440 Mr. R. I. Pocock on new 
even on the fifth segment; posterior angle acute, but hardly 
spiniform even at the end of the body. Pores separated by 
about their own diameter from the lateral border. 
Caudal process broad, its border widely convex. 
Sterna with very short tuberculiform processes at the bases 
of the legs. 
Measurements in millimetres.—Total length 73; width of 
second segment 10, of fifth 12. 
3g —Smaller than female (length 55 millim., width of fifth 
segment 9°8), with larger keels. Copulatory legs with hairy 
portion of distal segment short, much shorter than distal 
portion, which is long, simple, and stout, with a strong curva- 
ture, its distal portion being directed upwards and outwards, 
ending in a slender filiform tip. 
Loc. Albay, S.E. Luzon (J. Whitehead). 
Perhaps identical with dorsalis of Peters from Luzon, 
which, according to Peters, is nearly allied to margaritiferus, 
Gerv. (= Meyenii, Brandt). This new form differs from 
margaritiferus, according to specimens in the British Museum, 
in being much more coarsely granular, with the posterior 
angles of the keels less acute. In spite of the fact that in 
this species the copulatory feet do not cross and are not 
branched, I believe it belongs to L/lodesmus, 
Genus TAPHODESMUS, Cook. 
Taphodesmus, Cook, Brandtia, i. p. 1 (1896). 
Taphodesmus sanguineus, sp.n. (Figg. 14, 14 a.) 
?.—COolour black, the marginal thickening of the keels 
blood-red. 
Antenne a little exceeding width of first tergite in length, 
much less than width of second. 
Dorsum of segments strongly convex; keels small, the 
three rows of tubercles conspicuous, subequal in size, the 
spaces between them and the upperside of the keels coarsely 
granular, the marginal thickenings of the keels irregularly 
tubercular ; anterior angles of all the keels from the fourth 
backwards widely rounded, posterior angle squared or acute, 
not spiniform ; anterior edge of keels basally shouldered. 
Caudal process semicircularly rounded. 
Sterna not spined. 
¢.—Smaller than female and less convex. Copulatory 
feet closely applied along the inner edges of the distal segment, 
the terminal portion ending in three prongs, the proximal 
shorter, lightly curved, projecting outwards, the distal two
