the terminal spine appears more slender and reaches until the i st pair of legs. This specimen 

 bears some resemblance to Sic. trispinosa de Man, but in the latter the i st carapacial tooth is 

 much shorter, not long er than the 2 nd , the pleura of the i st abdominal somite show two 

 transverse furrows and probably will the male of Sic. parvala also differ.

Stat. 7. March 11. 7°55'.5S., 1 14 26' E. Near reef of Batjulmati (Java). 15 m. and more. 

 Bottom coral and stones. 1 female. 



This female has the same size as that from the south coast of Manipa-island, described 

 by me in 191 1, because it is also 17 mm. long (carapace, rostrum included, 6,2 mm., abdomen 

 10,8 mm.). The rostrum, which reaches to the middle of 2 nd antennular article, slightly directed 

 upward, is armed above with five teeth; the i st stands on the carapace like in the female 

 from Manipa-island and the apex of the tooth reaches just beyond the orbital margin ; this 

 tooth and the two following are of the same size, but the 4 th and the 5 th are a little smaller 

 and the 5 th that is slightly curved downward, projects not only (Fig. 6) beyond the small acute apex 

 of the rostrum but even a little beyond the tooth of the lower margin. Near the lower margin 

 at either side, on the distal half of the rostrum, four short spiniform setae are implanted. 

 The distinctly narrowing rostrum appears in a lateral view 0,7 mm. broad at base, while the 

 tip is 0,3 mm. broad, being near the base more than twice as broad as on the level of the 

 4 ,h rostral tooth. In the female from Manipa-island the upper margin presented only four 

 teeth and between the broken apex of the rostrum and the tooth of the lower margin a 

 rounded prominence was observed, tipped with a tuft of setae. The two other carapacial teeth 

 agree with my figure 41, the distance between their apices being slightly longer than the 

 distance between the apex of the 2 nd and that of the i st rostral tooth. 



Outer orbital angle angular, obtuse ; in the Challenger type that was 30 mm. long, 

 the angle was spiniform, "produced to a point". 



The abdomen agrees with the female from Manipa-island, but of the two small acute 

 teeth on the postero-inferior angle of the 4* pleura the upper is much larger than the lower. 

 External maxillipeds a little shorter than the antennal scale. Peraeopods of the i st pair bispinose. 

 The spine of the thelycum (Fig. 6a) reaches to the posterior border of the 2 nd legs. Median spines 

 on the abdominal sterna well-developed.
