Station 3387. 127 fathoms. 2 males. 
Both specimens are adult, the larger measuring 58.5 < 105 mm. 
(including the lateral spines). The more prominent parts of the carapace 
rise into small tubercles here and there, to the number of about twenty-five. 
The position of some of these tubercles appears to be indicated by reddish 
spots in Milne Edwards and Lueas’s figure of this species.* In the “ Alba- 
tross” specimens the teeth of the antero-lateral margin are sharper and 
smaller than in the figure, the meri of the ambulatory appendages narrower, 
and the dactyli are not expanded near their tips. 
Platymera gaudichaudii has hitherto been known as a Chilean species. 
Through the kindness of Miss Rathbun I have had an opportunity to 
examine specimens of Plalymera californiensis,¢ recently described by her. 
They are identical with the specimens which I have referred to P. gaudi- 
chaudii. 1 do not think that the very slight discrepancies between these 
specimens and the figures in D’Orbigny’s Atlas warrant their separation, 
especially as neither Miss Rathbun nor I have had specimens from Chile 
for comparison. The differences between our specimens and the figures 
might well arise from a slight inaccuracy of the draughtsman. The types 
of P. californiensis were dredged off the coast of California, lat. 832° 22’ 30” N. 
to 37° 43° 20” N., in 26-204 fathoins.
