the fringed cup-like process well produced ; the sixth joint large, oval, the very oblique 

 sinuous palm forming three lobes, of which the centre one is broadest, the finger 

 closing at the tliird into a pocket which meets the hind margin at a well-defined 

 angle. 



First and second gnathopods. $ . These are similar to the first in the 6 , but smaller, 

 and the sixth joint of tlie second is rather longer and more slender than that of the 

 first. 



Pcrceopods. These are tolerably robust and spinosc. In the last three pairs the second 

 joint is l)roadly oval, considerably larger in the fifth than in the two preceding pairs. 

 There are simple accessoi-y branchiae on the first four pairs of the peraeopods. 



First and second nropods. These have lateral spines on both rami. 



Third iiropods. The ramus is as long as the peduncle. 



Tel son. Squared at the base, then broadly rounded, with two distant setules on the 

 broad apical margin. 



Colour. Dusky in spirit. 



Length. A fifth of an inch, 5 mm. 



Hub. Lagoa Santa, from watercourse. The specimens belong to the Copenhagen 

 Museum, and were obtained by Warming, after whom the species is named. The 

 species seems most nearly related to Hyulella Lnbondrskii (Wrzesniovvski), to judge by 

 the description of tliat species, which is unhappily unaccompanied by figures. 



Htalella Meinerti, n. sp (Plate 32 B.) 



The first three pairs of side-plates are deeper than broad ; the third plcon-segment has 

 the postero-lateral corners acutely qiiadrate. 



Eyes. Black, usually wider apart than their diameter. 



First antennce. Slender, more than half as long as the second pair; third joint of the 

 peduncle nearly as long as the second, but by its slenderness resembling the joints of 

 the flagellum ; flagelhim composed of nine or ten elongate joints. 



Second antennce. Slender, more than half as long as the body ; penultimate joint of 

 peduncle rather long, ultimate still longer, the flagellum consisting of thirteen to fifteen 

 elongate joints. 



First gnathopods. 6 . The fourth joint has a scabrous, rather prominently rounded 

 apex ; the fifth is strongly widened distally, with the projecting apex scabrous and 

 rounded ; the sixth joint is much shorter, scarcely widening to the transverse well- 

 defined palm, and, as is so commonly the case i]i the genus, inclined athwart the 

 preceding joint. 



Second gnathopods. 6 . The second joint is narrow, the fourth as in the preceding 



pair ; the fifth with the usual cup-like spine-fringed lobe ; the sixth mucli longer than 



broad, its basal part narrow, rather abruptly widening at the boss which defines the 



-oblique, slightly sinuous palm, the finger closing completely over the palm, with its 



apex on the surface within the boss. 



First and second gnathopods. 2 . These are small ; the fourth joint has a rounded
