The inner antennae are 280 mm. lon^-, the peduncle 80 mm., the longer flagellum 

 200 mm.; the shorter flagellum is one and a half as long as the peduncle. The antennular 

 peduncle reaches by its terminal joint beyond the distal end of the peduncle of the outer antennae. 



Lateral spines of the epistome half as long as the middle one. External antennae 610 mm. 

 long, 2-/s-tin''es as long as the body, the peduncle is just as long as that of the inner antennae 

 and just as long as the carapace, viz. 80 mm. 



External maxillipeds (PI. II, fig. -jc) without an exopodite; exopodite of the maxillipeds 

 of the following or 2"^ pair (PI. II, fig. j l>) without a flagellum and reaching the terminal 

 fourth jiart of the outer margin of the mcrus-joint. The oval, flattened flagellum of the i^' pair 

 of maxillipeds is lo-jointed, its greatest width is a little more than '/^ its length. 



The legs of the P' pair reach by their dact\li beyond the 2"'' joint of the antennal 

 peduncle, those of the 2"'' pair arc as long as this jieduncle, while the legs of the 3'''^ pair are 

 the longest of all, extending by half their dactyli beyond the antennal peduncle; the legs 

 of the 4"* pair attain the middle of the 3"', those of the 5''' the middle of the 2"*^ joint of 

 this peduncle. 



The variability of Paiiiil. oj'uatiis^ as regards its coloration, is proved by the young 

 female from Ambon. This specimen is 91 mm. long, the carapace measuring 31 mm., the 

 abdomen 60 mm. The gastric and the cardiac regions until to the transverse furrow near the 

 posterior border are partly dark-green jjarlly verdigris, like also the antennular segment and 

 the inner half of the hepatic area; the outer half of the latter is dark-purple, marbled with 

 some pale lines and there is a yellow fleck that separates the purple and the green portion 

 of the hepatic region. The median regions of the carapace are marbled with pale lines and 

 small spots. The branchial regions mitil the lateral border are yellow like also the po.sterior 

 border of the carapace. The two su|)ra-orbital spines are dark-purple, the proximal half of 

 their anterior margin like also the anterior margin ot the carapace between them are yellow. 

 The sharp spines and teeth on the upper surface of the carapace agree, as regards their 

 number and arrangement, wiili the large male from Makassar, all are yellow except 4 or 5 

 on the inner half of the hepatic regicMi. The i*^' abdominal somite is dark-green with small, 

 ])ale spots, the pleura of the i^' somite also dark-green with cream-coloured extremity and a 

 fleck of the same colour on their internal angle. The 2"'^ to 5*'' terga are honey-coloured; a 

 dark-green, transverse fleck runs along the posterior margin of the 2'"' .somite, extending until 

 the middle of this somite and a much smaller fleck of the same colour runs along the posterior 

 margin of the 3"', whiie ulic posterior margin of the two following somites is also dark. The 

 posterior half of the 6''' tergum, the calcareous parts of the caudal fan and the 2"'' to 6''' pleura 

 show the same dark-green colour and the green parts are everywhere covered with small, pale 

 spots. The two oblique, cream-coloured flecks near the antero-lateral angle of each somite are 

 rather well visible, especially the larger outer one. 



The i-^' joint of the antennular peduncle is dark-green, the two following arc honey- 

 coloured, all with paler extremities; flagella honey-coloured with 3 ])ale rings on the shorter 

 and 5 on the longer. Antennal peduncles dark-blue with fine pale markings; the flagella are 

 proximally of the same colour, iox the greater part they are honey-coloured.
