Stat. 221. Nov. 4. 6°24'S., I24°39'E. Banda Sea. 2798 m. Bottom solid bluish grey mud 

 with foraminiferae, covered by a 5 cm. thick layer of brovvn mud, uppermost 

 layer of foraminiferae. 1 adult specimen. 



Unfortunately this specimen is much damaged, it has 110 abdomen and the three posterior 

 legs are also wanting, one of these legs and parts of tvvo other ones are lying loose in the 

 tube. Carapace 25 mm. long from the orbital to the posterior margin, rostrum, measured 

 in a straight line from the orbital margin to the apex, 13,4 mm. There are 7 teeth on the 

 upper margin of the rostrum proper and 9 on the dorsal crest of the carapace, of which the 

 first five are movable, being distinctly articulated which is not the case in the others; lower 

 margin with 6 teeth, the i st of which stands at the far end of basal antennular article. Antennular 

 peduncle a little shorter than the rostrum, the difference as long as 3 rd antennular article; 2 nd 

 article one and a half as long as 3 rd , stylocerite acuminate, as long as basal article. Antennal 

 scale 15 mm. long, a little more than half as long as the carapace; terminal spine of the 

 outer margin shorter than the obtuse tip of the lamella. 



The external maxillipeds reach by one fourth their terminal joint beyond the antennal 

 scale, while the i st pair of legs reach to the tip of the latter, being slightly shorter than the 

 external maxillipeds. 



The peraeopods of the 2 nd pair extend by the chela and the four last joints of the 

 carpus beyond the distal extremity of the antennal peduncle; the carpus is 10-articulate, the i st 

 and the last or io th annulation are longer than the rest and the i st is slightly longer than the 

 last; the rest are a little unequal, the j th — g th are of equal length and the shortest of all. 



General distribution: Xear Banda Island (Bate); Philippine Islands (Bate); Bay 

 of Bengal (Alcock). 



Heterocarpus A. M.-Edw. 



The genus Heterocarpus A. M.-Edw., chiefly characterized by the longitudinal carinae 

 of the carapace in addition to the multiarticulate carpus of the 2 nd pair of legs which are of 

 unequal length and size, is nowadays represented by about 20 species and 1 variety, that are 

 distributed throughout the Atlantic and the Indopacific regions. Heteroc. ensifer A. M.-Edw., 

 for which this genus was established in 1881, was captured by the expedition of the "Blake" 

 (1877 — 1880) off the islands of St. Kitts, Montserrat, Barbados and Grenada, West-Indies; 

 specimens of the same species, however, had already been taken in 1874 by the "Challenger" 

 between the Philippine Islands and Borneo. Heteroc. ensifer has also been recorded from the 

 Hawaiian Islands, New Britain and the Sagami Bay, Japan, so that its range is rather extensive. 

 Heteroc. carinatus (S. I. Smith), established on a young specimen from the east coast of the 

 United States, must no doubt be considered as identical with this species. A new variety 

 parvispina was obtained by the "Siboga" in the Bali Sea, north of Sulu Island and near the
