ON THE DEVELOPMENT OE PERIPATUS CAPENSIS. 
Fig. 4. Embryo in the same stage as the preceding, to show the manner in which it 
lies coiled up in its envelope within the uterus. The tip of the posterior 
extremity rests in the space between the antennae and against the front of 
the cephalic lobes. 
Fig. 5. A very slightly more advanced stage, much magnified. 
m. The buds which form the processes corresponding to the mandibles 
of Myriopods. 
Fig. 6. Slightly further advanced stage, seen from the side, m as before. 
Fig. 7. More advanced. The first pair of body-members (1) is turning inwards towards 
the mouth, and is overlapped by the down-growing processes (m). The 
labrum (7) begins to cover over the mouth. 
Fig. 8. Further stage. The processes ( m ) have come further down over the members (1). 
These members have turned further inwards towards the mouth ; and on each 
there is seen one claw of the pair of claws which they bear in common with 
the ambulatory members, and which are modified into the horny jaws = 
maxillae. 
e. Commencement of the eye ; d. End of duct of slime-gland. 
Fig. 9. Further stage. Both masticating claws are visible on each side. The process 
(m) is much folded on its inner margin, and its folds extend up on to the 
cephalic lobes.. It has fused with the superficial structures about the base 
of the first and second pair of members (1 and 2), and thus the formation of 
the tumid plications surrounding the external oral aperture in the adult is 
nearly completed. 
Fig. 10. The plications extending from the base of the processes (m) are continuous 
across the cephalic lobes, and the labrum is thus shut in with the maxillae 
within the external oral aperture. The antennae exhibit a very advanced 
state of jointing. 
Fig. 11. Maxillary claws from the specimen figured in fig. 10. 
a. Anterior ; b. Posterior claw. 
Fig. 12. Ambulatory member from the same, showing the way in which the claws 
appear in induplications of the extremities of the members.
