parallel to the long axis of the body. The second and third segments 

 produced inferiorly below the level of the first and of the rest, carinate 

 at the sides, but only very obsoletely carinate above. The fourth carinate 

 above and at the sides. The rest of the somites with their posterior 

 half carinate from summit to base; with five carinse on the dorsum 

 between the poriferous carina? and about twelve, decreasing in size, 

 between the base of the legs and the poriferous carina; the carina? 

 entire, marked but not divided by a fine transverse sulcus and not 

 extending posteriorly beyond the margin of the tergite. The pore situated 

 on a rounded , smooth tubercle, which is placed on the anterior portion 

 of one of the keels; areas between the keels not sculptured. The 

 cylindrical portion of the somites very closely granular in front, finely 

 ridged behind. Anal tergite not carinate , with convex posterior border ; 

 anal valves convex, with margins not compressed. 

 No. of somites about 74. 



Length up to about 42 mm. 



Thic species is rather larger than C. calva, from which it may be 

 recognised by its almost entirely undivided crests, and by the absence 

 of carina? from the dorsum of the second and third tergites. 



76. Cambala dentata, sp. n. 



Java: Buitenzorg. One specimen. 



Resembling C. calva in size and colour, except that the head is 

 fuscous above , and the pale of the lower surface not distinctly defined. 

 The head is closely hairy below ; on one side the eyes consist of three 

 distinct ocelli, on the other side there are two smaller ocelli situated 

 behind the three. The first tergite it distinctly carinate laterally; and 

 the second and third furnished with distinct carinae above. The keels 

 are more strongly developed , evidently bifid and extend at the hinder 

 end of the body in the form of teeth beyond the posterior border of 

 the tergites. Moreover the pore-bearing tubercle is larger than in calva. 



No. of segments 56. 



Length about 18 mm.

 half the long diameter of an eye.
