It would appear from these observations that the young of 

 Nephrops andamanicus is hatched in a form not essentially 

 different from that of the adult, and not considerably divergent 

 from that of the larva of Nephrops normegicua figured by 

 Professor Sars.

Several fine specimens from Station 115, 188 to 220 

 fathoms, including an ovigerous female, the eggs of which 

 still consist almost entirely of food-yolk. The eggs of this 

 species are very much smaller and more numerous than those 

 of Nephrops Carpenteri, W.-M., briefly described in P. A. 

 S. B. 1885, p. 72.

I refer to this species a young male from Station 114, 

 922 fathoms, which differs from the specimens taken in the 

 Laccadive Sea only in having the third and fourth abdominal 

 pleurae, as well as the second, armed in front with a spine.

The late Professor Wood-Mason had noted that " in the 

 male the olfactory branch of the antonnules is much thicker 

 than it is in the female." In the Introduction to this paper 

 (Ann. & "Mag. Nat. Hist., July 1891, p. 16) this species was 

 stated to be luminous, in mistake for a species of Pentacheles 

 (P. phosphorus).
