Stat. 316. Febr. 19, 1900. 7° 19.4 S., ii6°49'.5E. Bali Sea. 538 m. Bottom fine, dark brown 

 sandy mud. i female without eggs. 



This female is not yet full-grown, it measures 73 mm. from the frontal margin of the 

 carapace to tip of telson, while the type specimen from the Hawaiian Islands, an ovigerous 

 female, was 99,7 mm. long. Of the specimen from the Bali Sea the carapace, measured in the 

 middle line, is 18 mm. long, the abdomen 55 mm., so that the latter is 3-times as long as 

 the carapace. The greatest height of the carapace, at the level of the branchial regions, is 

 7Y2 mm., so that the carapace appears a little more than twice as long as high; in a side 

 view it narrows rather much anteriorly, so that at the posterior end of the branchiostegal sinus 

 the carapace appears only half as high as at the level of the branchial regions. The frontal 

 margin, above the base of the eye-peduncles, appears broadly rounded when looked at from 

 above, but is little prominent. The carapace, the posterior margin of which is emarginate, is 

 rounded dorsally and armed anteriorly, just behind the front, with a compressed, obliquely- 

 ascendant tooth, of which the acute spiniform apex reaches almost to the level of the front and 

 the sharply carinate, upper edge of this tooth is slightly concave; the tooth is one millimeter 

 high. Outer orbital angle obtuse, projecting a little more forward than the front, post-antennular 

 angle defined, blunt and separated both from the outer orbital angle and from the rounded 

 anterolateral angle of the carapace by a shallow sinus. Branchiostegal spine well developed, the 

 linear distance between their apices being 5 mm. long. The anterolateral angle of the carapace 

 is followed by the branchiostegal sinus, which is somewhat longer than the two sinuses situated 

 before it. The sides of the carapace are apparently smooth, without ridges. 



Unfortunately on the photograph of the type the frontal tooth is quite invisible. 



Abdomen (Fig. 6r) not carinate. While the i^', 3''^ and 4'** terga are rounded, the 2"'^ and 

 the 3''' are even slightly flattened dorsally. The 6^^ segment which is 10 mm. long, measured 

 dorsally, and 6 mm. broad, is half as long again as the 5'"^ (6-/3 mm.); it is much compressed, but 

 the slightly convex upper margin is blunt, smooth, and posteriorly truncate. The telson, 8 mm. 

 long, is four-fifths as long as the 6"^ segment; the tip (Fig. 6d) shows a shallow emargination 

 in the middle, unfortunately the spinules at the tip are mostly lost, but 4 or 5 pairs occur no 

 doubt in this species. The tip is 0,8 mm. broad and the telson is about twice as broad, viz. 

 1,7 mm., at the base; the spinules at the outer angles of the tip are probably 0,5 mm. long, 

 the other spinules are a little shorter. The upper surface of the telson is flattened, but the 

 posterior third is grooved, the groove passing gradually into the flattened surface. The endopodite 

 of the caudal swimmeret projects about by one-third, the exopodite almost by half its length 

 beyond the tip of the telson. 



According to the original description, the eyes should be considerably enlarged distally. 

 In the female from Stat. 316, however, this is not the case. The eye-peduncles, indeed, that 

 reach about to the distal third of i'^' antennular article, are only twice as long as broad at the 

 base of the. corneae, where they are a little enlarged; the corneae are half as long as the 

 eyestalks and of a grayish colour, their posterior margin is blackish and there is a blackish 

 spot on the outer side. 



The antennular peduncle reaches a little beyond the middle of the scaphocerite, basal
