but not quite as broad as inner, broader distally than basally, apex 

 rounded-truncate ; in J extending almost to telsonic apex, general 

 shape the same as in $ but smaller and narrower ; margins of both 

 rami in both sexes entire.

Colour: Head and peraeon brownish, segments 5-7 lighter than 

 the anterior segments, especially at the sides, margins of the 

 segments as well as those of epistome and peduncles of antennae 

 orange, pleon dark brown, telson and basal half of uropods dark 

 brown, the apex of telson to half-way along margins and the distal 

 half of uropods white, basal margins of uropods orange.

EXOSPHAEROMA VABICOLOR, H. Sp. 



(Plate XXXII. C.) 



Body rather strongly convex, smooth, the epimera scarcely visible 

 in dorsal view. Anterior margin of head with 1 fairly deep and 

 1 shallow indentation on either side of median point. Peraeon 

 segments quite smooth ; in some $ 3 there are 2 very obscure 

 submedian tubercles (mere indications), which however are totally 

 absent in other 3 3 and in ? ? . Epimera bent downwards almost 

 vertically, not so separated as in E. gig as, the antero-lateral angles 

 obsolete, the postero-lateral subacute. Pleon with 2 very obscure 

 submedian tubercles on hind margin of segment 4 in both sexes. 

 Telson as long as broad, sides almost straight, apex rounded, surface 

 smooth with 2 blunt, submedian carinae, with groove between them, 

 on basal portion, the carinae more prominent distally than basally. 



Antennae similar to those of the last species, flagellum of 1st 

 10-jointed, of 2nd 14-jointed. 



Epistome similar to that of the last species but sides concave. 



Mandibles, cutting-edge 4-dentate in left, 3-dentate in right, 

 secondary cutting-edge in left 3-den.tate, spine-row with ca. 6 spines 

 in left, ca. 9 in right, palp stout, 2nd joint longest, 2nd and 3rd 

 joints strongly fringed. 



First maxilla, outer plate with 10 spines. 



Second maxilla, outer and middle plates both with 10 spines. 



Maxilliped normal. 



First peraeopod, 2nd joint with 1 strong outstanding spine on 

 middle of outer margin, inner apical angles of 4th, 5th and 6th joints
