204 PALAEMON NEGLECTUS. 



(lis taut from the articulation and there are three or 

 four smaller teeth between both. In the adult male of 

 Pal. lar one observes on the dactylus, between the tooth 

 at the end of the cutting-edge and the articulation, six 

 small, rounded teeth, of which the two or three proximal 

 ones are somewhat more prominent than the following; in 

 the adult male, long 85 mm., from the Battak-Country, 

 however, the dactylus carries in one leg two, in the other 

 (1. c. Fig. 376) four acute teeth, of unequal size, and of 

 which the foremost one is the largest and barely smaller 

 than the 5th tooth at the end of the cutting-edge. In 

 the male specimen from the Mergui Archipelago, described 

 in 1888 under the name of PaL acutirostris, the fingers 

 were armed only with two, respectively three teeth at all. 



In a younger male of PaL neglectus, 58 mm. long, the 

 fingers have still the same form as in Pal. lar, and their 

 teeth are more obtuse. 



To the preceding description may be added that in the 

 adult male of Pal. neglectus the carpus of the 1st pair 

 of legs is just twice as long as the chela.

In 1892, when I was describing the specimens of Pal. 

 neglectus from the Battak-Country, that were referred by me 

 to Pal. equidens Dana, typical specimens of Pal. reunion- 

 nensis were not at my disposal. Nevertheless the latter 

 species was considered by me as identical with that from
