 wards and gradually dying' out in the prozonite. The sulci 

 are more strongly marked on the anterior than on the Tnedian 

 or posterior segments ; they are also more numei'ous tliere than 

 here, and conseqiiently reach nearer to the pore. The poi'es 

 start from the sixth segment and open in the metazonite; they 

 are located high on the sides and are scai'cely nearer to tlie 

 sutui'e than to the posterior margin of the segment. 



Last segment longish, with its posterior margin slightly 

 produced, the angle l)eing very wide, the apex rounded and 

 the margin of the segment scarcely emarginate laterally : it 

 just conceals the upper angles of the valves without overreach- 

 ing them. The valves are not prominent; they are globular 

 even along their margins, where some tiny, fleecy, pale hairs 

 ai'e to he seen. Anal sternite somewhat swollen, with almost 

 straight posterior margin. Sternites of the remaining seg- 

 ments of the body smooth, not striate. Stigmata very small. 



Legs moderately long ; se(U)iid joint with two I'ovvs each of 

 three bristles on its ventral surface, and a crown of six 

 bi'istles around its distal end (tliree anterior and three 

 posterioi"). 



Male : — The lowei' edge of tlie mandibular stem is strongly 



)roduced, rounded. Legs of the 

 first pair (fig. 32) showing a free 

 narrow plate at the base of the 

 posterior surface, which has been 

 considered as a ventral plate by 

 Dr. Attems ; a pair of basal joints 

 (L), largely expanded laterally, 

 Q^^ said to be coxfe,'^^ to which the 

 ti-acheal stalks f/.s-.J are attached ; 

 finally a telopodit composed of 

 five condensed -joints f^-6'j, of 

 which the two proximal (joints 

 two and three of the legs) are 



broader than the thi'ce distal joints ; the last joint is globulai', 



destitute of claw.

■'" The homology of ventral plate and coxuc is perhaps not quite 

 correct, and will have to be submitted to further examination.
