spinules of the 3" 1 pair are placed, close to the lateral margin, nearly on the middle of the 

 telson, at I3 / 38 its length from the base, those of the 4 ,h pair at the posterior third and those 

 of the 5 th pair, finally, are implanted near the lateral borders a little farther distant from the 

 tip than from the 4 th pair: the spinules of the four posterior pairs are as long as those of the 

 foremost pair. 



The otiter uropods, just as long as the inner, are hardly shorter than the telson. The 

 anterior border of the basal joint terminates laterally in an acute spine. The outer margin of 

 the exopodite runs like a S, slightly convex anteriorly and armed here with 3 or 4 small, 

 articulating spinules, slightly concave posteriorly and terminating in a small spine ; at the inner 

 side of this spine on the posterior margin another is observed, that is a little longer though 

 also immobile and next to this a third articulating spine occurs, which is still a little longer. 

 The rounded posterior margin passes with a regular curve into the inner margin and both are 

 fringed with long feathered setae. The inner uropod is anteriorly almost just as broad as the 

 outer but then suddenly narrows, while the outer border curves inward. The outer uropod is 

 almost 3-times as long as wide in the middle, the inner 4-times; both the inner and the outer 

 margin of the inner uropod are fringed with long feathered setae, except at the anterior enlarged 

 part and a few feathered setae are implanted on the anterior half of the upper surface. According 

 to the description of 1902 in the young specimen from Ternate the inner uropod did gradually 

 narrow from before backwards and was only twice as long as wide in the middle. 



The eyepeduncles, half as long as the carapace without the rostrum, extend to a little 

 beyond the middle of basal antennular article; they are twice as long as the eyes are thick 

 and the latter are provided with a small black ocellus, but not with a crown of long hairs as 

 is the case in Stylod. èimaxillaris, according to Dr. Balss (Beitrage zur Naturg. Ostasiens. 

 Ostasiatische Decapoden II. Die Natantia und Reptantia. München 1914, p. 27). There is a 

 small forwardly directed spine on the upper border of the peduncle midway between the base 

 and the cornea. 



The antennular peduncle is nearly as long as the carapace without the rostrum and 

 reaches about to the middle of the latter; the basal joint measures three-fourths the entire length 

 of the peduncle and the stylocerite that is separated from the peduncle by a narrow interspace, 

 is flattened, while its outer margin ends in an acute spine that reaches about to the middle of 

 the peduncle, though it is shorter than the eyestalk. Second joint very short, measuring only 

 Y s or Yo the length of basal article; it is a little broader than long and a spine, which is as 

 long as the joint itself, is implanted at the distal extremity of the outer margin. The 3 rd joint 

 is one and a half as long as the 2 nd and at the far end of the outer margin a similar spine 

 occurs, which is a little longer than that of the 2 nd joint. Inner flagellum 2,7 or 2,8 mm. long, 

 as long as the carapace without the rostrum, hardly reaching beyond the latter; it seems to 

 be composed of 13 or 14 articles and appears narrow and thin when looked at from above, 

 but thicker in a lateral aspect. Outer flagellum a little shorter, much thicker though tapering 

 distally, 1 3-jointed, the 3 or 4 terminal joints appearing narrow when looked at from above ; 

 olfactory filaments well developed, long.
