Fig. 26. Male, transverse section of nerve cord near its anterior 
end. 848:1. | 
Figs. 27, 28. Female, transverse sections of the ventral hypo- 
dermis at the point of attachment of the neural lamella, in the most 
anterior trunk region; in Fig. 28 the ground substance of the hypo- 
dermis not shown. 848: 1. 
Figs. 29, 30. Chromophobic nerve cells of the cephalic ganglion. 
848 : 1. 
Fig. 31. Male, slightly oblique vertical longitudinal section of the 
nerve cord and neural lamella, from the most anterior trunk region; 
the upper part of the section lies to one side of the mid line. 848:1. 
Fig. 32. Female, horizontal longitudinal section of the nerve cord 
at the middle plane of its height. 528: 1. 
Fig. 35. Female, horizontal longitudinal section of the neural 
lamella, close to its insertion upon the hypodermis; the straight lines 
represent the boundaries of the contiguous musculature. 848 : 1. 
Fig. 34. Male, portion of a longitudinal section of the anterior : 
wall of the head, showing hypodermal elements; the cuticula not drawn. 
848 : 1. 
Fig. 35. Male, portion of a longitudinal section of the latero- 
anterior wall of the head, showing the ending of a cephalic nerve in 
the hypodermis; the cuticula lies contiguous to the left hand surface. 
848 : 1. 
Fig. 36. Female, cross section of cloacal ganglion, cloacal wall 
and ventral hypodermis. 528 : 1. 
Fig. 37. Female, cross section of the body wall of the left side 
of the middle trunk region. 848 : 1. 
Fig. 38. Longitudinal section of a muscle cell, showing the 
nucleus in its entire length. 848: 1. 
Fig. 39. Female, apparently bipolar chromophobic nerve cell from 
the dorsal hypodermis of the trunk; hypodermis shown only in outline. 
848 : 1. 
Fig. 40. Female, tangential section of the fibrous layer of the 
cuticula of the middle trunk region, showing its two deepest fibre 
layers and outlines of hypodermal nuclei beneath them; the axis of the 
arrow marks the long axis of the body. 848:1. | 
Fig. 41. Female, cross section of the cuticula and hypodermis of 
the outer wall of a lateral tail lobe, near its posterior end. 848: 1. 
Fig. 42. Female, cross section of the dorsal body wall, with a 
portion of the mesentery and uterus of the left side. 848: 1. 
Fig. 48. Male, cross section of ventro-median side of a tail lobe 
near its posterior end, the dorsal surface to the right; details of the 
fibrous layer of the cuticula not shown. 848: 1.
