about at the center of the dorsal face. Granulations (external glandu- 

 lar layer) are lacking on this duct portion, which is about one-half 

 as long as the gland, the prostate and duct together being 9-11 mm 

 long. The granulations can be scraped off from the prostatf^ revealing 

 a firm, rather slenderly tubular, glistening, central body, which de- 

 creases very gradually and only very slightly in width passing ectally. 

 The penial chamber projects conspicuously into the coelomic cavity 

 to a height of 11/2-2 mm, the dorsal surface smooth and regularly 

 convex. The diameter is less than the height. The penis is 1-11/2 mm 

 long, slightly widened at the base (dorsally). 



Laterally and dorsally septa 10/11 and 11/12 are attached to the 

 parietes close together. In spite of the fact that both specimens 

 were opened with considerable care, segment xi was opened by the 

 dorsal incision in each worm. An ovarian chamber of the horse- 

 shoe type is apparently lacking in this species. The ovarian segment 

 is filled with loose ova (2 specimens). The ovisacs are not fully 

 distended by ova and extend only into xiii and xiv or into xiv 

 and XV. 



The spermathecal ampulla is collapsed and contains only a small 

 quantity of whitish material. The duct is twisted into a number of 

 loops immediately under the ampulla and thence ectally is gradually 

 widened. The duct passes, without definite external demarcation, 

 into a rather digitiform atrium, which is in viii. In the wall of each 

 spermathecal atrium (4 spermathecae) is a single, "urn-shaped" 

 gland. The gland is almost spheroidal, pinkish, hard, rather large, 

 the diameter of the gland greater than the thickness of the atrium. 



Dorsal to each of the two genital markings of the first specimen 

 is a parietal gland that projects into the coelomic cavity. No gland 

 was found in the parietes of viii of the second specimen. 



Remarks. — Drawida gisti is close to D. hehoeiisis Stephenson, 

 1924 (from Burma), from which it is distinguished as follows: Re- 

 striction of gizzards to segments xii-xiv; binding of a stalk portion 

 of the prostate to the lateral face of the penial chamber by connec- 

 tive tissue ; greater length of the penis ; larger size of the spermathe- 

 cal atria; incomplete closure of the ovarian segment; presence of an 

 "urn-shaped" gland in the wall of each spermathecal atrium; pres- 

 ence of definite genital markings and their associated glands.
