medium size. All the embryos in the uteri are of the same 

 age. 



Genus 7. Paraperipatus : — The legs have three pads. 

 The renal papillae of the fourth and fifth pairs (sometimes the 

 sixth as well) are situated in the proximal pad, completely 

 dividing it into two. The feet carry three papillae, one on the 

 anterior side, one on the posterior side, and one variable in 

 position. The outer blade of the jaws is simple, without a 

 small accessory tooth at the base. The inner blade has no 

 diastema, but has a row of small denticles. The male 

 genital pore is at the tip of a conical papilla. The ductus 

 ejaculatorius is short and median. The male accessory 

 glands C pygidial glands") debouch into a bulbus, which 

 opens to the exterior by a median pore above the anus. 

 There are no receptacula ovoruin. There are two recep- 

 tacula semiuis. The ova are small, devoid of volk, and arise 

 exogenously. The young at birth ai-e of medium size. 

 During the early uterine development they are provided with 

 a trophic sac, which becomes completely enclosed in the later 

 stages. 



III. Some Notes on the Type Specimen op 



E. SUMATRANUS. 



In order to compare the two species here described with 

 E. sumatranus (Horst), at the end of the summer 1 visited 

 the Leyden Museum. There I met with every courtesy on 

 the part of Dr. Horst, who first described the species in 

 question (8), and under whose care the type specimen is at 

 present. He kindly gave me every facility in its examination. 



The following notes made at the Leyden Museum confirm, 

 add to, and to some extent correct Dr. Horst's description. 



The colour of the dorsal surface of E. sumatranus is 

 dark brown, while that of the ventral surface is considerably 

 lighter. T^he white spots found on the dorsal surface are due 

 almost entirely to the broken condition of the large primary 

 papillte. The ventral surface completely lacks the pink
