I young female. 

 Stat. 301. January 30— February i. io°38 S., I23°25'.2E. Pepela-bay, east coast of Rotti- 



island. iS — 45 m. Mud, coral and Lithothamnion. i young female. 



The female from Stat. 301 is 19,5 mm. long, whereas, according to Dr. Nobili, the female 

 attains a length of 40 mm. ; the other specimen is still of smaller size. In neither of the two 

 the eye-shaped, black spot on the carapace nor the white spots on the sides of the abdomen 

 are visible. In the larger specimen the carapace and the rostrum carry 6 teeth, 3 on the carapace 

 and 3 on the rostrum; the foremost tooth is a little larger than the acute tip of the rostrum, 

 above which it is situated, so that the rostrum appears bidentate at the tip, not tridentate, 

 because there is no small tooth on the lower margin. The other specimen shows the same 

 toothing, but the rostral crest is less strongly arcuate and the foremost tooth of the rostrum 

 has the same size as the tip. 



In the i^' and 2°'' pair of legs the fingers are distinctly longer than the palm, but the 

 fingers of the 3''^ pair are a little shorter than it. 



The thelycum and the spiniform plate show a different form from that of Sic. lancifer 

 (vide: Report Challenger Macrura, 18SS, PI. 43, Fig. 4"), a species with which it is compared 

 by Nobili, probably due to the young age of these specimens.

 Ceylon (Miers); Singapore (Nobili); Thursday Island (Miers).

I male. 

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

 From 54 — 90 m. Fine grey sand; coarse sand with shells and stones, i female. 



Unfortunately the female from Stat. 51 is much injured, the carapace being broken 

 behind the rostrum ; therefore the male is described, which is probably adult, as the petasma 

 is fully developed. 



The male from Stat. 37 is 21,75 ""'"''• ^o"?' ^^e carapace, rostrum included, 7 mm., 

 without it 4,75 mm. 



Sic. irispinosa bears the closest resemblance to Sic. carinata Olivi = sculpta H. M.-Kdw.,
