CALLIANASSA AUDAX, 220 
NOTE XV. 
ON TWO NEW SPECIES OF DECAPOD CRUSTACEA 
BY 
Dr. J. G. DE MAN. 
Callianassa audaz, n. sp. 
Two females, collected in 1892 in the Strait of Malacca 
and presented by Mr. Tydeman to the Zoological Museum 
of the University of Utrecht, belong to a new species, 
much resembling Call. gigas Dana in its outer appearance 
and related also to Call. novae-britanniae Borr. from New 
Britain, to Call. kraussi Stebb. from the Cape of Good Hope 
and to Call. mauritiana Miers from Mauritius. 
Sutures of the carapace deep. Rostrum minute, measuring 
one-sixth of the length of the eye-stalks, broader at its base 
than long and rather obtuse; a still smaller, rounded 
projection between the eye-stalk and the antennal peduncle. 
Eye-stalks almost as long as basal antennular article, about 
twice as long as broad at their base, with subacute tips; 
corneae black, situated in the middle at the outer side. 
Second antennular article one and a half as long as thick, 
third article one-fourth longer than the second; flagella of 
equal length, a little more than one and a half as long 
as the peduncle. External antennae one and a half as long 
as the inner and as the carapace, antennal peduncle a 
little longer than that of the inner antennae. External 
maxillipeds resembling those of Glypturus Branneri Rathb. 
(vide: Proc. Wash. Acad. Sc. II, 1900, p. 150, pl. VIII, 
fig. 7), but the carpus distinctly less wide than the propodus; 
no spinous crest on the inner face of the ischium, propo- 
dus a little wider than long, dactylus slightly compressed.
