PALAEMON REÜNTONNENSIS. 205 



the Battak-Country, apparently because the legs of the second 

 pair of the adult male from that locality bore a great 

 resemblance with the figure of Pal. equidens Heller (in : 

 Sitzungsber. Kais. Akad. Wiss. Wien, 1862, Tab. II, Fig. 44). 

 Through the kindness of the Direction of the Leyden 

 Museum, the two typical male specimens of Pal. reunion- 

 nensis, that were describeil by me in 1879, are now lying 

 before me and they prove at once that this species is 

 different from Pal. neglecius. In my paper of 1879 

 Pal. reuvionnensis was said to be »quite different from 

 Pal. ornatus Oliv.," but I am at present better acquainted 

 with the great variability of Pal. lar Fabr., so that I 

 now come to the conclusion that Pal. reunionnensis ought 

 to be considered as a, probably local, variety of 

 Pal. lar Fabr., distinguished by the legs of the second 

 pair, these being equal and more elongated and by the 

 fact that usually three teeth of the upper border of the 

 rostrum are placed upon the cephalothorax (confer Figs. 1 and 

 5) '). The inferior margin of the rostrum carries 3 or 4 

 teeth. The cephalothorax is smooth and the telson agrees 

 with that of Pal. lar Fabr. The fingers of the second 

 pair of legs agree also fully with typical specimens of 

 Pal. lar as regards their form and toothing (Fig. 3). 



In the adult male, long 130 mm., the legs of the 1st 

 pair extend with one fourth part of the carpus beyond 

 the anteunal scales; the carpus, 19 mm. long, is a little 

 more than twice as long as the chela, that measures 8'/2 ram., 

 just as in Pal. lar. 



Hoffmann's description and figures are inaccurate, as is 

 proved by comparing them with mine.

1) It may be remarked that, in J 902, a specimen of the typical Pal. lar 

 from Patani, on the island of Halraahera, has been described, in which also 

 three teeth were placed upon the cephalothorax (de Man, in: Abhandl. 

 Senckenb. Naturf. Gesellsch. T. XXV, p. 778).
