which exists in mine, but that the two cornua opened separately into 

 the "corps ovale" ( = secondary vagina). Mayer apparently (/. c. 

 pi. C. p. 38) found a similar arrangement in E. indicus. Hunter, 

 Owen, and Miall and Greenwood all indicate an arrangement like 

 that which obtained in mine '. 



Fig. 8. 



Opening of urethra (U) into the urino-genital canal, about natural size (some- 

 what diagrammatic). The walls of the urino-genital canal are cut close 

 round the urethral eminence. M.C. Malpighian canals ; below (anterior 

 to) the letters is seen the constriction separating the vagina from the 

 urino-genital canal ; on the top of the urethral eminence is seen the 

 small free point ; below it is the cul-de-sac of the urino-genital canal. 



N.B. In the natural position the lower parts of the figure are anterior, the 

 upper parts posterior. 



The secondary vagina, which lies behind the neck of the bladder, 

 is separated by a constriction, leaving only a very small opening, from 

 the urino-genital chamber, which is marked off by the livid blue 

 colour of its mucous membrane from the parts already described. On 

 each side of this median constriction lies a small obliquely-placed slit, 

 about | inch long, and admitting a probe for about the same dis- 

 tance into the small sacs (canals of Malpighi), of which they are the 

 openings. Exactly the same arrangement occurs in the Indian 



1 In a specimen (277^ a) in the College of Surgeons of the uterus &c. of E. 

 imdicus, the " corpus uteri " is very much more capacious than in my (young) 

 specimen, is about 7 inches long, and is only separated off from the " secondary 

 vagina " by a prominent zonary fold of mucous membrane. The calibres of these 

 two chambers are about the same.
