grey mud, upper layer more liquid and brown mud. 2 young specimens. 

 The numerous specimens fully agree with the quoted descriptions and fiaures but it 

 must be observed that the dactyli of the three posterior legs, described by CoL Alcock as 

 "very short", are indeed rather long (J. Wood-Mason, I.e. Fig. 6), measuring one-third of 

 the propod. (E.g. 39/, 39 .). Form, length and direction of the rostrum vary rather much like 

 also the number of teeth with which the margins are armed (confer the figures). The carapacial 

 canna, of which the height also varies considerably, is usually armed with 6 teeth of which 

 the 6t'^ stands before the orbital margin, like in Wood-Mason's figure, rarely with 7 or v in 

 case of 7 teeth, five or six, rarely four, stand on the carapace behind the posterior margin in 

 case of 5 teeth, four. The upper margin of the rostrum proper bears usuallv 2 or 3"teeth, 

 rarely i or 4, and these teeth are much smaller than those of the carapacial carina The lower 

 margm has usually 12-.4 teeth, rarely 11 or 15, in only one adult specimen ,0 teeth were 

 observed, in another 9, in a third 8 and in an adult male from Stat. 74 the lower marc^in 

 bears but 6 teeth; the ventral teeth gradually decrease in size anteriorly and the 2 or 3 foremost 

 ones are rudimentary. The rostrum is more o, less strongly upcurved, so that the apex is some- 

 times, especially m younger individuals, situated above the level of the teeth of the carapace 

 sometimes just as high, or below it. The outer aspect of the specimens appears therefore 

 sometimes so different, that one is inclined to consider them as different species. 



In an adult male from Stat. 74, of which the carapace measures 3^ mm. from the orbital 

 to the posterior margin and the rostrum 21,5 mm., the fifth abdominal somite, measured dorsally 

 proves to be 9 mm. long, the sixth 12 mm., the telson 2. mm., the terminal spines e.xcluded' 

 and the telson is still i mm. shorter than the uropods of the caudal fan ; in the largest ova-
