18 NOTES ON MILLIPEDES. 



Legs. The legs start from the sides of the lower surface 

 of the body, there is only one pair to each segment, the last 

 pair of legs is generally longer than the rest. The number of 

 pairs of legs is invariably odd. 



Native Names for Centipedes. 



Malay, "Halipan" or " Lipan." 



Siamese, "Takhap." 



Centipedes are divided into two sub-classes : — 

 1st. Anaetiostigma. 



1. eyes, large, compound, faceted. 



2. antenna', widely separated at base, very long, thread like. 



3. body, composed of 15 segments, but only 8 dorsal plates, 



all of which, except the last, are furnished in the 

 middle of the hinder border with a single large 

 respiratory stigma. 



4. legs, very long, their tansi composed of a large number 



of minute segments. 



5. basal- segments of poison- jaws not united, 



Length of head and body (exclusive of antennae and legs)* 

 reaches over 2 inches (or 55 mm.) contains only one genus 

 Scutigera. 



2nd. AETIOSTIGMA. 



1. eyes, simple ocelli, or entirely absent. 



2. antenna', shorter, stouter and not thread-like. 



3. body, composed of from 15 to over 121 segments, each 



having its own dorsal plate ; the stigmata are 

 arranged in pairs and open on the sides of the body. 



4. legs, of moderate length, usually tipped with a claw.j 



5. basal-segments of poison-jaws united to form a coxal 



plate. Length of head and body (exclusive of antenna; 

 and legs) reaches over 11 inches (or 281 mm.) divided 

 into three orders, with many families and genera. 



* These dimensions only refer to the largest specimens I have myself 

 measured ; they may grow larger. 



t In the family Cermatobiidce (Order Lithohiomorpha), known from a 

 single species from Halmahira, the tarsi of the legs are many jointed.
