The abdomen of the male accords with the original description, but the median spine 

 on the posterior margin of the 6 lh somite is only half as long as the lateral and this is 

 also the case in the female. The abdomen of the female differs, moreover, from that of the 

 male by the strong development of the pleura of the i st and 2 nd somite and by the 

 reduction of their spines, that are very small, much smaller than in the male. While in 

 the male the anterior margin of the pleura of the i st somite is straight or, like in the young 

 specimen from Ternate, even slightly concave and does not reach over the carapace, in the 

 female the pleura of the i st somite are strongly curved anteriorly, covering the 

 adjacent part of the carapace; the 3 rd and following somites agree with those of 

 the male. 



The ocellus on the eyestalk of Chlorot. incertus is described as independent, in Chlorot. 

 spinicauda it is not circular but o val and transverse and its anterior margin lies against 

 the cornea ; the cornea is distinctly broader and nearly as long, though not shorter than the 

 rest of the ophthalmopod ; in the type species, Chlorot. crassicornis, an ocellus is wanting. 



The antennular flagella are subequal and a little longer than the carapace ; the thickened 

 part of the outer flagellum reaches almost to the tip of the antennal scale. The antennal 

 flagellum of the male, though not quite complete, is 20 mm. long and will, no doubt, once 

 prove to be as long as the body. 



The molar process of the mandible (Fig. 46 «) of the male is truncate at the tip, the 

 margins are not toothed, but somewhat lobate ; the incisor process terminates in 5 acute teeth, 

 of which the two lateral are twice as large as the three others that are equal. The palp is 

 (Fig. 46^) three-jointed, like in Chlorot. crassicornis (Th. R. R. Stebbing, South African 

 Crustacea, Part VII, 1914, p. 42, PI. XI, fig. m)\ the i st or basal joint is 0,5 mm. long, the 

 2 nd 0,22 mm., half as long as the i st , the 3 rd or terminal 0,63 mm., nearly 3-times as long as 

 the 2 nd . The joints are flattened, the 3 rd about 2 1 / 3 -times as long as wide at base, narrowing 

 regularly to the obtuse tip and the margins are fringed with setae. Stebbing (1. c.) remarks, 

 that the incisor process of the mandible of Chlorot. incertus was figured by Spence Bate 

 (Challenger Macrura, PI. CXVI, Fig. 1 d) as a sort of stiletto : concerning this I would say, 

 that in a certain position of the mandible this process shows the same form in Chlorot. spini- 

 cauda, when namely the incisor is looked at from the lateral edge. 



The emarginate tip of the palp of the i st maxilla (Fig. 46 f) bears at one angle two setae 

 of unequal length, at the other angle one; the middle branch shows a characteristic notch 

 o r i n cis i o n , but seems to have been damaged by the operation ; the third branch is curved 

 and fringed with stiff setae, partly feathered and spiniform. 



Unfortunately, also in consequence of the operation, the posterior half of the scapho- 

 gnathite has been cut off; of the two inner distal lobes that project far beyond the basal lobe, 

 the anterior is one and a half as long as the posterior and rounded anteriorly. 



The second maxillipeds (Fig. 46^, 46c) differ from those of Chlorot. crassicornis and 

 incertus by the shape of the / th or terminal joint. While in these two species it is applied as 

 a strip along a great part of the outer margin of the 6 th , in Chlorot. spinicauda the / th joint 

 is attached near the posterior extremity of that margin, its length being hardly one-fourth
