a much more posterior position than usual ; on the one side the 

 sac was situated in segment xii, bulging back septum 12/13; on 

 the other it extended back into xiii. The forward connection 

 of the sac with its place of origin is by means of a neck, as in 

 D. ghatensis ; but I could not isolate the neck cleanly from the 

 surrounding structures, for example from the septa through 

 which it passes ; there was certainly a continuity of structure 

 between it and septum 11/12. One testis-sac was opened and 

 an attempt was made to turn out its contents and to identify the 

 testis and funnel, but it was not successful; the contents were 

 very firm, and not separable from the inner surface of the wall of 

 the sac. 



The vas deferens leads forwards from the testis-sac, and 

 forms a very fine and tightly coiled tube, which joins the prostate 

 rather lower down than its middle, i.e. rather nearer its ectal 

 than its ental end. The prostate is a softish white, not shiny, 

 closely curled cylindrical structure, of about the same diameter 

 throughout, of moderate size and without any differentiated 

 duct ; it is contained in segment x. 



The ovarian chamber does not reach the dorsal body-wall. 

 The ovisacs are small and finger-shaped ; they extend back into 

 segment xiii. 



The spermathecal ampulla is small and globular ; the duct, 

 thin and much coiled at first, and afterwards with a wavy course, 

 runs downwards on the posterior face of septum yj^. Where 

 it pierces the body-wall there arises a long stalked appendage, the 

 most conspicuous part of the whole apparatus ; it stands erect 

 in segment vii, free from and in front of the septum; its ental 

 portion is dilated in the form of an elongated cone with rounded 

 tip ; the stalk which connects this with the body- wall is fairly 

 stout, somewhat curved, smooth and slightly shiny, and longer 

 than the dilated ental portion. Fig. 3 represents the appearance 

 of this atrial appendage under the low power of the microscope ; 

 the lumen of the dilated portion was empty. 



Remarks. — The relationships of this form are with the former 

 group. The coihng of the prostate is as marked as in D. affinis, 

 and the atrial appendage of the spermathecal apparatus is more 

 marked and of a more characteristic shape. The resemblance of 

 the testis-sac to that of D. ghatensis (14) has been mentioned. It is 

 curious that the last heart is in segment viii (not ix, as usual), 

 and that viii should contain two pairs of hearts.
