even on the fifth segment ; posterior angle acute, but havclly 

 spiniform even at the end of the body. Pores separated by 

 about their own diameter from the Literal 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. 



^ . — Smaller than female (length 55 millim., width of fifth 

 segment 9*8), with larger keels. Gopulatory 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 Ilodesmus. 



Genus Taphodesmus, Cook.

Taphodesmus sanguineus^ sp. n. (Figg. 14, 14 a.) 



$ . — Colour black, the marginal thickening of the keels 

 blood-red. 



Anteiince 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, sabequal 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
