Material examined : Six specimens, one ovigerous, in coral, 

 Teviatoa Reef, Raiatea Island, Society Islands, August 21, 1931. 

 One ovigerous female, and one male, Venus Point Reef, Tahiti, 

 August 15, 1931. One large specimen, in coral, Temukus Roads, 

 Bali, Dutch East Indies, October 25, 1931. All collected by the 

 "Alva." 



Technical description : Rostrum short, acuminate, dorsally 

 carinate, from the apex, which is scarcely protruberant beyond 

 the frontal margin, to a point slightly posterior to the orbit ; orbits 

 large, convex, without an apical spine, composed of large, black 

 hemispherical facets. Carapace rather widely rounded dorsally, 

 laterally compressed, with the anterolateral margin closely ap- 

 pressed, rounded. Carapace length, including rostrum, 5 mm.; 

 rostrum, 0.5 mm. long; height of carapace in median area, 3 mm. 



The antennular peduncle has the visible portion of the first ar- 

 ticle about one-half of the length of the second article ; the second 

 article is about twice as long as the third article ; the flagellum is 

 two-branched, the upper, shorter branch is three-fifths as long as 

 the lower, and thicker, with a distal brush of setae; the outer 

 branch is one-half as long as the antennal flagellum. The stylo- 

 cerite is quite small with a fine denticle-like tip that does not ex- 

 tend beyond the margin of the related segment. 



The antennal scaphocerite is very short, with the distal outer 

 portion slightly but definitely outcurved, very acuminate; this 

 acuminate outer portion narrowed, equal to two-fifths of the entire 

 length of scaphocerite, its apex almost reaching the distal margin of 

 the third peduncular article of the antennulae ; the inner portion of 

 scaphocerite is only three-fifths as long as the outer and separated 

 from the latter distally by a small incision ; the inner portion is 

 distally very narrow, rounded, widening slightly proximally. The 

 second and third peduncular articles are slender, cylindrical, and 

 are as long as the antennular peduncle. The antennal flagellum is 

 fine and quite long, about twice the length of the longer antennular 

 whip. 



The abdominal terga are rather broadly rounded in the fe- 

 males, less so in the males ; the female brood pouch is very capaci- 

 ous. The telson is longish, one and two-thirds times as long as the 

 preceding segment, distally triangulate, with the apex bluntly 

 rounded, narrowed, setose; the dorsal surface is smooth, with a 

 median longitudinal wide sulcus and with three pairs of articu-
