of the carapace are little distinct, especially the post-antennular, though in a dry condition they 

 are appreciable, as Spence Bate has already remarked. 



As regards the appendages I may add the following. The scaphognathite (Fig. 44 «) 

 is broadly rounded posteriorly. In the ova-bearing female the external ma.xillipeds reach to the 

 obtuse tip of the antennal scale, their exopodite is well-developed and extends to beyond the 

 middle of the antepenultimate joint. The legs of the i*' pair (Fig. 44 (^j are much shorter, 

 reaching only to the far end of the antennal peduncle, while those of the 2°'' (Fig. 44 r, 440', 

 44^) are as long as the external maxillipeds; the peraeopods of the 3'''^ pair extend by the 

 dactyli beyond the antennal scale, the following gradually diminish in length, so that the s'** 

 pair do not yet reach to the tip of the scale. The propodi (3,9 mm.) of the 3^'' legs (Fig. 44/) 

 are nearly twice as long as the carpus (2 mm.) and the dactyli (1,85 mm.) are almost half as 

 long as the propodi, that are very slender and slightly curved, hollowing legs like the third. 



Epipodites on all the peraeopods well-developed, except on the last pair. 



The form from the western Indian Archipelago should perhaps be distinguished as a 

 variety longirostris from the typical species, that occurs in the Arafura Sea and in the seas 

 south of New Guinea : I do not venture to decide this question, because only one young 

 specimen of the typical species has been collected. 



General distribution: Arafura Sea, near Torres Strait (Spence Bate); Gulf of 

 Martaban (Henderson); Red Sea (Balss).

The two specimens from Stat. 1 64 are not yet adult and bear no eggs. The carapace 

 of the larger is 3,7 mm. long, the rostrum 6,2 mm., 5"* abdominal somite 1,25 mm., 6''^ 2,8 mm., 

 telson 2,8 mm.; in the other the rostrum is broken off at the far end of the basal antennular 

 article, the carapace is 3,55 mm. long, the 5"" abdominal somite 1,2 mm., 6''' 2,84 mm., telson 

 2,6 mm. The rostrum of the larger specimen is therefore a little more than one and a half as 

 long as the carapace and agrees with the figure 16 of the quoted paper. We read in it about 

 the carapace: "von Stacheln sind nur der Antennal- und der Branchiostegaldorn vorhanden", 

 the carapace, however, is also armed with a well-developed supraorbital spine; 

 the three spines are nearly of the same size. In Fig. 17 of the original paper the supraorbital 

 .spine is figured, but it has been omitted in Fig. 16. The outer orbital angle appears as a 

 prominent truncate process, that is somewhat narrowed at its base. With regard to the abdomen 

 I would remark, that the terga both of the 4''' and of the 5"^ somite (P'ig. 45^') are armed on their 

 posterior margin at each side with a spine and that there is also a spine on the posterior margin 

 of the pleura of the 5''^ somite; the two first mentioned spines are of the same size, the last
