothamnion-bank in 18 — 36 m. 1 young 

 specimen. 



The two specimens from Stat. 51 are 10 mm. long, that from Bancla 7 mm. In one 

 specimen from Madura-bay the rostrum, somewhat shorter than the orbital spines, reaches only 

 to the middle of the visible part of first antennular article ; the lower spine of the basicerite is 

 slightly directed outward and is longer than the slightly divergent orbital spines, but does not 

 attain the apex of first antennular article. In the other specimen the orbital spines diverge more 

 outward, more than in Coutière's figure 4 (1. c); they hardly reach the middle of the visible 

 part of the first antennular article, whereas the rostrum, distinctly shorter, extends to the 

 2 nd third part of the latter. The stylocerite reaches to the end of first article and the lower spine 

 of the basicerite is much shorter than the stylocerite, though reaching beyond the orbital spines. 

 In this specimen the merus of third legs, which is armed with 5 spinules, is 3,7-times as long 

 as broad, the carpus is 2,3-times as long as thick and the propodus which bears 8 spinules 

 on its posterior margin, is 5,85-times as long as wide; as regards their relative dimensions, 

 we must remark that the merus is 2,56-times, the propodus 2,23-times as long as the carpus. 

 The dactylus which fully accords with Fig. \c' of the original description, measures one-fourth 

 of the propodus and is just twice as long as broad at its base, when its length is measured 

 from the propodal articulation, along the anterior margin, to the tip of the dorsal hook. Merus 

 of fourth legs with 2 spinules, 3,73-times as long as wide; carpus 2,2-times as long as thick; 

 propodus with 8 spinules, 5,5-times as long as wide; dactylus as in the third legs. The merus 

 is 2,3-times, the propodus 2,2-times as long as the carpus. 



The slight differences, presented by these two specimens as regards the length and the 

 direction of the orbital spines and of the rostrum, are considered as individu al, because in 

 the specimen taken at Banda these three spines fully accord with the type (Coutière, 1. c. Fig. 4); 

 the rostral and the orbital spines are distinctly curved upward, especially in the larger specimens 

 from Stat. 5 1 . 



In the young specimen from Banda the merus of third legs with its 4 or 5 spinules 

 appears somewhat more slender, viz. 4,3-times as long as wide; the carpus is 2,3-times as long 

 as thick, the propodus, with 7 spinules, appears 6,2-times as long as wide; dactylus as in the 

 preceding specimen. 



The proportion between length and width of these joints, especially of the propodus, 

 proves to be somewhat variable, just as in the variety bandaensis. 



The large cheliped fully resembles that of Syn. ncomeris (J. G. de Man, in: Zoolog. 

 Jahrb. X, Abth. f. Syst. 1897, PI. 35, Fig. 61a). 



In the other specimen from Stat. 51 the telson appears 2,66-times as long as the 

 posterior margin is wide. The anterior pair of spinules, which are o, 14 mm. long, are inserted 

 a little in front of the middle, the posterior pair one and a half as far distant from the posterior 

 margin as from the anterior pair. In the young individual from Banda the proportion between 

 the length of the telson and the width of the posterior margin is 2,56; the arrangement of 

 the spinules, long 0,12 mm., on the upper surface is the same as in the preceding specimen. 



General distribution: Maldive Archipelago (Coutière) ; Mangarewa, Tearia (Nobili).
