DRAWIDA LONGATRIA Gates 1925 



Drawida longatria Gates, Ann. Mag. Nat. Hist., ser. 9, vol. 16, p. 50, 1925. 



Distribution. -- Mandalay , Thazi. 



Remarks. — In a collection from Mandalay are two forms which 

 appear superficially to be different from each other as well as from 

 D. longatria. The spermathecal atrium, the vas deferens, and the 

 prostates are, however, characteristic of D. longatria. 



In specimens of the first form definitely marked genital papillae 

 are lacking; the male porophores are bluntly rounded projections in 

 10/11; the testis sacs lie in both x and xi; the gizzards are two or 

 three in xv-xvii; the atria are short, 20-30 mm. long, with large 

 loosely coiled loops and with the free end very slightly enlarged. 



In specimens of the second form genital papillae are also lacking; 

 the male porophores are slightly elevated, fiat-surfaced, oval areas 

 extending across 10/11, about three-fourths of the papilla on segment 

 X, the portion of the papilla on x surrounded by a narrow strip of 

 whitish tissue; the male pore a crescentic groove, with the horns of the 

 crescent directed forward, the pore located on the posterior part of 

 the papilla; two or three gizzards in xv-xviii. 



DRAWIDA TUMID A, new species 



Description oj the type-specimen, external characteristics (Cat. No. 

 19253, U.S.N. M.).— Length, 100 mm. Diameter, 4 mm. Number 

 of segments 197. Color: Grayish, except on the clitellum where the 

 segments are deep red. 



The prostomium is prolobous. 



Segments vii-xx, inclusive, have two secondary furrows per segment, 

 one anterior to and the other posterior to the setae of the segment. 

 Slighter tertiary furrows are present on x and xi. 



Functional dorsal pores are lacking. 



The setae begin on segment two and are closely paired; ah is equal 

 to cd, aa is less than be, and dd is greater than one-half of the circum- 

 ference. 



The clitellum is on x-xiii (4). 



The male pores are in 10/11, in be, nearer b than c, on the tops of 

 roughly conical papillae. 



The female pores are in 11/12 in line with b. 



The spermathecal apertures are in 7/8 in line with c. 



The body wall in he near h is thrown into a longitudinal ridge on 

 each side, extending from 9/10 to the setae of xi. Two papillae are 

 seated on each ridge. The body wall between the two ridges is 

 grayish instead of red. The whitish male porophores are on th« 

 posterior end of the ridges and are roughly conical with the pointed 

 tip directed slightly inward and posteriorly. The anterior papillae
