72 ALLAN HANCOCK FOUNDATION OCCASIONAL PAPERS
The carpus is longer than the palm, the ischium is about as long as the
merus. The last three legs are smooth. The third fails to reach the end
of the scaphocerite, the fifth reaches beyond the middle of that scale.
An ovigerous female (73 mm) has the 2nd chelae of about equal
size, reaching with the larger part of the carpus beyond the scaphocerite.
The relations between the joints of the legs are as in the smaller leg
of the male. Otherwise it is just like the adult male, only the spinulation
of the last 3 legs is less strong, and there is no pubescence on the merus
of these legs.
Size: The largest male at my disposal measures 135 mm. An
ovigerous female is 73 mm long. The eggs are numerous and small being
0.35 to 0.50 mm in diameter.
Colour: Notes on the colour of living specimens of this species are
made by Dr. Waldo L. Schmitt from material from Ilha Sao Sebastiao,
S. Brazil during his 1925 expedition to S. America. There are two
strongly different kind of colour types in this species. One form has the
body very dark brown (black brown) on the back, tinged with clearer
brown elsewhere. There are longitudinal lemon yellow stripes on the
body. One of these stripes runs just along the bases of the upper teeth
of the rostrum, the teeth themselves being brown. The carapace is
decorated with 1 median and at each side with 3 lateral stripes. The
median line ends posteriorly in a cross-like figure. Of the 3 lateral stripes
the 2 upper start from the same point on the posterior margin of the
carapace, the upper extending towards the posterior margin of the orbit,
the other to the antennal spine. The lower (third) yellow band is
separated from the lower margin of the carapace by a transparent hazel-
coloured region. The abdomen has a median and at both sides a sub-
median stripe of yellow. A yellow spot moreover is present at the base
of the telson, an elongate oblique spot on the uropodal endopods and a
small spot near the base of the final tooth of the exopods. The lower
lateral stripe of the carapace and the submedian stripes of the abdomen
are bright yellow, all other stripes are of a fainter colour and marked
with dark spots. The tailfan is dark dragon's blood red, darker at the
base, but transparent. The scaphocerite has the spine clear, with a violet
line along the inner side, ending maroon purple; the rest of the lamella
is coloured wine purple. The flagella are colourless. The legs are dragon's
blood red, and the large chela probably purple.
The other type has the body translucent light pea green with black
blue-green line markings. The hairs between the rostral spines are orange
ochraceous. The carapace has tracings of the blue black green. Further-
