Stat. 89. Pulu Kaniungan Ketjil. 11 m. Bottom coral. 1 male. 



To the characters, mentioned by Miss Rathbun (1. c), the foUow- 

 ing may be added. Rostrum terminating anteriorly in two slender, 

 subacute teeth, separated by a broad interspace and with a smaller 

 spine on either side at base ; distance (0,5 mm.) between the 

 line, long 0,72 mm., uniting the tips of the two basal teeth, and 

 the line, long 0,4 mm., uniting the tips of the two apical teeth, 

 only one-fourth longer than the length of the latter line. Ante- 

 penultimate thoracic sternum with a strongly compressed, acute 

 tooth, the two posterior sterna sharply carinated, the carinae with 

 subacute anterior extremity. 



Telson little shorter than earapace, deeply grooved, with 2 pairs 

 of microscopical spinules on the lateral borders of the groove. 

 Abdominal sterna toothed in the middle line. Pleura of the Ist, 

 3rd and 4th somite truncate with rounded posterior margin, pleuron 

 of 2nd very obtusely angulate or almost rounded inferiorly, 5th 

 pleuron also rounded. 



Antennular peduncle reaching about to the middle of the antennal 

 scale, scale hardly longer than broad. 



Carapace long 8 mm., abdomen 20 mm., entire length 28 mm. 



Sabinea O wen. 



Sabinea mdica n. sp. 



Stat. 65a. Very near Station 65. (7° O' S., 120° 34'. 5 E). Xorth 

 of ïanah Djampeah Island. From 400 m. Pale, grey mud, changing 

 during haul into coral bottom. One female without eggs. 



This species is very interesting, because no representatives of 

 the genus Sabinea were until at present known to occur in the 

 Indopacific, it differs moreover considerably from the three other 

 species of the genus.
