longitudinal septa separating this from the lateral compart- 

 ment. It lies between the penultimate and antepenultimate pair 

 of legs. 



The oviducts cross before opening to the exterior. The 

 right oviduct passes under the rectum, and the left over the 

 rectum. They meet by opening into a common vestibule, 

 which in its turn opens to the exterior immediately ventral to 

 the anus. It has not been ascertained how far this arrange- 

 ment, which differs from that observed by Moseley, is a normal 

 one. The young undergo nearly the whole of their develop- 

 ment within the uterus. They possess at birth the full number 

 of appendages, and differ from the parent only in size and 

 colour.] 



NOTES ON ADDITIONAL GLANDULAR BODIES IN THE LEGS 



[CRURAL GLANDS]. 



1. They are present in all except the first. 



2. They open externally to the nephridia (PI. 51, fig. 20), 

 except in the fourth and fifth pairs of legs, in which they are 

 internal. 



3. A muscular layer covers the whole gland, consisting, I 

 believe, of an oblique circular layer. 



4. The accessory gland in the male (fig. 43, ag) is probably 

 a modification of one of these organs. 



[The structure and relations of these glands may be best 

 understood by reference to PI. 51, fig. 20. Each consists of a 

 dilated vesicular portion (fgl) placed in the lateral compart- 

 ment of the body cavity in the foot, and of a narrow duct 

 leading to the exterior, and opening on the ventral surface 

 amongst the papillae of the second row (counting from the in- 

 ternal of the three foot pads fig. 20 P). 



The vesicular portion is lined by columnar cells, with very 

 large oval nuclei, while the duct is lined by cells similar to 

 the epidermic cells, with which they are continuous at the 

 opening. 



In the last (i;th) leg of the males of this species, this gland 

 (vide above, note 4) possesses a slit-like opening placed at the
