Chlorot. spinicauda is found in rather shallow water between 30 and 51 fathoms and 

 seems to be a rare species; Chlorot. incertus was taken at a depth of 150 fathoms, Chlorot. 

 crassicomis, the type species, from 80 to 326 fathoms, the variety andamanensis at 185, 

 Chlorot. Novae-Zealandiae (Borr.), finally, at a depth of 70 fathoms.

Stat. 51. April 19. Madura-bay and other localities in the southern part of Molo-strait. 



54 — 90 m. Bottom fine grey sand ; coarse sand with shells and stones. 1 full- 



grown, egg-laden female. 

 Stat. 153. August 14. o°3'.8N., I30°24'.3E. N.W.-coast of Waigeu-island. 141 m. Bottom 



fine and coarse sand with dead shells. 1 young male.

Bottom sand with dead shells. 1 male. 



The specimens from the Stations 5 1 and 204 perfectly agree with the detailed description ') 

 of the specimen from Ternate, described in 1902, except in some particulars ovving to their full 

 development; the specimen from Ternate was very young, as I already suggested in 1902, but 

 the male from Stat. 204 is 25 mm. long and the egg-laden female from Stat. 51 measures 

 nearly 36 mm. from apex of rostrum to tip of telson. Carapace and rostrum, taken together, 

 are in these adult specimens a little shorter than the abdomen : in the male the carapace 

 measures 6 mm., the rostrum 4,9 mm., the abdomen 14 mm., in the female these numbers are, 

 in the same succession, 8 mm., 6,75 mm. and 20,85 mm - While the carapace of the male 

 resembles the figure 59 of the originai description, as regards the proportion between length 

 and height, the carapace being in the male from Stat. 204 6 mm. long and 4,9 mm. high, in 

 the large full-grown female the carapace appears comparatively much higher, namely 8 mm. 

 long and 7,5 mm. high. Owïng to the greater height of the carapace the upper border of the 

 rostrum appears in the full-grown female more strongly turned downward than in the 

 young specimen from Ternate and the male from Stat. 204, but the lower margin runs like in 

 these specimens-, both in the male and in the female the rostrum is 1-dentate and in both the 

 3 rd tooth stands above the orbital margin; also, as regards the general form, the rostrum 

 resembles the figures 59 and 59a. The small tubercle on the middle of the upper border of 

 the carapace is in the female quite distinct and there is another similar, small tubercle at the 

 base of the i st tooth; in the male both tubercles are less developed. Behind the tubercle the 

 cardiac region appears a little uneven, more distinctly in the larger female than in the male. 

 In both specimens the orbital spine reaches to the cornea of the eyes and is much longer 

 than the branchiostegal spine, which is not carinate: according to the originai description in 

 the young specimen from Ternate this spine should have been carinate. 



Antero-inferior angle of carapace rounded, lower margin carinate.
