part of the telson of Petrol. carinipes should be compara- 
tively a little longer and somewhat less distinctly emargi- 
nate on the lateral margins. 
It appears to me very likely that Porc. coccinea Owen 
is identical with Porc. barbata, but I cannot decide this 
question, because Owen makes no mention of the epi- 
branchial tooth, which is moreover not distinctly recog- 
nizable on the figure in the »Voyage of the Blossom.” 
Owen’s example was collected in the Paumotu Archipelago. 
According to Dana, whose specimens were collected at 
the Sandwich Islands, an epibranchial tooth is present, 
and then the identity becomes of course more probable.

Thirty five specimens were collected in the freshwater 
lake of Nefko on the island of Timor, amongst which 
only one single ova-bearing female. 
This species is no doubt, most closely allied to Car. pa-
