beyond the middle of the visible part of first antennular article and is slightly turned upward; 

 it is continued into the obtuse rostral carina, which in a lateral view is not quite concealed 

 by the orbital hoods, from which it is separated by narrow grooves; the rostral carina gradually 

 broadens backward and passes at the base of the orbital hoods into the surface of the carapace. 

 According to Alcock and Anderson (1. c. 1 894) tire eyes should be markedly deficient in 

 pio-ment; in this specimen, however, the black pigment is quite plentiful, reaching almost to 

 the base of the orbital hoods and, at either side of the orbital region, specks of the same 

 pigment occur, just outside the eyes. 



In the male of this species the abdominal pleura are of moderate width and subacute, 

 accordino- to the figure in the "Illustrations", but in the female taken by the "Siboga" they 

 are rounded inferiorly and as well developed as in other species. 



Telson elono-ate, 4,5-times as long as the posterior margin is broad, width at the base 

 almost twice that of the posterior margin, the proportion being as 15:8; spinules of the upper 



surface o 28 0,3 mm. long, anterior pair situated just on the middle, at some distance from 



the lateral maro-ins, posterior pair almost one and a half as far distant from the posterior 

 marcrin as from the anterior pair, the proportion between these distances being 11 : 8 ; posterior 

 maro-in rounded, rather prominent, the inner longer spines are rather short, though just reaching 

 beyond the posterior margin, the outer are half as long; upper surface of the telson flattened, 



not grooved. 



Second antennular article four times as long as thick, one and a half as long as the 

 visible part of the first, 3''^ article two-thirds of the latter ; stylocerite ending in a slender spine, 

 that, just reaching beyond the i'^' article, is turned outward and upward. In the type 

 specimen figured by Coutiere (1. c.) the stylocerite is directed straightly forward. 



Basicerite with well-developed spine, 0,34 mm. long. Carpocerite slender, extending beyond 

 the antennular peduncle almost by the length of t,"^ article ; in the figure 3' of Coutiere's quoted 

 paper the carpocerite is not visible, I wish, however, to remark that in the figure 5 of the 

 "Illustrations" the carpocerite appears decidedly longer than the antennular peduncle. Like in the 

 typical specimen figured by Professor Coutiere, the blade of the scaphocerite, the outer margin 

 of which is nearly straight, reaches as far forward as the antennular peduncle, but differently 

 from his figure 3', the terminal spine, that extends as far forward as the carpocerite, projects 

 with half its length beyond the tip of the blade, in the quoted figure, however, it hardly 

 extends beyond it; the blade is fringed with long hairs. 



Terminal joint of external maxillipeds slender, 7-times as long as broad at its base, 

 narrowing towards the distal extremity and 3-times as long as the preceding joint. The left 

 leo- of the second pair (the right is missing) extends almost with four segments of the carpus 

 beyond the tip of the carpocerite. Merus very slender, 10 — 11 -times as long as broad in the 

 middle ; it bears near the proximal end of the posterior margin a small tooth, that seems to 

 fit into a small hole at the distal extremity of the preceding joint. Carpal segments 2,16 mm., 

 1,06 mm., 0,46 mm., 0,55 mm. and 0,7 mm. long, chela 1,35 mm. long (palm 0,55 mm., fingers 

 0,8 mm.); the second segment, half as long as the first and one and a half as long as the 

 fifth, is 5-times as long as thick, the carpus appearing rather slender.
