All the appendages exclusive of the pleopoda and uropoda are 
present. The lst and 2nd antennæ have about the same form as 
in the lst larval stage of Pandalus borealis (G. O. Sars: Account 
of the postembryonal development of Pandalus borealis .. . .; Report 
Fig. 24. The larva of Pandalus propinquus (?): 
telsou and nropoda of stage 1—5. 
on Norwegian Fishery- and Marine-Investigations, vol. 1, 1900, 
No. 3, PI. 1, ligs. 3—4); the most important difference is that the 
stem of lst antenna has a little joint apically. Also the man- 
dibles and the maxillæ have about the same form (Sars 1. c.,PI. 1, 
ligs. 6—7); through the skin the mandibles and 2nd maxillæ of 
the next stage may be seen. The same agreement will be found 
in regard to lst and 2nd maxilliped (Sars 1. c. figs. 10—12); but 
3rd maxilliped has the usual form and is not dilated as in Pan¬ 
dalus borealis (Sars 1. c. fig. 12); besides it has 7 joints. (1. stage
