a long curved prong, which surpasses the external lamina in 
length, and a much shorter prong, the apex of which over- 
hangs the base of the long prong.

Hoplurorhachis Hoset, sp. n. (Fig. 13, p. 441.) 
Resembling the preceding in colour, but easily recognizable 
by being more coarsely granular, having the pore closer to 
the side margin (barely three diameters from it on the twelfth 
segment), the anterior and posterior edges of the keels more 
coarsely serrulate, the process at the base of the posterior side 
more dentiform and less triangular, being narrower at the 
base; the tail broader, with the processes shorter, and the 
infero-lateral tubercle on the anal segment much longer; and, 
lastly, by the form of the copulatory feet, the ramus of this 
organ being distinctly curved when viewed from the side and 
terminating in two processes—an outer long curved prong, 
the apex of which is bent at right angles, and an inner branch, 
which is subdivided into a laminate portion and a two-pronged 
branch. 
Length 69 millim., width 13. 
Loc. Baram (Borneo). One example obtained by C. Hose.

Phractodesmus, Cook, Brandtia, i. p. 1 (1896). 
Phractodesmus Fidley?, sp. n. 
2? .— Colour a uniform blackish brown, with a longitudinal 
white dorsal band (2—2°5 millim. broad) passing from behind 
the border of the first tergite to the posterior border of the 
nineteenth ; legs and antennee fuscous; sterna and bases of 
legs pale. 
Antenne longer than the width of the first segment, shorter 
than that of the second. 
First tergite broadest along the anterior border, which is 
straight and transverse; the anterior angles not produced 
forwards, but continuous with the anterior border. 
Dorsal surface of all the segments thickly granular, the 
rows of tubercles distinct even on the first tergite; keels 
depressed, their edges smooth, the anterior and lateral being 
slightly thickened, the latter lobulate, the former basally 
shouldered ; the anterior angles bluntly rounded, forming an 
obtuse angle in the posterior half of the body, an acute one in 
the anterior half; the posterior angle not rounded, square or 
pointed, but not spiniform ; porous area large, a diameter or
