the carapace and on the antennal peduncle are conspicuous and of a fine dark-blue, the pale 

 lateral band, that narrows from before backward, is white and the more narrow^ bands that 

 border the cardiac region laterally and, curving obliquely backward, separate the intestinal 

 region from the branchial regions, are also white. The dark band on the posterior margin of 

 the abdominal somites is of the same blue, while the white stria on this band is rather broad. 

 The crround-colour of the thoracic legs is violaceous, the lonoitudinal striae whitish. The colo- 

 ration of this specimen is just the same as that of the two young specimens from the Bay of 

 Bima, Sumbawa, which, described by me in 1892 (1. c.) under the name of Pa/, fasciaius Fabr., 

 are lying again before me, except that in the younger of the two the dark flecks on the 

 carapace and the antennal peduncles are dark-green instead of dark-blue. The carapace is as 

 spinulose as in the other female and the transverse interrupted grooves on the 2"'^ and 3''^ 

 tergum show the same characters. The internal antennae of this young specimen are 100 mm. 

 long, 4-times as long as the carapace; the peduncle, 25 mm. long, reaches by its terminal 

 joint beyond that of the outer antennae. The flagellum of the exopodite of the 2"*^ maxillipeds 

 is very small. The 3''*^ jaair of legs, the longest, extend by their terminal joint beyond the 

 antennal peduncle. The spine at the coxa of the 5"^ legs is still rudimentary. The abdominal 

 appendages agree with those of the larger female, but the endopodite of all the somites appears 

 comparatively much smaller. 



All the other specimens are much smaller than the just described female. 



The larger specimen from Stat. 234, a male, in which the genital apertures are still 

 inconspicuous, is 35 mm. long, the blue has changed in a rufous colour on the body and in a 

 rosy one on the legs, the W-shaped, white figure on the carapace is well developed, the blue 

 band on the posterior margin of the abdominal somites is rosy and the white stria is rather 

 broad and separates the rosy band from the transverse, interrupted grooves that are quite 

 distinct on the 2""^ and 3"' terga, while even a trace of a groove, though glabrous, is visible 

 on the 4'^^ The other specimen, 26 mm. long, is also a male, according to the pleopods, the 

 genital a^aertures are still wanting. The white W-shaped figure is conspicuous on the greenish 

 ground-colour of the carapace, the dark band on the posterior margin of the abdominal somites 

 is violet and separated by a broad white band from the rest of the terga ; interrupted grooves 

 on the 2°<i and 3'"'' distinct. 



The largest specimen from Ambon is a male long 39 mm. The grooves are distinct on 

 the 2"<i and 3'''^ terga. The internal antennae are 43 mm. long, 3-times as long as the carapace, 

 their peduncle, long \2^\„ mm., projects by its greater half beyond the distal end of the antennal 

 peduncle. The two other individuals are 24 and 25 mm. long and agree with the two young 

 specimens from the Java Sea, which I have described in 1896 (I.e.) as Paliintriis sp., mentioned 

 three years later by Borradaile (I.e.) under the name oi Pamtl. deinani\ traces of a transverse, 

 interrupted groove are, however, visible on the 2"'^ somite of the smaller specimen. The 

 longitudinal lines on the thoracic legs are, however, in the specimens from Ambon more or 

 less discernible, w'hile they had fully disappeared in the specimens from the Java Sea; the 

 ground-colour of the latter, which are again lying before me, is yellow-brown, in the specimens 

 from Ambon it is a darker brown, which is red-brown on the carapace.
